Ocean and lake swimming are booming, and for good reason: the feeling of open water is nothing like a pool. The gear set is small (wetsuit, goggles, tow float, swim cap), but choosing wrong on any of them makes your first swims miserable. Here's exactly what to buy, what to skip, and how to stay safe.
By Colin B. · Published June 8, 2026 · Last reviewed June 8, 2026
The wetsuit is the big spend ($150-250). Goggles, tow float, and cap add another $70. Budget-brand wetsuit plus starter accessories lands around $220; our recommended picks come to about $350.

You need to already be a competent swimmer before open water. This guide assumes you can complete 500m in a pool without stopping. If you can't, get comfortable in a pool first; open water amplifies any anxiety you have about swimming.
Wetsuit fit matters more than wetsuit brand. A well-fitted $150 wetsuit beats a poorly-fitted $400 one. Wetsuits run small; if you're between sizes, go up. The test: you should be able to take a full deep breath without the chest panel compressing your lungs.
Never swim open water alone, especially to start. Find a group, a partner, or a supervised location. This isn't overcautious advice; it's the one rule all experienced OWS swimmers agree on without exception.
Your wetsuit is the single most important gear decision in open water swimming. It keeps you warm in cold water (most venues are 55-70°F), adds buoyancy that lifts your hips into proper swim position, and provides some sun and jellyfish protection. A swimming wetsuit is cut thinner and stretchier than a surfing wetsuit; don't substitute one for the other.
Wetsuits — what's the difference?
A few common shapes, each making a different trade.

Below 72°F
Buoyancy
Maximum
Best for Most beginners, cold lakes, early-morning ocean swims
Tradeoff Hot in warm water; can overheat above 75°F
Sleeveless
Full shoulder freedom, less warmth. Good for 68-76°F water.
Coverage
No arms
Best temp
68-76°F

Orca
Athlex Flex Full Wetsuit
$$$
★★★★★Our rating
Orca is one of the two most trusted names in triathlon and open-water gear, and the Athlex Flex is their beginner-accessible full wetsuit. Neoprene that stretches where you need it (shoulders especially), a smooth lining for easy removal, and a price that won't hurt if you discover OWS isn't your thing.
What we like
Orca's beginner line, built by a brand pros trust
Buoyancy lifts hips into proper swim position immediately
Stretchy shoulder panels won't fatigue your stroke
What to know
Sizing runs small; measure carefully before ordering
Full sleeve in warm water above 72°F will overheat you
Synergy makes decent starter wetsuits at prices that take the sting out of trying a new hobby. The Endorphin has buoyancy panels, acceptable stretch for beginner swim speeds, and solid zipper hardware. Not as plush as Orca, but it does the job for the first season.
What we like
Under $150, the lowest-risk way to try the sport
Full-sleeve cut provides cold water warmth and buoyancy
What to know
Stiffer neoprene than premium wetsuits; takes time to break in
The Fusion is the wetsuit you'll see on the starting line at most amateur triathlons. Exceptional hip-lift buoyancy, soft neoprene that doesn't restrict your stroke, and a panel layout refined over a decade of OWS-specific development. Once you know the sport is for you, this is the right step up.
What we like
Panel layout specifically developed for OWS swim position
Noticeably softer neoprene than budget wetsuits
What to know
Sizing varies from Orca; measure against Blueseventy's own chart
Premium price best justified once you're swimming twice a week
Open water goggles differ from pool goggles in two ways: the lens is UV-tinted (sun glare off the water's surface will blind you otherwise), and the field of view is wider so you can sight landmarks to navigate. Don't swim open water in standard pool goggles; you'll spend half your energy stopping to look up, and squinting the whole time.
Best starter
Aqua Sphere
Kayenne Goggles
$$
★★★★★Our rating
The Kayenne is the default open-water goggle recommendation for beginners for one reason: the 180-degree lens gives you peripheral vision you didn't know you needed. Sighting landmarks is natural, the UV-tinted lens cuts glare, and the seal fits most face shapes without leaking on the first try.
What we like
180-degree panoramic lens makes sighting navigation natural
UV-tinted lens cuts through glare on sunny open water swims
Forgiving seal fits most face shapes without leaking
What to know
Larger lens profile isn't ideal for very narrow faces
Anti-fog coating degrades with soap; rinse with water only
Under $20 and does what you need: tinted lens, reliable seal, comfortable strap. Not panoramic, but if you're not sure the sport will stick, this is a sensible first pair with real UV protection.
What we like
Under $20 with real UV tint for open water use
Speedo reliability at the lowest possible entry price
What to know
Narrower view; more head-lifting needed to sight landmarks
Seal is less comfortable on long swims than panoramic models
ROKA makes the goggles of choice for serious open-water swimmers. The R1's curved lens design extends peripheral vision beyond flat lenses, the strap never snaps on a hard race-day pull, and the optical clarity is noticeably better once you've trained your eye for it.
A tow float is a bright orange or pink inflatable buoy you clip to an ankle strap and drag behind you. It makes you visible to boats and jet skis from a long distance, gives you something to cling to if you cramp or need a rest, and most organized venues now require one. Budget $25-35 for a basic float. If you want to carry keys or a phone, storage buoys with a dry compartment run $40-60.
Best starter
New Wave
Swim Bubble Tow Float
$29.95 as of Jun 22, 2026
★★★★★Our rating· In Stock
Simple, bright, and purpose-built for open water safety. The New Wave Swim Bubble does the one thing it needs to: make you visible in open water. Easy to inflate, light ankle-strap drag, and a no-hesitation price. Most open water events require a tow float; this is the right one to start with.
What we like
High-vis orange makes you visible to boat traffic from far away
Light drag; easy to forget it's there after the first 10 minutes
What to know
No dry storage for keys or phone
Vinyl can develop slow leaks if stored deflated and folded tightly
The tow float you'll want once you're swimming solo or at venues where you need to carry your car key. The roll-top dry bag holds a key, an energy gel, and a small phone, and the 28L buoy is buoyant and visible enough to give you a real rest point if needed.
What we like
Drybag compartment holds a key, gel, and small phone safely
More rigid and visible than basic inflatable models
What to know
Noticeable drag when loaded; affects feel on speed intervals
Drybag zipper requires care to seal properly every time
In a pool, a cap is optional. In open water, it isn't. A neoprene cap retains meaningful body heat (your head accounts for a surprising percentage of heat loss), and a bright cap color makes you visible from shore and to watercraft. If your water is consistently above 75°F, a silicone cap works fine. Below 70°F, go neoprene.
Best starter
ZONE3
Neoprene Swim Cap
$52.15 as of Jun 22, 2026
★★★★★Our rating
Neoprene retains heat that silicone can't, and in most OWS venues (55-72°F is common), that matters. ZONE3 is a respected triathlon brand, and their neoprene cap is well-made, durable, and the cap most organized cold-water swims hand out at registration.
What we like
Retains significant body heat in cold water below 72°F
High-vis colors keep you visible from shore and boats
What to know
Too warm for water above 76°F; you will overheat
Takes a few swims to break in; initially tighter than silicone
For summer lake swimming or any water consistently above 75°F, a silicone cap is all you need. Silicone stretches to fit almost any head, won't snag hair, and costs under $10. Keep one in the bag for hot-water swims when the neoprene cap would overheat you.
What we like
Under $10, the cheapest piece of kit that still matters
Stretches to fit most head sizes without cutting circulation
Two items almost no beginner guide mentions and every regular open water swimmer uses. Body Glide prevents the painful wetsuit-collar rash that turns a great swim sour at the neck and underarms. Swimmer's earplugs prevent ear infections from repeated cold-water exposure, which is the most common chronic complaint among regular OWS swimmers.
Best starter
Body Glide
Original Anti-Chafe Balm
$
★★★★★Our rating
Apply where your wetsuit rubs: neck, underarms, wrists. Without it, after 30 minutes your wetsuit collar will have removed a layer of skin. Body Glide is waxy and won't degrade neoprene (Vaseline destroys wetsuit neoprene over time). The cheapest fix for the most common beginner problem.
What we like
Prevents the neck and underarm rash that ruins week-two swims
Safe for neoprene; petroleum-based alternatives destroy it
What to know
A stick goes fast if you're generous; buy two
Waxy texture won't spread in cold; warm it in your hand first
Cold water ear infections are the most common chronic complaint in OWS. Speedo's Biofuse plugs use a soft flanged design that seals without pressure, stays put during a swim, and is comfortable enough to forget about. Worth adding to your kit after the first month of regular swimming.
What we like
Flanged design seals without painful ear canal pressure
Stays put in chop; won't fall out mid-swim like foam plugs
What to know
Takes practice to insert correctly; plan a few test swims
Open water looks peaceful from the shore. It's more demanding than you expect, but also more rewarding. Here's what the first month looks like: building cold-water tolerance, learning to navigate without lane lines, and the moment it finally starts to feel natural.
You can already swim. That’s the prerequisite for open water swimming, and it’s not a small one. But “I can swim” and “I can swim in a lake” are different things, and your first month is mostly about learning what’s different rather than learning to swim.
The differences are real: no lane lines, no black stripe on the bottom, cold water that costs you energy before you’ve gone anywhere, sun glare that makes you feel half-blind, and navigation that requires a whole new skill. None of this is insurmountable. Most of it resolves within a few sessions. But going in knowing what to expect makes the first month dramatically less disorienting.
Week 1: The cold shock is the lesson
Your first open water swim will probably feel like an overreaction. You step in, the cold hits your face and neck, and your body does something involuntary: breathing speeds up, your heart rate spikes, your chest gets tight. This is cold shock, and it’s a physiological response, not a sign you’re in trouble.
The fix is slow entry. Walk in. Splash water on your face and neck before you submerge. Pause for thirty seconds after your ears go under. Your breathing will normalize within 60-90 seconds. Every time you swim, this gets faster and less dramatic. By week four, you’ll barely notice it.
Don’t start by trying to swim a distance. Your first session goal is getting comfortable with the entry and the environment. Swim 100m. Feel how different the water feels without a pool wall to hang onto. Come back in. That’s a successful first session.
One more thing about week one: don’t swim alone. This isn’t overcaution. It’s the rule that every experienced open water swimmer repeats without exception. Bring a buddy, swim in a group, or choose a venue with lifeguard supervision. Your tow float helps; a swim partner is better.
Week 2: Learning to sight
By week two, the cold entry is less shocking and you can focus on the actual skill that separates open water swimming from pool swimming: sighting.
Sighting is the technique of briefly lifting your eyes above the waterline to spot a landmark and confirm you’re swimming in the right direction. Without it, most swimmers drift 20-30% off course within the first 100m. The drift isn’t random; it tends to be consistent for each swimmer (most people pull slightly left or right), which means you’ll pattern your errors once you know to look for them.
The technique: every 8-10 strokes, as you’re beginning your arm pull and before your face rises to breathe, lift your eyes just above the waterline. Spot your landmark (a buoy, a tree, a tower on the far shore), then breathe and continue. You’re barely lifting your head; just your eyes. The whole sight takes half a second.
Getting this wrong is normal. Beginners either lift their heads too high (exhausting, slows you down, and the resulting hip drop kills your position) or don’t lift high enough to actually see anything. It takes 3-4 sessions to find the right height automatically. Once it’s automatic, you stop thinking about it.
Practice on a short loop: pick two landmarks, swim from one to the other sighting every 10 strokes, note how far you drifted. Correct and repeat. This drill teaches you more about navigation in one session than any amount of video-watching.
Week 3: Your stroke adapts
In a pool, you can breathe to the same side every time because you know the wall is 25m away. In open water, you want to breathe bilaterally (alternating sides) so you can see both sides of your course and aren’t locked into breathing toward glare or chop.
If you’re a one-sided pool swimmer, week three is when this catches up with you. Your neck will be sore the first few times you breathe to your off side. Your stroke timing will feel off. This is temporary, and working through it is worth it.
Your stroke will also naturally shorten in open water. The absence of a wall to push off changes your rhythm, and the chop (even mild wave action) interrupts your usual pattern. Don’t fight it. Most experienced OWS swimmers develop a slightly shorter, quicker stroke than their pool stroke, which is more stable in moving water.
The other thing that happens in week three: you stop swimming to the wrong place. The sighting finally works, your drift shrinks, and you feel the satisfaction of reaching a marker on the line you planned. That’s a disproportionately good feeling.
Open water swimming has a community, and that community is one of the nicest things about it. The people who swim in cold lakes at 7am are a self-selected group with a tolerance for mild misery and a genuine enthusiasm for sharing it with strangers. Group swims are how most people find their regular venues, their pacing partners, and (often) their best training advice.
Look for local Masters Swimming clubs (USMS in the US), outdoor swimming groups on Meetup or Facebook, or organized venue swims at reservoirs and lakes. Most are welcoming to beginners. Showing up to three group swims is usually enough to find at least one person at your pace who becomes a regular swim partner.
By the end of month one, you have four things: a working entry routine, functional sighting, a bilateral-ish breathing pattern, and at least the start of a regular swim spot. That’s the foundation. Everything from here is just volume and distance.
What will still feel hard
A few things don’t resolve in month one and shouldn’t be expected to:
Cold acclimatization takes longer. Your tolerance for cold water builds over the course of a full season, not four weeks. The first swim of a new season always feels colder than the last swim of the previous one. This is normal; it comes back fast.
Turns and navigation at pace. Sighting while swimming slowly is one skill. Sighting while trying to hold your pace is harder. This is a month-three problem.
Open water anxiety. Some swimmers feel a baseline unease about deep water, murky water, and the absence of a bottom to see. For most people this fades with exposure. If it doesn’t fade after a full season, that’s worth paying attention to.
What to do next
The obvious next step is distance. If you swam 400m swims in week one, aim for 800m by the end of month two. But don’t only increase distance; vary your venues. Different water temperatures, different chop, different navigation challenges. Each new environment teaches you something a familiar one doesn’t.
And if month one has convinced you this is the sport, consider a local open water event. Most areas have beginner-friendly 1km swims in the calendar. Racing (even loosely) in a group resets your sense of pace and introduces you to a community you couldn’t have found otherwise.
Save your money
What you don't need yet
Beginners get pressured to buy a lot of stuff that doesn't help them play
better. Here's what we'd skip on day one.
A GPS swim watch — Great for tracking intervals eventually, but learning to sight landmarks comes first. A $400 watch doesn't help you build the habit.
Wetsuit gloves and socks — Unless your water is below 55°F, these are race-day accessories. You won't miss them in your first season.
A center-mount snorkel — Useful for focused pool stroke work. Useless in open water where bilateral breathing is the actual skill to develop.
Open water fins — Training tools for experienced swimmers refining kick mechanics. Learn to navigate and sight first.
A wetsuit changing mat — A beach towel on the ground works fine for the first season. Don't buy gear that solves a problem you haven't felt yet.

Most guides put 60°F (15°C) as the practical minimum for beginners without cold-water training. With a full wetsuit and neoprene cap, 55°F is manageable for short swims. Below 50°F is a specialized cold-water pursuit requiring dedicated acclimatization, not a beginner activity.
Do I need a wetsuit, or can I swim without one?
In water above 75°F you don't strictly need one, though the buoyancy still helps. Below 72°F, a wetsuit transitions from nice-to-have to essential safety gear. The cold shock response at 65°F or below can cause involuntary gasping and hyperventilation within seconds of immersion; a wetsuit significantly reduces this risk.
Is open water swimming dangerous?
Meaningfully more so than pool swimming, and much less so than most people fear if you take it seriously. The risks are cold shock, exhaustion, and disorientation. All three are managed by swimming with others, using a tow float, knowing your water temperature, and building distances gradually. Most accidents involve solo swimmers who overestimated their fitness in cold water.
What's the difference between a triathlon wetsuit and a surfing wetsuit?
Triathlon and open water wetsuits are cut for prone (horizontal) body position, use thin 1.5-3mm neoprene for flexibility, and are designed to be stripped off quickly. Surfing wetsuits are thicker (4-6mm), stiffer, and cut for standing and paddling. Surfing in a tri wetsuit is fine briefly; swimming laps in a surf wetsuit is exhausting.
How far should I swim on my first open water session?
Much shorter than you think: 200-400m is a good target even if you regularly swim 2km in a pool. Open water is harder: no lane lines, cold water costs energy, and navigation takes focus. Starting short and feeling good beats starting ambitious and panicking halfway across.
What is sighting, and how do I learn it?
Sighting is lifting your eyes just above the waterline every 8-10 strokes to spot a landmark and confirm your direction. Without it, most swimmers drift 20-30% further than the straight-line distance. Watch a 5-minute YouTube video on sighting technique before your first swim; it makes the session dramatically less frustrating.
