The Complete Guide to Swimming Equipment — See Clearly, Swim Better

The Three Essentials — Goggles, Cap, Swimsuit

Swimming's equipment list is mercifully short. To swim in a pool, you need three things:

Goggles — to see where you are going, protect your eyes from chlorine, and make the experience immeasurably more pleasant. You can swim without goggles. You will not enjoy it.

A swim cap — not strictly required in all pools, but strongly recommended. It keeps hair out of your face, reduces drag, and partially protects hair from chlorine damage.

A swimsuit — one that is designed for swimming rather than sunbathing. Training swimwear fits close, resists chlorine, and does not create drag.

That is the foundation. Everything else — kickboards, pull buoys, fins, paddles, snorkels — is training equipment that builds on this base. Most pools provide kickboards and pull buoys for lane swimmers to use, so you may not even need to buy your own initially.

Swim Goggles — The Purchase That Changes Everything

Goggles are the single most important swimming purchase, and the difference between a good pair and a bad pair is the difference between wanting to swim and wanting to get out.

Bad goggles leak. Water seeps in around the eye sockets, which means you spend your swim constantly adjusting them, pressing them tighter against your face, and losing your rhythm. Bad goggles fog. Within minutes, you cannot see the wall, the clock, or the person in the next lane. Bad goggles hurt. They press into the bridge of your nose or leave red rings around your eyes that last an hour.

Good goggles seal gently against your eye sockets, stay in place through tumble turns and dives, remain clear for most of your swim, and leave minimal marks when you take them off. Finding them is primarily about fit, not price.

Choosing Goggles That Actually Fit

Goggle fit is personal. Your eye socket shape, nose width, and face contour determine which goggles seal properly, and this varies enormously between people. A pair that fits one swimmer perfectly may leak on another.

The press test. Push the goggles gently against your eye sockets without using the strap. If they create a light suction and stay in place briefly on their own, the seal suits your face. If they fall away immediately or do not sit evenly, they will leak when you swim.

Nose bridge. Most goggles come with an adjustable or interchangeable nose bridge. A bridge that is too narrow pinches; too wide and the goggles sit poorly. Many mid-range goggles include multiple nose bridge sizes — this is a more useful feature than it sounds.

Strap adjustment. The strap should hold the goggles in place without excessive pressure. If you find yourself tightening the strap to stop leaks, the goggle shape does not suit your face — tighter is not the answer, better fit is.

Gasket type. The gasket is the soft material that seals against your skin. Silicone gaskets are comfortable and durable. Foam gaskets are softer but wear out faster. Racing goggles sometimes have minimal or no gaskets at all — they seal directly against the skin for a lower profile, but are less comfortable for longer sessions.

Lens size. Larger lenses provide a wider field of vision, which is helpful in open water or busy lanes. Smaller, lower-profile lenses sit closer to the face, create less drag, and are preferred by competitive swimmers. For recreational and training purposes, a medium-sized lens offers a good balance.

Anti-Fog and Lens Colour

Anti-fog coatings are applied to the inner surface of goggle lenses to prevent condensation from forming. All anti-fog coatings degrade over time — this is normal and unavoidable. Rubbing the inner lens, even to clean it, accelerates the degradation. To prolong the anti-fog life: rinse goggles with cool water after each swim, shake off excess water, and let them air dry. When the coating eventually fails, anti-fog sprays and drops can restore clarity temporarily.

Lens colour matters more than you might expect:

• Clear lenses — best for indoor pools and low-light conditions. Maximum light transmission.
• Tinted lenses (grey, smoke) — reduce glare in bright conditions. Good for outdoor pools and sunny days.
• Mirrored lenses — reflect light away from the eyes. Ideal for outdoor swimming in bright sunlight. Also popular in competition because they conceal your eye direction from competitors — a minor tactical advantage.
• Blue or amber tinted — enhance contrast in specific conditions. Amber is useful in murky open water.

For indoor pool swimming, clear or lightly tinted lenses are all you need. For outdoor swimming, darker tinted or mirrored lenses reduce squinting and improve comfort.

Swim Caps — More Useful Than You Think

Caps serve three practical purposes: keeping hair out of your face, reducing drag through the water, and providing a degree of protection against chlorine. They do not keep your hair dry — water gets under even the tightest cap — but they limit the amount of chlorine contact.

Silicone caps are the most popular. They are durable, stretchy, comfortable, and easy to put on. They come in a huge range of colours and last well with basic care.

Latex caps are thinner and cheaper but tear more easily and can trigger latex allergies in sensitive individuals. They are adequate for occasional use but less durable than silicone.

Lycra/fabric caps are the most comfortable but provide no water resistance. They keep hair tidy and reduce drag minimally. Common in recreational swimming.

For regular pool swimming, a silicone cap is the clear recommendation. They last months with proper care (rinse after use, air dry, store flat or loosely folded — never scrunch into a ball).

Swimwear — Training vs Competition

Training swimwear is designed to withstand chlorine, fit closely, and last. Chlorine degrades fabric, so training suits use chlorine-resistant materials (polyester blends or PBT) that maintain their shape and colour far longer than fashion swimwear. A good training suit should last three to six months of regular use.

For women, one-piece training suits are the standard for lap swimming. They provide coverage, support, and minimal drag. For men, jammers (knee-length fitted shorts) or briefs are both common. Loose swim trunks create significant drag and are not ideal for training, though they are fine for casual swimming.

Competition swimwear (tech suits) is engineered for speed — compressive, water-repellent, and designed to be worn for races rather than daily training. Tech suits are fragile and expensive. Unless you compete, you do not need one.

Kickboards

The kickboard is the most familiar piece of swim training equipment. You hold it at arm's length and kick, isolating your legs while the board supports your upper body.

Kickboards build leg strength and endurance, improve kicking technique, and provide variety in training sessions. Most pools have kickboards available for lane swimmers, so buying your own is optional unless you want a specific size or style.

Standard kickboards are made from closed-cell EVA foam — lightweight, durable, and buoyant. Smaller boards provide less support and require more core engagement, making them more challenging. Larger boards are easier and suit beginners or recovery work.

Pull Buoys

A pull buoy is a figure-eight-shaped foam float that you hold between your thighs. It lifts your hips and legs to the surface, eliminating the kick and isolating your arm stroke.

Pull buoys are excellent for building upper body strength, improving arm technique, and teaching you what good body position feels like. Many swimmers find they are significantly faster with a pull buoy, which reveals how much their legs are dragging them down — useful and humbling in equal measure.

Pull buoys are inexpensive and last for years. If your pool does not provide them, owning one is a small investment with significant training value.

Training Fins

Swim fins (short training fins, not full-length snorkelling fins) increase the surface area of your kick, building leg strength and allowing you to practise drills at higher speeds than you could achieve without them.

Short fins with a flexible blade are the standard for pool training. They encourage a fast, compact kick and do not put excessive strain on the ankles. Long fins — the type used in snorkelling — are too slow and cumbersome for pool training.

Fins are particularly helpful for learning butterfly kick, improving body position, and adding speed to drill work. They are also genuinely fun — swimming fast with fins provides a taste of what better technique feels like.

Sizing: Fins should fit your bare foot snugly. Too loose and they rub; too tight and they cramp. Most brands provide sizing guides, and getting this right matters more than with most equipment.

Hand Paddles

Paddles increase the surface area of your hands, adding resistance to every stroke and building upper body strength. They also magnify any flaws in your technique — a bad hand entry with paddles becomes immediately and uncomfortably obvious, which makes them a useful feedback tool as well as a strength builder.

Start with small paddles. Oversized paddles put significant stress on the shoulders, and using them before your technique is solid risks shoulder injury. Many experienced swimmers use finger paddles or medium-sized paddles for most training and only reach for large paddles for specific strength sets.

Paddles are not beginner equipment. Develop a solid freestyle stroke before introducing them, and if you experience any shoulder discomfort while using paddles, stop.

Centre-Mount Swim Snorkels

A swim snorkel sits in front of your face (not to the side, like a snorkelling snorkel) and allows you to breathe continuously while swimming. This removes the need to turn your head to breathe, freeing you to focus entirely on your stroke mechanics, body position, and balance in the water.

Swim snorkels are excellent for technique work. Without the disruption of breathing to one side, you can feel imbalances in your stroke, work on symmetry, and maintain a steady head position. They are also useful for recovery swimming, allowing you to move gently without the physical effort of bilateral breathing.

Ear Plugs and Nose Clips

Ear plugs are worth considering if you are prone to ear infections, discomfort from water in the ears, or the condition known as swimmer's ear. Mouldable silicone plugs provide a good seal and are comfortable for extended use. Some are specifically designed for swimming rather than general noise reduction — these tend to seal better against water.

Nose clips prevent water from entering the nose. They are useful for backstroke, when water can flow into the nostrils during the stroke, and for some swimmers who find water up the nose uncomfortable or distracting. Nose clips are inexpensive and entirely a matter of personal comfort — some swimmers swear by them, others find them unnecessary.

Swim Bags

A mesh or ventilated swim bag keeps your wet equipment together and allows it to air dry between sessions. Pool-going swimmers accumulate gear quickly — goggles, cap, pull buoy, fins, paddles — and a dedicated bag keeps everything organised and reduces the risk of forgetting something poolside.

Mesh bags dry fastest and prevent mildew. Backpack-style swim bags with waterproof compartments suit swimmers who travel to the pool by foot or public transport.

Open Water Swimming Equipment

Open water swimming introduces additional considerations that pool swimming does not:

Brightly coloured swim caps — visibility is a safety essential in open water. Neon pink, orange, or yellow caps ensure that you can be seen by other water users, safety boats, and people on shore.

Tow floats — inflatable buoys tethered to your waist. They provide visibility and, in an emergency, something to hold onto and rest on. Most open water swimming groups strongly recommend or require tow floats.

Wetsuits — covered in detail in our wetsuits guide. Open water temperatures often require thermal protection.

Anti-chafe products — salt water and prolonged swimming can cause chafing at the neck, under the arms, and where swimwear edges sit. Petroleum jelly or purpose-made anti-chafe balm prevents this.

Children's Swimming Equipment

Children need the same essentials as adults — goggles, a cap (optional but helpful), and a swimsuit — but sizing and comfort matter even more because an uncomfortable child will not want to swim.

Goggles are the priority. Children's goggles should seal comfortably, adjust easily, and have a strap that does not pull hair. Let the child try them on and do the press test. If the goggles hurt, they will not be worn.

Swimwear should be chlorine-resistant if the child swims regularly. Fashion swimwear degrades quickly in pool water.

Buoyancy aids (arm bands, float vests, swim noodles) are separate from swimming equipment and relate to water safety rather than swimming training. They should always be appropriate for the child's age, weight, and swimming ability, and should never replace adult supervision.

Choosing Equipment for Your Level

The Honest Limitations

Equipment does not teach you to swim. Fins, paddles, and snorkels improve an existing stroke — they do not create one. If you are learning, lessons from a qualified instructor are worth infinitely more than any piece of equipment.

Pool equipment varies. Most pools provide kickboards and pull buoys. Some provide fins and paddles. Check what is available before buying your own — you may already have access to everything you need.

Goggles are consumables. No pair of goggles lasts forever. The anti-fog coating degrades, the silicone gasket hardens, and the strap loses elasticity. Expect to replace goggles every four to six months with regular use.

Tech suits are not for training. Competition swimwear is designed for race-day performance and deteriorates rapidly with regular use. Training in a tech suit is an expensive way to ruin it.

Common Mistakes Buyers Make

Buying goggles without testing the seal. The press test takes five seconds and tells you everything you need to know. Goggles that do not seal on dry land will not seal in the water.

Rubbing the inside of goggle lenses. This destroys the anti-fog coating. Rinse with water, shake dry, and leave them alone.

Buying full-length snorkelling fins for pool training. Pool training fins are short-bladed. Long fins are for open water and snorkelling — they are too cumbersome for pool drills and can strain the ankles.

Skipping the swim cap. Caps protect your hair from chlorine, keep it out of your face, and reduce drag. For the tiny cost, there is no good reason not to wear one.

Using paddles too soon. Paddles amplify whatever your stroke is doing — good and bad. If your technique has flaws, paddles will stress your shoulders. Build a solid stroke first.

Your Pre-Purchase Checklist

Do Your Goggles Seal?

Use the press test. If they do not create a light suction against your eye sockets without the strap, they will leak.

Is Your Swimwear Chlorine-Resistant?

Regular swimwear degrades rapidly in chlorinated water. If you swim weekly or more, invest in training-grade swimwear.

Do You Actually Need Your Own Training Equipment?

Check what your pool provides. Many pools have kickboards, pull buoys, and even fins available for lane swimmers.

If Buying Fins, Are They the Right Type?

Short-bladed training fins for pool use. Not long snorkelling fins.

If Buying for a Child, Have They Tried the Goggles?

Comfort and fit matter more for children than for adults. An uncomfortable pair will put them off swimming.

Why Buying Through Amazon Makes Sense

Swimming equipment is lightweight and inexpensive to ship, making Amazon's pricing and delivery particularly competitive. The range of goggles alone runs into hundreds of models, giving you far more choice than a typical sports shop. Customer reviews are especially helpful for goggles, where fit varies so much between individuals — finding a model that others with similar face shapes recommend is genuinely useful.

Swimming asks very little of your equipment and a great deal of your willingness to get in the water. The goggles just make sure you can see where you are going while you do it.
