9 Essential Gear Picks for Long-Distance Swim Events

Stepping off the shoreline into a vast expanse of open water for a long-distance swim is as much a mental challenge as it is a physical one. Unlike a controlled pool environment, the open water subjects swimmers to shifting currents, temperature drops, and relentless chafing. Having the right, specialized gear is not about luxury—it is the thin line between crossing the finish line in triumph or calling for a safety kayak rescue.

How to Gear Up for Your First Open Water Marathon

Transitioning from lane lines to open water requires a shift in how gear is selected and trusted. In a pool, a leaking goggle or a chafing suit means stopping at the wall for a quick adjustment, but miles from shore, every minor discomfort compounds into a race-ending issue. Preparing for an open-water marathon means prioritizing reliability, visibility, and thermal protection well before race day.

The golden rule of marathon swimming is to never try anything new on race day. Every piece of equipment must be thoroughly tested in simulated race conditions, including chop, wind, and varying light. Group swims and practice runs in actual open water will expose gear failures early, allowing time for fine-tuning.

Swim Goggles – Magic 5 Blue Magic Mirror Gold

Goggles in open water serve a dual purpose: keeping water out of the eyes and allowing clear sighting of buoys over long distances. Standard pool goggles often pinch or leak during hours of continuous wear, leading to eye strain and headaches. A specialized pair ensures a consistent seal despite facial movements and changing water temperatures.

The TheMagic5 Blue Magic Mirror Gold goggles utilize custom 3D facial scanning technology to construct a gasket that matches the exact contours of the swimmer’s face. This custom fit eliminates the need to over-tighten the strap, reducing pressure on the eye sockets during long-duration swims. The mirrored gold lenses are ideal for outdoor conditions, filtering out harsh surface glare while optimizing contrast to help spot buoys on sunny days.

Because these goggles are custom-made, they require using the manufacturer’s smartphone app to scan the face prior to ordering. This means they cannot be bought last-minute at an event expo and are not suitable for sharing with a training partner. They are the ultimate choice for swimmers who suffer from chronic goggle leaks or temple pressure, but are not necessary for casual swimmers who fit standard off-the-shelf options.

• Fitting Method: Custom 3D facial scan via smartphone app
• Lens Type: Mirrored, UV-protection, anti-fog coating
• Best Use: Bright sunlight, open water sighting, long-duration swims

Triathlon Wetsuit – Orca Athlex Float Wetsuit

In open water, keeping the core warm is crucial for preventing hypothermia, while maintaining an efficient body position reduces muscle fatigue. A high-quality wetsuit provides both thermal insulation and buoyancy, keeping the hips high in the water. This buoyancy allows the swimmer to save energy, which is critical during the later stages of a long-distance swim.

The Orca Athlex Float Wetsuit is designed specifically for swimmers who need improved body position in the water. It features thick Yamamoto 39-cell neoprene in the legs and torso to correct heavy leg posture, while incorporating thinner, highly elastic neoprene around the shoulders. This combination maximizes buoyancy without sacrificing shoulder mobility or causing early arm fatigue.

Getting the correct fit is critical; a wetsuit must fit tightly to prevent water from pooling inside, but not so tight that it restricts chest expansion. Putting it on takes practice, and using plastic bags over the feet and hands helps slide the limbs through the tight cuffs without tearing the neoprene. This suit is perfect for swimmers looking to improve their swim posture, but it will be too warm for waters consistently above 72°F (22°C).

• Material: Yamamoto 39 and 38-cell neoprene
• Thickness: 4.5mm on thighs/torso, 2mm on shoulders
• Target Swimmer: Swimmers needing buoyancy support and thermal protection

Safety Swim Buoy – New Wave Swim Buoy PVC 15L

Visibility is the most critical safety factor when swimming in open water shared with motorized boats, jet skis, and kayakers. A safety swim buoy acts as a bright visual marker that floats behind the swimmer, making them instantly visible from a distance. It also provides a reliable flotation source to rest on in case of cramping or panic.

The New Wave Swim Buoy PVC 15L is a lightweight, brightly colored inflatable float that tethers securely to the swimmer’s waist. The heavy-duty PVC construction is designed to withstand UV rays, salt water, and rough handling without puncturing. Its streamlined design ensures it glides smoothly behind the swimmer, creating zero noticeable drag during the stroke.

This buoy features a dry compartment to store small items like car keys, a phone, or energy gels, keeping them dry while on the water. It is important to note that this is not a life-saving flotation device and should not be used as a substitute for swimming ability. It is highly recommended for anyone training in open water, particularly in areas with active boat traffic.

• Capacity: 15 Liters
• Material: Heavy-duty PVC (polyvinyl chloride)
• Color Options: High-visibility orange, pink, yellow, and green

Anti-Chafe Lubricant – Body Glide Original Balm

The repetitive motion of swimming thousands of strokes can cause severe friction where skin rubs against skin or wet seams. Salt water amplifies this effect, acting like sandpaper on vulnerable areas such as the neck, underarms, and groin. Left unprotected, chafing can become painful enough to force a swimmer to abandon their event.

Body Glide Original Balm is a dry, non-greasy barrier that protects the skin from friction and moisture. Unlike petroleum-based jellies, which degrade neoprene and ruin expensive wetsuits, this formula is completely safe for all swimwear materials. It is highly water-resistant, staying on the skin through hours of continuous exposure to salt and fresh water.

For best results, apply the balm generously to dry skin before putting on your swim gear. It rolls on like deodorant, keeping your hands clean and grease-free so you do not lose your grip on your goggles. While excellent for preventing raw skin, it is not designed to heal existing cuts or severe sunburns.

• Formula: Allergen-free, plant-derived ingredients
• Wetsuit Safe: Yes (non-petroleum)
• Application: Roll-on stick

Neoprene Swim Cap – Blueseventy Thermal Cap

A significant amount of body heat is lost through the head, which can quickly lead to hypothermia in cold water. Standard latex or silicone swim caps offer minimal insulation once submerged in water below 60°F (15°C). A neoprene swim cap is essential for trapping a thin layer of water against the scalp, which the body warms to maintain core temperature.

The Blueseventy Thermal Cap features a Zirconium inner lining that repels water and adds an extra layer of thermal defense. The 3mm Yamamoto neoprene construction is highly flexible, ensuring a snug fit that prevents cold water from flushing through. An adjustable hook-and-loop chin strap keeps the cap secure through crashing surf and fast currents.

Sizing is critical for this cap; if it is too tight, it can cause jaw fatigue or headaches, but if it is too loose, cold water will seep in. The under-chin strap can feel restrictive at first, so practicing with it during training is highly recommended. This cap is a must-have for cold-water events but is far too warm for summer swims in temperate waters.

• Material: 3mm Yamamoto neoprene with Zirconium lining
• Closure: Adjustable hook-and-loop chin strap
• Best Use: Cold-water swimming (under 60°F / 15°C)

GPS Swim Watch – Garmin Swim 2 GPS Smartwatch

Tracking distance and pacing in open water is challenging because there are no lane lines or walls to count laps. A dedicated swim watch uses GPS to track your path, pace, and stroke rate in real time, helping you stick to a race strategy. It also records valuable data that can be analyzed later to improve efficiency.

The Garmin Swim 2 GPS Smartwatch is engineered specifically for swimmers, featuring a dedicated open-water swim mode. This mode utilizes multiple satellite systems to track swim paths even during the brief moments the wrist is out of the water. It also measures underwater heart rate directly from the wrist, eliminating the need for uncomfortable chest straps.

Because wet touchscreens are notoriously difficult to operate, the watch uses physical buttons that are easy to press mid-stroke. Keep in mind that GPS signals do not penetrate water, so the watch relies on the recovery phase of your stroke to lock onto satellites. This watch is ideal for goal-oriented swimmers, but casual swimmers may find the abundance of metrics unnecessary.

• GPS Support: GPS, GLONASS, and Galileo
• Battery Life: Up to 13 hours in GPS mode
• Water Rating: 5 ATM (50 meters)

Swim Earplugs – SurfEars 3.0 Water Sports Earplugs

Continuous exposure to cold water and wind can cause inner ear irritation, swimmer’s ear, or long-term bone growth known as “surfer’s ear.” Standard earplugs block water but also block sound, which isolates the swimmer and makes hearing safety briefs or boat traffic impossible. Specialized earplugs solve this by keeping water out while letting sound in.

SurfEars 3.0 earplugs utilize a patented acoustic mesh membrane that blocks water entry while allowing sound waves to pass through. This allows swimmers to maintain spatial awareness, hear coaching instructions, and communicate with support kayakers. The ergonomic design fits comfortably in the ear canal without causing pressure points.

The plugs come with interchangeable wings and gel tips in various sizes, allowing for a highly customized, watertight fit. An integrated leash is included to prevent losing them in rough water if they happen to dislodge. They are an excellent investment for open-water swimmers, though they are significantly more expensive than simple silicone putty plugs.

• Acoustic Core: Patented sound-permeable mesh
• Included Accessories: 4 sizes of silicone gel tips, 2 wing sizes, storage case, leash
• Primary Benefit: Water exclusion with preserved hearing and spatial awareness

Energy Gel – GU Energy Original Nutrition Gel

During swims lasting longer than an hour, the body depletes its stored glycogen, leading to sudden fatigue and muscle cramping. Because solid food is difficult to chew and digest while swimming, liquid or gel nutrition is the standard choice. Energy gels provide a quick, concentrated source of carbohydrates that are rapidly absorbed by the body.

GU Energy Original Nutrition Gel utilizes a dual-source carbohydrate blend of maltodextrin and fructose to maximize absorption while minimizing stomach distress. Each packet delivers 100 calories alongside essential electrolytes like sodium to prevent cramping. Added branched-chain amino acids (BCAAs) help reduce muscle tissue damage during prolonged efforts.

Consuming gels in the water requires practice, as tearing open a packet with cold, wet hands can be difficult. Swimmers must also be mindful of litter, tucking empty packets securely inside their wetsuit sleeve or safety buoy. These gels are highly effective for sustaining energy, but they should always be consumed with a swallow of water to prevent dehydration and aid digestion.

• Calorie Count: 100 calories per packet
• Carbohydrate Source: Maltodextrin and Fructose
• Key Electrolytes: Sodium and Potassium

Microfiber Towel – Nomadix Original Towel

After spending hours in cold water, getting warm and dry as quickly as possible is essential for preventing post-swim shivering. Standard cotton towels are bulky, absorb moisture slowly, and stay wet for hours, making them difficult to pack in a swim bag. A high-performance microfiber towel solves this by offering high absorbency in a compact package.

The Nomadix Original Towel is made from post-consumer recycled plastic bottles, resulting in a durable, eco-friendly fabric. It absorbs four times its weight in water and dries four times faster than traditional cotton, making it ready to pack shortly after use. The tightly woven fibers naturally repel sand, dirt, and pet hair, keeping your gear bag clean.

Microfiber has a different texture than plush cotton, requiring a patting motion rather than vigorous rubbing to dry the skin. It packs down to a fraction of the size of a standard bath towel, saving valuable space for bulky items like wetsuits. This towel is an excellent choice for swimmers who travel to events or have limited gear storage space.

• Material: 80% Recycled Polyester, 20% Nylon
• Dimensions: 30″ x 72″
• Special Feature: Slip-resistant, sand-resistant, quick-drying

How to Manage Hydration and Nutrition on the Water

Staying hydrated during a long-distance swim is challenging because there is no easy place to set down a water bottle. Swimmers must coordinate their feeding schedule with a support boat or kayaker, or carry nutrition inside their safety buoy. Feeds should be quick and efficient, spaced every 30 to 45 minutes, to keep energy levels stable before a crash occurs.

Cold water can mask sweat loss, making it easy to forget that hydration is just as important in the water as it is on land. Electrolyte-rich fluids should be consumed at ambient temperature; ice-cold drinks can shock the stomach and lead to cramping. Practice taking fluids while treading water during training to keep your heart rate under control and avoid swallowing lake or ocean water.

How to Wash and Store Your Open Water Swim Gear

Salt water, chlorine, and lake silt are highly corrosive and will degrade expensive swim gear if left unchecked. The absolute first step after any swim is to thoroughly rinse all equipment in clean, fresh water. Wetsuits should be washed inside and out, then hung to dry on a thick, padded hanger to prevent creasing in the shoulders.

Always store goggles in their protective case to prevent scratches on the mirrored coating, and never wipe the inside of the lenses, as this destroys the anti-fog treatment. Neoprene accessories like caps, booties, and gloves must be completely dry before storage to prevent mold and mildew growth. Keep all gear stored out of direct sunlight, as UV rays rapidly break down synthetic rubbers and plastics.

Equipping yourself with specialized, reliable gear is the most effective way to ensure safety and comfort during long-distance swim events. By choosing high-quality equipment and testing it thoroughly before race day, you eliminate unnecessary distractions on the water. With your gear dialed in, you can focus entirely on your rhythm, your pacing, and the open water ahead.
