Why Sun Protection Matters in Open Water
When you are out in the middle of a lake or bay, you aren’t just dealing with direct sunlight; you are contending with high-intensity UV rays reflecting off the water’s surface. This "double exposure" can lead to severe sunburns on your back, shoulders, and neck—areas that are constantly exposed as you rotate to breathe.
Think of your wetsuit as your primary piece of "off-grid" protective equipment. Just as you would insulate a tiny home to regulate internal temperature, a wetsuit creates a necessary barrier between your skin and the elements. Relying solely on sunscreen is a losing battle, as the water quickly washes away even the most expensive water-resistant formulas.
Orca Openwater Core: Best Full-Coverage Suit
If your primary goal is maximum skin coverage, the Orca Openwater Core is the gold standard. It features high-visibility orange panels that keep you safe from boat traffic, but the real benefit is the full-sleeve design that shields your arms and shoulders from relentless UV rays.
This suit is built for endurance swimmers who spend hours in the water and need a reliable, no-nonsense barrier. It isn’t the fastest suit on the market, but it is incredibly durable and holds up well against the wear and tear of salt water. If you prioritize protection over raw speed, this is the suit you want in your gear bag.
ROKA Maverick Pro II: Top Thermal Protection
The ROKA Maverick Pro II is a masterclass in material engineering, utilizing premium neoprene that offers exceptional buoyancy and warmth. While its primary claim to fame is its hydrodynamics, the thick, high-quality material provides a robust physical shield against the sun.
This suit is an investment piece, designed for serious athletes who need to maintain core temperature in cooler, exposed waters. The fit is precise, almost like a second skin, which minimizes water entry and ensures your covered areas stay protected throughout your swim. If you are training for long-distance events where conditions shift rapidly, this is the reliable choice.
Zone3 Advance Wetsuit: Best for Beginners
If you are just starting to transition from the pool to open water, the Zone3 Advance is the perfect entry point. It balances affordability with essential features, offering enough thickness to protect your skin from the sun without making you feel restricted or overheated.
The flexibility in the shoulders is surprisingly good for a suit at this price point, meaning you won’t suffer from shoulder fatigue during longer sessions. It’s a practical, "no-frills" tool that gets the job done without requiring a massive budget. For those just testing the waters of open water swimming, this is your best starting point.
Blueseventy Fusion: Best for Versatility
The Blueseventy Fusion is the "all-terrain vehicle" of the wetsuit world, designed to perform well across a wide range of water temperatures and conditions. Its construction focuses on a balanced buoyancy profile, which helps keep your body in a natural, flat position in the water.
Because it is so versatile, it’s an excellent choice if you only want to own one suit for the entire season. The neoprene thickness is consistent, providing reliable sun protection for your torso and arms, whether you are swimming in a calm lake or a choppy bay. It’s a dependable, middle-of-the-road option that rarely disappoints.
TYR Hurricane Category 1: Durable Choice
Durability is the hallmark of the TYR Hurricane Category 1. It features a slick skin neoprene that is resistant to the nicks and scrapes that often happen when entering or exiting rocky shorelines or climbing onto docks.
This suit is built for the swimmer who treats their gear like a tool rather than a luxury item. It offers solid UV protection and a comfortable, forgiving fit that doesn’t pinch or bind during long swims. If your local swimming spot involves tricky entries or exits, you need this level of ruggedness.
Huub Aegis III: Best for Flexibility
The Huub Aegis III is designed for the swimmer who feels constricted by traditional, thicker wetsuits. Its unique cut prioritizes freedom of movement in the shoulders, allowing for a natural, high-arm recovery stroke that feels almost like swimming in a swimsuit.
Despite this focus on flexibility, it doesn’t sacrifice the protection you need. It provides a full-coverage shield against the sun while allowing you to maintain your technique without fighting the material. If you are a swimmer who values comfort and range of motion above all else, this is the suit for you.
Xterra Volt Sleeveless: Best for Warm Days
Sometimes the water is warm enough that a full-sleeve suit feels like overkill, but you still need protection for your torso. The Xterra Volt Sleeveless is the perfect solution for those mid-summer days when you want to stay cool while keeping your core shielded.
While it leaves your arms exposed, it provides excellent buoyancy and sun protection for your chest and back. It’s an essential piece of kit for swimmers who struggle with overheating in full suits. Just remember to apply high-quality, reef-safe sunscreen to your arms before you head out.
Selecting the Right Thickness for Your Swim
Choosing the right thickness is a classic trade-off between warmth, buoyancy, and flexibility. A 3/2mm suit (3mm in the chest, 2mm in the limbs) is generally the sweet spot for most open water swimmers, offering a balance of protection and freedom of movement.
- 2mm or less: Best for warm water; offers maximum flexibility but minimal thermal or buoyancy benefits.
- 3/2mm: The versatile standard; provides a good barrier against the sun and cool water without feeling bulky.
- 4/3mm or thicker: Reserved for cold water; provides maximum warmth but can feel restrictive if you aren’t used to the added bulk.
Essential Care for Your Wetsuit Longevity
A wetsuit is a piece of precision gear that demands proper maintenance to last more than a single season. Always rinse your suit with fresh, cool water immediately after every swim to remove salt, chlorine, and organic debris.
Never leave your suit drying in direct sunlight, as the UV rays that the suit protects you from will eventually degrade the neoprene and cause it to crack. Hang it in a cool, shaded, and well-ventilated area using a wide-shoulder hanger. Treat your gear with respect, and it will keep you protected for hundreds of miles of swimming.
Finding the right wetsuit is about balancing your specific swimming environment with the realities of your own comfort and technique. Whether you choose a high-performance full-sleeve suit or a flexible sleeveless model, the goal is to keep your skin safe so you can keep swimming longer. Invest in the right gear, care for it properly, and you’ll have a reliable partner for every open water session ahead.
