Hevto Men Wetsuits 3/2mm Back Zip Fullsuit
Best for: Cold-water swimmers and extended water sessions where back-entry is preferred. This 3/2mm fullsuit offers warmth and buoyancy that helps conserve energy during longer swims or water sports. It features an upgraded tank zipper puller to simplify on/off, reducing hassle between sets.
Why selected: The back-zip design balances insulation with a backward-compatible entry for ease of use. Suitable for surfing, swimming, snorkeling, and diving, it provides wind and sun protection while maintaining flexibility in the torso and limbs.
Caution: A back-zip wetsuit may take slightly longer to zip up for first-time users and can be less water-entry-tight than some front-zip models if not sealed properly.
Hevto Men Wetsuits 3/2mm Neoprene Front Zip Full Wet Suit
Best for: Swimmers who prioritize quick entry and exit. The front-zip design makes it easier to put on and take off, especially after practice or beach days with changing rooms. The 3/2mm neoprene delivers similar warmth to the back-zip variant while offering a different zipper experience.
Why selected: It covers the same core warmth and flexibility as the back-zip, with added convenience for users who prefer top-entry suits during fast transitions between swimming sessions or activities like snorkeling and paddleboarding.
Caution: Front-zip suits can be slightly less water-entry-tight around the zipper area if the seal isn’t properly maintained after multiple uses.

Best for: Women seeking a tailored fit for chilly water activities like surfing, snorkeling, and diving. The 3/2mm wetsuit balances warmth with flexible movement and a distinct rose-red aesthetic for visibility and style in the water.
Why selected: The feminine cut paired with a long sleeve and chest warmth supports longer sessions in cooler water, while the vibrant color improves visibility for safety in open water contexts.
Caution: Availability may vary by size; verify the size chart to ensure a snug fit for warmth and heat retention.
Seaskin Mens 3mm Shorty Wetsuit
Best for: Warm-weather waters and water-sport activities where freedom of movement is prioritized. The shorty design with a front zip helps swimmers, divers, and surfers stay warm without bulk in milder conditions.
Why selected: The combination of 90% neoprene and 10% nylon provides stretch and heat insulation with a flexible fit. It suits beginners and experienced swimmers who want a compact wetsuit for mixed-water use.
Caution: Shorty suits may provide less insulation in very cold water and are less protective for full-body exposure in cooler seasons.

Best for: Swimmers who want durability and warmth with easy access. The 3/2mm full suit features a back zipper, chest protection for warmth, and reinforced knee pads for rough surfaces.
Why selected: The back-zip design paired with a durable outer and reinforced knee pads makes it a robust option for regular use in surf or dive environments. It offers a balance of warmth and flexibility for longer sessions.
Caution: Back-entry suits can be slightly slower to zip up for first-time users; ensure proper sealing to minimize water entry around the zipper.
Buying Guide: Thin Wetsuit For Swimming
What should you consider when choosing a thin wetsuit for swimming?
- Water temperature and water activity: For mild to cool waters, a 2/3mm or 3/2mm wetsuit provides core warmth without excessive bulk. Shorties suit lighter activities or hot days.
- Entry style: Front-zip offers easier on/off, back-zip can be more watertight and streamlined, while easy-entry designs help during frequent transitions.
- Fit and flexibility: Look for wetsuits that describe a snug, close-to-body fit to maximize heat retention. Ensure freedom of movement for your arms and shoulders.
- Coverage and protection: Long sleeves and full-body coverage improve warmth and protection against sun, jellyfish, and abrasions. Shorties emphasize mobility.
- Durability: Reinforced knees and robust seams (flatlock or blind-stitched) extend the life in active water sports.
- Care and maintenance: Rinse with fresh water after use, dry away from direct heat, and inspect zippers and seams regularly to maintain performance.
