From first paddle to final wave, the right wetsuit helps you stay warmer, move easier, and spend more time in the water. Whether you’re heading out for a cool-weather surf session, a mellow spring paddle, or a sunny warm-water swim, this ROXY wetsuit guide breaks down how to choose the right women’s wetsuit by thickness, fit, coverage, technology, and care.
What Wetsuit Thickness Do I Need?
The best wetsuit thickness depends on the water temperature, wind, season, session length, and how quickly you get cold. As a general ROXY guide, colder water calls for thicker neoprene through the body, while warmer water allows for lighter, more flexible coverage.
What Do Wetsuit Thickness Numbers Mean?
Wetsuit thickness is measured in millimeters. The first number usually refers to the thicker material around the torso, where warmth matters most. The second number refers to the thinner material through the arms and legs for easier movement. In a three-number wetsuit, the numbers separate torso, legs, and arms.
A 5/4/3mm wetsuit combines 5mm at the torso, 4mm at the legs, and 3mm at the arms. A 4/3mm wetsuit uses 4mm through the torso and 3mm through the arms and legs. A 3/2mm wetsuit offers 3mm core warmth with 2mm flexibility through the limbs. A 2/2mm wetsuit is made with 2mm material throughout for lighter coverage in warmer water.
Choose Your Wetsuit By Coverage
Full Suit
A full suit gives you the most coverage, extending to the wrists and ankles. It’s the best choice for colder water, longer sessions, and surf days when you want more warmth from paddle-out to shore break.
Best for: cold water, winter surf, windy conditions, longer sessions
Shop for: 5/4/3mm, 4/3mm, and 3/2mm full suits
Spring Suit
A spring suit gives you balanced coverage without the full-body warmth of a winter wetsuit. It’s made for mild temperatures, warmer surf days, and relaxed movement in and out of the water.
Best for: mild water, spring surf, beach days, warm-weather paddling
Shop for: 2/2mm spring suits and short-sleeve wetsuits
Shorties, Janes, Tops & Bottoms
For warm water and sunny sessions, lighter wetsuit styles give you coverage where you want it without weighing you down. Shorties, Long Janes, Short Janes, jackets, tops, and bottoms are easy to layer with swim and made for freedom of movement.
Best for: warm water, tropical surf, SUP, swimming, sun-to-surf coverage
Shop for: 2/2mm styles, wetsuit tops, jackets, bottoms, and shorties
How Should a Women’s Wetsuit Fit?
A wetsuit should feel snug, smooth, and close to the body, almost like a second skin. It should not feel painfully tight, but it also should not leave loose pockets where water can pool. A proper fit helps reduce flushing, which happens when cold water moves freely through the suit.
When trying on a wetsuit, check for:
- No extra room around the lower back, crotch, shoulders, knees, wrists, or ankles
- No bunching at the arms or legs
- A secure neck, wrist, and ankle seal
- Enough mobility to lift your arms, bend, stretch, and mimic a paddling motion
- A snug dry fit, knowing neoprene relaxes slightly once wet
If the suit feels slightly tight on land but still lets you move comfortably, that’s usually a good sign. If it makes it hard to breathe, raise your arms, or paddle naturally, it may be too small. ROXY’s own fit guidance also emphasizes checking for extra room, testing paddling movement, and remembering that neoprene stretches when wet.
Wetsuit Entry Systems: Back Zip vs. Front Zip
The best choice depends on what matters more to you: easy changing, extra mobility, or a more secure water seal.
Back Zip Wetsuits
Back zip wetsuits are designed for easier entry and exit. The zipper runs down the back, making them simple to pull on and take off, especially for newer surfers or anyone who wants a more familiar fit.
Front Zip Wetsuits
Front zip or chest zip wetsuits are designed with the entry point across the chest. This can help reduce water entry compared with some back zip constructions, but it may take more effort to get in and out of the suit.
How to Care for Your Wetsuit
A little care goes a long way. After every surf, rinse your wetsuit in fresh cold water to remove salt, sand, and dirt. Rinse both the inside and outside, then let it dry in the shade.
To help protect your wetsuit:
- Rinse with fresh cold water after each use
- Avoid hot water, washing machines, dryers, bleach, and direct heat
- Dry inside-out first, then turn it right-side out
- Keep it out of direct sunlight while drying
- Use a wide hanger or fold over a hanger at the waist
- Avoid wire hangers, which can crease or stress the suit
- Do not leave your wetsuit in a hot car for long periods
Sustainably Built
