Warmth Built for Every Freedive

What factors matter most when choosing a freediving wetsuit?

Choosing the right freediving wetsuit comes down to thickness, construction, and how much warmth you need. Lighter suits like the Tokugawa Nylon 3mm work for warm water and shorter sessions, while thicker options like the Seppia 7mm hold in heat during longer, colder dives. Open-cell designs like the Tokugawa Open Cell w/Hood grip tighter against the skin for less water flushing, though they take more care to put on. Whether you choose a one-piece or two-piece style, match the thickness to your typical water temperature and dive time.

Can you freedive with a surf wetsuit?

A surf wetsuit is not ideal for freediving. Surf wetsuits use nylon-lined neoprene built for durability and repeated paddling, which traps water and adds drag with every kick. Freediving wetsuits like Cressi's open-cell designs use bare neoprene against the skin, creating a tighter seal that holds in warmth and reduces water flushing. Open-cell suits are also more flexible through the chest and shoulders for a full breath before diving. A surf wetsuit will keep you warm at the surface, but it works against you once you start diving down.
Are custom-fit wetsuits worth it for freediving?

True custom-fit wetsuits are not necessary for most freedivers, but getting the right fit absolutely matters. Cressi's open-cell freediving wetsuits, like the Seppia and Lampuga lines, rely on a snug, second-skin fit to trap a thin layer of water against your body and hold in warmth. A suit that is too loose lets cold water flush through with every kick, while one that is too tight restricts the deep breath you need before a dive. Checking Cressi's size chart before buying matters more than paying extra for a custom suit.
