The Mares Flexa Vest She Dives is built to add warmth without making your exposure system feel bulky. Made from 100% 3 mm Ultrastretch neoprene, it layers easily under a Flexa suit, while the integrated hood and Glideskin face seal help improve comfort and heat retention on colder dives.
Product Overview
The Flexa Vest She Dives is a simple way to increase warmth when water temperatures push beyond the comfortable range of a single wetsuit alone. Built from 100% 3 mm Ultrastretch neoprene, it is meant to sit as an additional thermal layer under a scuba wetsuit, adding insulation while still allowing the flexibility needed for easy movement before and during the dive.
The integrated hood adds useful protection in one of the areas where divers lose heat fastest, and the Glideskin seal around the face is there to create a closer, more comfortable fit. Together, those details make the vest more effective than a basic sleeveless add-on, especially for longer dives, repeat dives, or cooler conditions where exposure management matters more.
For divers putting together a more adaptable cold-water setup from our range of scuba equipment, this vest is a practical upgrade that focuses on warmth, comfort, and straightforward compatibility with Flexa suits. It is best suited to wetsuit divers who want extra heat retention and hooded coverage without switching to a completely different exposure system.
