Many divers wear cotton t-shirts or similar items underneath their undersuits and this may actually leave them feeling colder and less comfortable than diving without. Cotton holds perspiration and moisture next to the skin where it can feel clammy, cold and uncomfortable.
Drybase is the new high wicking underwear system for drysuit diving from Fourth Element. Using ultra fast wicking fabric, the Drybase garments are the ideal alternative to cotton underneath a thinsulate or other undersuit. The garments' exceptional wicking performance means that the skin is kept dry and the wearer is much more comfortable during and after the dive, and is able to get the most out for the performance of their undersuit.
With pillar valve o-rings used in place of buttons, this top has a subtle diving theme, yet looks good and is a great next to skin layer beneath any undersuit.
