Drybase - Ultra-Fast Wicking Baselayer

Cotton holds perspiration and moisture next to the skin where it can feel clammy, cold and uncomfortable. Drybase is the 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.

Drybase

A base layer next to the skin makes sense for more reasons than performance during the dive. Wear the base layer under your regular clothing on the way to the dive site, and you won’t have to strip off completely prior to getting kitted up. You will stay warmer during preparation for the dive and getting dressed will take less time. Perspiration or moisture from suit leaks will be wicked away from the skin by the base layer, making getting out of your drysuit after the dive a warmer, more comfortable experience also.
