The key to PreCip™ is its barrier technology: a microporous polyurethane that is impregnated with silicon dioxide particles. These particles create small, numerous, very consistent holes that allow the barrier to pass small water vapor molecules but not the bigger liquid ones. This keeps the rain out while letting your sweat vapor work its way outside, away from your body, to keep you dry from the inside as well as from the outside. PreCip™ rainwear is compressible enough to stuff into a water bottle and comes in enough colors and styles to travel with you anywhere– to the mountains, the city or overseas.
