PreCip is our "next step" technology that enables us to construct the lightest, most compressible, technical, waterproof and breathable rainwear in the world. Ventilated and breathable to keep you dry from the inside, PreCip rainwear has plenty of pockets and custom fit features to keep you warm, dry and comfortable. The new PreCip coating is now more waterproof, more breathable and more comfortable to wear. We've added ceramic particles in the coating for added durability, waterproof reliability and Dry Touch comfort. 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.
