RainBlocker® Technology Waterproof, windproof, breathable technology which is impermeable to outside moisture, while allowing perspiration from the inside and dispersing it through the membrane system. Garment seams are heat sealed and secured with waterproof tape.
Thinsulate Thinsulate™ provides 1 to 2 times the insulation of duck down, while being much less water-absorbent and much more resistant to crushing. The insulation properties are beneficial for retaining some of the heat produced by the body for comfortable warmth while the moisture produced, e.g. by sweating, evaporates.
