Shiver Shield is THE leader in lightweight, thin, and extremely warm outdoor gear. Our clothing and accessories use a proprietary, high-tech insulation which keeps you warm even at the most extreme temperatures.

Aerogel insulation was developed in 1930, but due to its composition, it took the better part of a century and much research to get it to the point where it could be used in clothing. Because it's just a few millimeters thick, the insulation provides minimal bulk and maximum comfort. Combine that with no need for additional layers and you have the perfect formula to stay warm without the bulk.

Shiver Shield's Men’s Prym1 White Out Pants are extremely thin with wind and waterproof insulation. Machine Wash/Dry. Lifetime Warranty on Manufacturing Defects.
