Why Sherpa Is A Winter Staple:

Sherpa jackets make for an ideal winter layer, designed to provide warmth and comfort. Sherpa material is thick and has soft, fuzzy looping, which helps to trap heat near the wearer’s body. The Mammoth Sherpa Jacket also features a windproof inner polyester lining, making it a barrier for cold, wet weather.

A Year-Round Staple Piece:

Sherpa material also offers superior breathability, allowing moisture to escape and keeping you warm and dry, while also regulating internal temperature. The Mammoth Sherpa Jacket was also designed to be lightweight enough to be layered with other pieces of clothing, making it the perfect piece no matter the season.
