The Thermal Backpacker was explicitly created for rugged outdoor activity in the fall and winter. The blend of merino and acrylic makes this sock warm and soft while able to wick moisture. In addition, its mid-weight cushioning throughout adds a layer of protection and support for your feet during long hikes. 

Why we use merino wool in our socks:
Merino wool is a type of wool that comes from a merino sheep. It is the finest wool on the market, making the fabric soft and itch-free. It is also breathable and temperature-regulating, so your feet are not too hot or cold. Merino is one of the best fibres for wicking moisture as it can absorb up to 30% of its weight in moisture and moves it from your skin to the outside of the fabric, where it evaporates. Because it stays dry, odour-causing bacteria cannot grow, making it a naturally antimicrobial fibre.

Sizes available:
Medium (Women's 5-9 Shoe / Men's 4-8 Shoe)
Large (Men's 8-12 Shoe / Women's 9 -13 Shoe)
