Why We Like The Bison GORE-TEX INFINIUM Sleeping Bag

When it comes to extreme expeditions, the Bison GORE-TEX INFINIUM Sleeping Bag is our top choice. It is rated down to -40F, making it a reliable companion in the harshest conditions. With its fully windproof design, this bag provides excellent insulation and protection.

What sets this sleeping bag apart is its exceptional fill power of 850+. This is achieved through strategically placed network of horizontal baffles, side baffles, draft tubes, and an oversized hood with ruff. This ensures optimal heat retention and blocks out the elements.
