Why We Like The Wind River Sleeping Bag:

The Wind River Sleeping Bag from Marmot is our top choice for cold weather camping. Whether you're camping in the shoulder seasons, at higher altitudes, or even during the winter, this mummy bag is perfect. It is filled with 650-fill down that efficiently traps body heat, keeping you warm and comfortable throughout the night. The down is also treated with Down Defender, which ensures that it retains its insulation even in damp conditions. Plus, the baffle construction minimizes gaps, preventing cold spots and ensuring thorough insulation.
