The Mountain Hardwear Bishop Pass Sleeping Bag is the bag that does it all, whether we're backpacking in the Cascade Range late into the fall or setting up a winter campsite in the High Peaks of the Adirondacks. Built to extend our camping season to any time the temperatures are still positive, the lofty 650-fill down keeps us insulated from chilly weather with the help of a full-length draft tube and cozy draft collar that minimize heat loss in the coldest conditions. The lightweight, packable design gives us the freedom to backpack through the colder months so we can enjoy having the trails and campsites to ourselves.
