Overview
A summer backpacker packing light gets the Bishop Pass, a down mummy sleeping bag with a nylon ripstop shell and a DWR treatment. A down-filled gasket and a full-length draft tube seal the zipper side.
The down fill compresses easily and gives warmth for its weight, and the mummy shape holds heat in. The limitation is range: the listing calls it a summer bag, and the mummy cut is not roomy for restless sleepers.
Who it's for
Backpackers and summer campers who prize pack space and weight will see the down fill and ripstop shell as the point. Winter campers, tall users beyond the height guide and anyone who dislikes mummy shapes should look elsewhere.
Pros and cons
- Down fill compresses well
- Mummy shape retains heat
- Draft tube along the zipper
- Glow-in-the-dark zipper pull
- Summer season rating only
- Left zip only in this listing
- Mummy cut is snug
- Packed size not listed
Performance notes
Down loft traps warm air, and fill power describes how much loft each ounce provides. The mummy shape cuts empty space around the body, and the draft tube and gasket block cold air at the zipper. DWR treatment sheds light moisture but does not make the insulation waterproof.
