Common questions
Borderline fittersEach arm hole has an inner flap that closes over it when you are not using it. With your arms out, your body stays inside the bag with the hood and collar closed, so you lose far less heat than by unzipping.

Questions
Asked in store, answered by our fitters
Do the arm holes let cold air in?
Each arm hole has an inner flap that closes over it when you are not using it. With your arms out, your body stays inside the bag with the hood and collar closed, so you lose far less heat than by unzipping.
PS300 or PS500?
PS300 (comfort 3.9 °C) for September nights and warm sleepers; PS500 (comfort −1.9 °C) for October, for cold sleepers, or if you plan to sit around camp in it after dark. The PS500 is about 1 kg heavier and noticeably thicker.
Can I walk around in it?
It is designed for sitting and lounging at camp with your hands free: make coffee, read, use your phone without unzipping. You can shuffle a few steps, but it is a sleeping bag, not a suit.
Can two zip together?
Yes. One Gray (left zip) and one Brown (right zip); two of the same colour will not join.
How do I wash it?
Yes, it is machine washable: close the zips, use a gentle cycle and let it dry fully. Store it loose so the fill keeps its loft.
How is it different from a normal rectangular sleeping bag?
A normal bag makes you choose: warm and zipped in, or arms out and cold. This one has arm holes with flaps, a hood and a draft collar, so you sit up and use your hands while staying zipped to the chest. Same machine-washable cotton fill, same zip-together option, one extra idea that changes evenings at camp.
