Overview
Teton's Celsius is a regular-size mummy-hooded sleeping bag offered with 25F, 20F or 0F insulation options, built with a poly-flannel lining for camping trips spanning mild to genuinely cold nights.
The half-circle mummy-style hood is meant to trap warmth around the head and keep a pillow clean rather than wrapping the whole body like a true mummy bag. Double-layer construction and draft tubes are the parts doing the work of keeping cold air from sneaking in through seams and the zipper, and a stuff sack is included for packing it down.
- 25F, 20F and 0F rating options
- Half-circle mummy-style hood
- Double-layer draft tube construction
- Stuff sack included
Who it's for
Fits campers who want to pick a warmth level, 25F, 20F or 0F, to match their trip rather than buying separate bags for each season. Less suited to anyone wanting a true tapered mummy bag, since the hood is only half-circle rather than a full wrap.
Pros and cons
- Choice of 25F, 20F or 0F insulation ratings
- Half-circle hood keeps a pillow clean
- Stuff sack included for packing
- Room to spread out inside the bag
- Half-circle hood is not a full mummy wrap
- No stated bag weight for backpacking comparison
- Needs a separate ground pad for real cold
Performance notes
Draft tubes along the zipper and the double-layer shell are the standard defenses against the cold air that typically leaks in at the closure, and the poly-flannel lining is there for a soft feel against skin rather than for extra warmth on its own. Teton also recommends an insulated ground pad underneath, since a bag's fill does little against heat lost straight down into cold ground.
