Overview
Pteromy's sleeping bag runs a 50-80F comfort range with a 40-90F limit, built from a water-resistant, windproof shell over Hollowfiber cotton fill, and stretches to 220cm to fit adults up to 6-7 feet tall.
The double S-shaped stitching pattern is the detail worth noting, since it is what keeps the fill from clumping into cold spots through machine washing, a common complaint on cheaper cotton-fill bags. At 1.35kg it is among the lighter bags in this set, and the inner Velcro pocket is a small but genuinely useful add for keeping a phone or headlamp within reach overnight.
- Length 220cm (7 ft 2 in)
- Hollowfiber cotton fill
- Comfort range 50-80F
- Includes compression bag
Who it's for
Suits taller campers, up to 6-7 feet, who want a washable warm-weather-to-mild-fall bag with a low pack weight. Less suited to anyone expecting cold-weather protection, since the 40F limit is the floor, not the comfort point.
Pros and cons
- Fits adults up to 6-7 feet tall
- Machine washable without fill clumping
- Weighs about 1.35 kg packed
- Inner Velcro pocket for small items
- Comfort floor is 50F, not for cold nights
- Water resistant only, not fully waterproof
- No stated shell material name
Performance notes
Double S-shaped stitching locks the Hollowfiber cotton fill into channels so it keeps its loft and thermal efficiency even after repeated machine washing, addressing the clumping plain-quilted bags develop over time. The bottom zipper opens for quick venting when the 50-80F comfort band runs warm, and the drawstring hood seals the head end when it runs cool.
