SWTMERRY Sleeping Bag 3-4 Seasons 41–77℉

A versatile sleeping bag built for cooler conditions and four-season convenience, the SWTMERRY 3-4 Seasons model suits campers, hikers and families who need a compact, easy-care option. It balances weather resistance with lightness, making it simple to pack for backpacking trips or keep in the car for emergencies.

Highlights

This sleeping bag is rated for a temperature range of 41–77℉ 5–25℃ with a comfort band of 50–68℉ 10–20℃ according to the manufacturer. It uses a double-fill construction to trap warmth while a waterproof 210T nylon outer helps fend off damp and wind. The lining is 190T polyester pongee and the fill is 100% hollow fibre, which keeps the weight down and allows machine washing for straightforward cleaning. The bottom zipper design permits some foot ventilation when needed.
