Price evolution
Product description
Designed with three to four season use in mind, this SWTMERRY sleeping bag suits cool spring mornings through colder autumn nights. It blends lightweight portability with weather resistance, making it a practical choice for hiking, backpacking and general outdoor use. The rated range is 41–77°F according to the manufacturer, and the comfort zone sits between 50–68°F, so it works across a broad span of temperatures.
Key features
The sleeping bag uses double-filled construction to trap warmth while the outer 210T nylon shell offers water resistance for damp conditions. Inside, a 190T polyester pongee lining aims to feel soft against skin and the 100% hollow fibre fill keeps the insulation lofty yet machine-washable, which helps with easy maintenance. A separated bottom zipper allows ventilation and gives space for feet to emerge without letting in too much draught, this helps regulate temperature on warmer nights. The bag packs down into a compression sack with straps and includes a travel-friendly carry bag, which keeps it compact for backpacks and emergency kits. Colours vary so families can pick personal options.

Usage tips
It’s a good fit if you need a versatile, easy-to-clean sleeping bag that performs across seasons and stows small in a pack. For chillier nights add a liner for extra warmth, while on warm evenings open the bottom zipper to improve airflow. Bear in mind that extreme alpine conditions are outside the stated temperature range, so for severe cold choose specialist equipment.
Care & maintenance
Machine wash on a gentle cycle and tumble dry low where the care label permits, this helps preserve loft in the hollow fibre fill. Store uncompressed between trips to maintain insulation over time. The water-resistant outer helps fend off light drizzle but drying thoroughly before packing prevents damp odour.
