4-Season Cotton Sleeping Bag – Lightweight Winter Envelope Mummy Bag for Backpacking & Camping

Four seasons, one bag. The 4-Season Cotton Sleeping Bag is engineered for adventurers who camp year-round and need reliable warmth when temperatures drop. Rated from 0°C to -10°C, this winter-ready bag combines a soft cotton fill with a durable terylene envelope shell to deliver consistent insulation across spring, autumn, and winter conditions.

The mummy-influenced envelope design balances the snug heat retention of a mummy bag with the roomier feel of an envelope style — giving you warmth without feeling confined. At a lengthened fit suitable for adults up to 2 m tall, it’s a bag that accommodates without compromise. The splicing zipper lets you connect two bags for a double configuration when the night calls for it.

Specifications

Why Choose This 4-Season Sleeping Bag?

• True 4-Season Versatility: Rated to -10°C but comfortable across all seasons — one bag that earns its place in your kit year-round.
• Cotton Fill for Breathable Warmth: Natural cotton insulation provides soft, breathable warmth that regulates temperature better than many synthetics in moderate cold.
• Durable Terylene Shell: Resistant to wear and tear, the terylene outer layer holds up across multiple seasons of hard outdoor use.
• Envelope-Mummy Hybrid Design: More room to move than a pure mummy bag, with better heat retention than a standard envelope — the best of both styles.
• Splicing Compatible: Join two bags for a double sleeping bag — ideal for couples or extra warmth on the coldest nights.
