The BSWOLF SL010-1 Envelope Sleeping Bag is the reliable three-season companion that adapts to your conditions. Available in three fill weights — 1.35 kg, 1.5 kg (Widen), and 1.8 kg — it covers the full spring-to-autumn temperature range from 5°C to 15°C. The 190T anti-tear polyester shell is waterproof and durable, while the hollow cotton fill provides consistent, breathable insulation that holds up across seasons.
The splicing double zipper (L + R options) lets you connect two bags for a spacious double sleeping bag — ideal for couples. A built-in compression bag with two tightening straps reduces packed volume by half. The bottom zipper ventilation lets you regulate temperature when conditions warm up. Note: the Widen option (1.5 kg) is only available in the wider 230 × 90 cm cut.
