An ergonomically-shaped and well-balanced trekking mummy bag, with great technical features.

The Lupus -3 from Haglofs is a well-balanced and affordable trekking mummy-style sleeping bag that uses their lightweight Tri-Fusion® insulation to provide a comfortable night’s sleep down to temperatures as low as -3C. 

Tri-Fusion® is a lightweight polyester-fibre insulation that uses a mix of three different kinds of fine denier hollow fibre to provide bags of warmth without the bulk. The mix of fibres is fused together into an insulating and durable 3D-web by a process called melt bonding. The resulting insulation construction is very warm despite its a low weight, and because it’s synthetic, it’ll continue to keep you warm, even when wet.

The bag comes in an ergonomic mummy shape that saves weight while maintaining warmth by hugging the body in all the right places. There’s an anti-snag ¾ length zipper with draft excluder, an internal pocket for your essentials and one for your pillow.

If you’re looking for a new sleeping bag from a hugely respected brand that uses easy-to-care-for synthetic insulation and is good down to -3, the Haglofs Lupus -3 is a solid choice.
