Experience unmatched warmth without the weight. This innovative liner blends 30% silk with 70% Thermolite® technology, creating a ripstop fabric that outperforms traditional insulators. The hollow-core fibres work overtime to trap air and maintain heat, while moisture-wicking properties pull dampness away from your skin for rapid evaporation. Dries 20% faster than standard insulating fabrics and 50% quicker than cotton—perfect for adventurers who refuse to compromise on comfort or pack weight. Lightweight, durable, and engineered for performance in any condition. Features: • Size: 241 x 90/56cm • Weight: 160g • Packing Size: 15 x 8cm • Added Temperature: up to +6.3° C Please Note: We are unable to accept returns of sleeping bag lines where the seal has been broken. All details are in the listing, so please do NOT buy this if you are unsure of suitability.
