The Aegismax AIR is a high-performance, lightweight sleeping bag engineered for backpackers and hikers who demand efficiency, comfort, and packability. Designed for 3-season use, it excels in the UK’s variable spring, summer, and early autumn conditions—offering reliable warmth without excess weight.
Its mummy shape minimises dead air space, retaining body heat more effectively than rectangular bags. The snug hood and tapered foot box reduce heat loss through the head and feet—key areas for warmth retention. The 800 Fill Power ultra-dry goose down (95% white goose down, 5% feather) delivers excellent insulation with minimal weight.
The outer shell uses iFlex 10D nylon with a DWR finish—ultra-light, durable, and water-resistant. Inside, the soft-touch iFlex 10D lining is breathable and gentle on the skin, enhancing comfort during long nights.
Sewn-through baffles keep the down evenly distributed, reducing cold spots and maintaining consistent insulation. The YKK spliceable zippers allow the Regular and Long models to connect, enabling couples to share warmth or create a larger sleeping system when needed.
Packed down to just 20 x 12 cm (Regular) or 21 x 12 cm (Long), it’s ideal for long-distance trails, alpine hikes, and travel, where space and weight matter. The included compression sack and mesh storage bag ensure easy transport and proper, breathable storage when not in use.
