The AEGIS D Series sleeping bags are engineered for outdoor enthusiasts who demand comfort, performance, and portability. Designed with a slightly wider cut in the torso and hips, this sleeping bag accommodates a range of body types and sleeping positions without compromising thermal efficiency. Whether you’re lying on your side or shifting during the night, the relaxed mummy silhouette ensures you stay warm and comfortable throughout the night.

Constructed with a high-performance iFlex®15D DWR Nylon outer fabric, the bag offers excellent resistance to water and wear, making it suitable for use in damp or variable weather conditions. The interior lining uses the same high-quality iFlex®15D Touch soft Nylon, which feels gentle against the skin and reduces friction—ideal for sensitive users or extended use. This dual-layer fabric system contributes to the bag’s durability and comfort while keeping weight low.

At the heart of the bag’s performance is 650 Fill Power white duck down. This premium insulation material offers superior warmth-to-weight efficiency, allowing the bag to stay lightweight while providing reliable thermal protection. The fill weight of 380g (D1-regular) and 400g (D1-long) ensures sufficient insulation for temperatures down to 5°C (41°F) in comfort mode, with a limited rating of -10°C (14°F) for extreme conditions. This makes the D Series suitable for indoor use, summer camping, and spring and autumn treks across the UK’s varied terrain.

A key feature is the anti-snag zipper track system. Unlike standard zippers that can tear fabric or catch on threads, this reinforced design ensures smooth operation and long-term reliability—especially important when adjusting ventilation or accessing the bag at night. The draft baffle, located along the zipper and collar, acts as a thermal barrier, preventing cold air from entering and helping maintain a stable internal temperature.

Available in two sizes—D1-regular (fits up to 178cm) and D1-long (fits up to 190cm)—the bag caters to a wide range of users. Both models pack down to a compact 15x28cm, making them easy to stow in a backpack or rucksack. The included compression sack allows for efficient packing, while the breathable mesh storage bag helps keep the down dry and prevents damage during long-term storage.
