Down Sleeping Bag X-Lite 400 | -1°C ♀ | -7°C ♂ Cumulus

The Cumulus X-Lite 400 sleeping bag is the perfect choice for high-paced adventures, whether it’s trail running, ultralight hiking, bike touring, or mountaineering. If your goal is ultralight gear that packs easily, this sleeping bag is just for you.

Minimalist Design – High-Quality Materials

The X-Lite 400 is designed with a minimalist approach, focusing on lightness and functionality. This sleeping bag is made from the world’s lightest down-proof material, only 19 grams per square meter Toray Airtastic® fabric, and features a 2/3-length 3 mm YKK® zipper. The precisely shaped design ensures optimal down insulation while keeping the weight to a minimum. Anatomically shaped footbox and three-dimensional hood provide a snug and warm fit. The filling is ethically sourced, high-quality 900 FP Polish goose down, offering maximum warmth.

Trapezoid Baffle Construction

The X-Lite series sleeping bag features advanced trapezoid baffles that reduce heat loss between the baffles. Two adjacent baffles form a trapezoid, meaning individual baffles always connect at a slight angle.

Sleeping Bag Design – Mummy Shape

The X-Lite 400 has a mummy shape, not extremely tight, which improves thermal insulation. The footbox is anatomically shaped, meaning it has a slightly slanted design (see pictures). The 3D-shaped adjustable hood ensures a good fit. This sleeping bag is not suitable for those who need space to move around.

3D Hood and Wind Protection

The hood of the sleeping bag is 3D-shaped and adjustable in two places – the different textures of the drawstrings make it easier to adjust in the dark. The zipper is protected by a down-filled strip to prevent heat loss and protect against wind.
