Cumulus Lite Line 400
The Lite Line 400 is the warmest model in our ultralight 3-season range — built for mountain missions, bikepacking trips, and backcountry camps from spring to late autumn.
Weighing just 705 g, it delivers exceptional warmth thanks to 400 g of premium Polish goose down 850FP and ultralight Pertex® Quantum (29 g/m²) fabric that is soft, durable, and fully downproof.
Anatomical details make a real difference in the field: a shark-fin footbox for natural comfort, a fully shaped 3D hood for efficient heat retention, and a smooth full-length YKK® zipper with anti-snag protection and two-way ventilation.
Lightweight, reliable, and impressively warm for its weight, the Lite Line 400 offers outstanding warmth-to-weight performance, ideal for demanding adventures and for those who tend to feel cold even in summer.
