Cumulus Lite Line 300

Cumulus Lite Line 300 

The Cumulus Lite Line 300 is a midweight ultralight sleeping bag designed for 2–3 season use, making it ideal for spring–summer mountain trips, forest bivy overnights, and fast-and-light bikepacking adventures.

Made from lightweight Pertex® Quantum (29 g/m²), it delivers exceptional performance at just 600 g, filled with 300 g of high-quality Polish goose down. The advanced trapezoidal baffle construction maximizes thermal efficiency, providing reliable comfort in temperatures around 4°C, while still maintaining excellent packability.
The updated design features a shark-fin footbox that improves comfort and prevents down compression, keeping your feet warmer. A fully shaped ergonomic 3D hood with adjustable drawcords enhances insulation and fit, while the larger mesh internal pocket allows convenient storage of essentials like a smartphone or powerbank.
A full-length YKK® zipper with anti-snag protection ensures smooth operation and can be opened from the foot end for ventilation in warmer conditions. Thoughtful details like a noctilucent zipper pull make handling easy, even in low light.
Perfect for fast-and-light enthusiasts, the Lite Line 300 can also be extended into cooler conditions when combined with additional insulating layers.
