Cumulus Neo Quilt 300

Cumulus Neo Quilt 300

The Cumulus Neo Quilt 300 is an ultralight three-season down quilt with closed footbox designed for hikers, bikepackers, and fastpackers who want to minimize pack weight without sacrificing warmth or sleeping comfort. By removing unnecessary insulation underneath the body and relying on a sleeping pad for ground insulation, the quilt concentrates all of its loft where it performs best — above and around the sleeper — delivering excellent thermal efficiency with a remarkably low total weight of just 455 g.
Filled with 300 g of premium ethically sourced Polish goose down with outstanding 900 FP loft, the Neo Quilt 300 offers impressive warmth for temperatures around freezing while remaining highly compressible for compact packing. Its advanced H-chamber construction ensures even down distribution and reduces the risk of cold spots, helping maintain consistent warmth throughout the night.
The ergonomic shark-fin-shaped closed footbox provides extra space and comfort for your feet while efficiently retaining heat. Around the neck, an elastic drawcord combined with an insulated down collar helps seal in warmth during colder nights. The included attachment system with elastic straps and flat buckles securely connects the quilt to sleeping pads 50–60 cm wide, helping prevent drafts while still allowing natural freedom of movement.

The quilt measures 83 cm wide at the shoulders and 52 cm at the footbox. The standard size is suitable for users up to 185 cm tall.

Compared to a traditional mummy sleeping bag, the Neo Quilt 300 offers a far less restrictive sleeping experience. Whether you sleep on your side, back, or frequently change positions during the night, the quilt adapts naturally to your movements for greater comfort on trail.
Built from ultralight Toray Airtastic™ 7D ripstop fabric with DWR treatment, the Neo Quilt 300 balances minimal weight with long-term durability for demanding outdoor use. Developed and field-tested by Cumulus®, it is an ideal choice for users seeking a highly packable and thermally efficient sleep system for spring, summer, and early autumn adventures.
