Neo Quilt 600 is an ultralight, winter-capable quilt for experienced users, built for high thermal efficiency with more freedom to move when sleeping outside. Instead of insulation underneath, it relies on your sleeping mat as the primary barrier against ground chill, so all the down loft works where you need it most: from above and the sides. The result is lower weight with functional warmth even below 14 °F and a smart fit in a deliberately lightweight camp system.

A closed, spacious, shark-fin-shaped footbox keeps your feet comfortable all night. To boost performance, the Neo Quilt 600 uses H-shaped chambers filled with 21.2 oz of ethically sourced Polish goose down with exceptional 900 FP loft, pairing top quality loft with dependable heat retention. Ultralight Toray® Airtastic fabric helps keep weight low without compromising durability. A simple mattress attachment system compatible with pads 19.7 to 23.6 in wide helps seal out warm air loss as you change position, and the elastic neck drawcord, backed by a dedicated down-filled collar, lets you snug the top quickly when temperatures dip. In such demanding conditions, a high-quality, warm sleeping pad is essential and thorough head protection for the sleeper is required. Compared to a classic sleeping bag, a quilt gives you more space so you can sleep on your side, on your back, with knees tucked or simply in the position you like best.

At Cumulus® we have designed and field tested quilts for years, which is why the neo Quilt series is dialed in down to the details and ready for intensive outdoor use. It is made for users who value low pack weight and high thermal efficiency, without giving up versatility and comfort.
