DescriptionDown topquilt Neo Quilt 600 CumulusNeo 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 −10 °C and a smart fit in a deliberately lightweight camp system.A closed, spacious, anatomically shaped “shark-fin” footbox keeps your feet comfortable all night and helps eliminate empty air gaps in one of the zones most sensitive to cold. To boost performance, the Neo Quilt 600 uses a thoughtfully engineered H-shaped chamber design to deliver maximum insulation at low weight by eliminating cold spots. The quilt is filled with 600 g of ethically sourced Polish goose down with exceptional 900 Fill Power loft, pairing top quality loft with dependable heat retention. The shell and liner use Toray® Airtastic 19 g/m² fabric (7-denier ripstop, DWR finish, 100% nylon) to keep weight low without compromising durability.A simple mattress attachment system compatible with pads 50 to 60 cm wide helps seal out warm air loss as you change position. Two elastic straps with buckles let you quickly and securely attach neo Quilt to your sleeping pad, effectively preventing cold air drafts. The buckles can be brought closer together for a tighter seal, or spaced apart to create more room inside neo Quilt. Along the upper edge, an elastic drawcord combined with an additional down-insulated collar helps you seal the construction to minimize heat loss when temperatures dip. A neck snap closure lets you fasten the quilt around your neck so it doesn’t slip while you rest.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.Cumulus® 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.Key featuresVersatile design: Adaptable for various conditions, letting you fine-tune warmth and ventilation by adjusting how it wraps around you.H chamber construction: Thoughtfully engineered “H” chambers deliver maximum insulation at low weight by eliminating cold spots.Elastic straps: Two elastic straps with buckles let you quickly and securely attach neo Quilt to your sleeping pad, effectively preventing cold air drafts.Anatomically shaped footbox: An anatomical “shark-fin” footbox with an advanced insulation layout supports the natural position of the feet and eliminates empty air gaps.Minimalist adjustable collar: An elastic drawcord with an additional down chamber helps seal the construction, minimizing heat loss.Neck snap closure: A convenient snap lets you fasten the quilt around your neck so it doesn’t slip while you rest.Adjustability: Buckles can be moved closer together for a tighter seal, or spaced apart to create more room inside neo Quilt.Materials & constructionFill: 900 Fill Power ethically sourced Polish goose downShell and liner: Toray® Airtastic 19 g/m², 7-denier ripstop, DWR finish (100% nylon)Shape: Open mummy shapeNeck: Elastic band around the neck insulated with additional down tube snap for secure adjustment around the neckConstruction: H-shaped chamber designFootbox: Closed footbox constructionPad attachment system: Mattress attachment system based on elastic bands and flat buckles (pads 50–60 cm wide)Design: Minimalist and lightweight components and designFill distribution: Separately filled front and bottomIncluded: Stuffsack and storage sack includedTechnical specificationsDown quality: 900 FPTotal weight: 770 gDown weight: 600 gWeight of unfilled product: 170 gComfort temperature: -8 °CLimit temperature: -15 °CMaximum user height: 185 cmLength: 187 cmNumber of down chambers: 39Width (top/bottom): 83 / 52 cmStuffsack dimensions (height/diameter): 26 / 18 cmStuffsack volume: 6 L
