Cumulus neo Quilt 450

The Cumulus neo Quilt 450 sits among the colder options in the neo range — 450 g of 900 cuin goose down (96/4 ratio) in H-baffles gives a manufacturer comfort rating of -2 °C and a limit of -8 °C, reaching into autumn and winter territory. Total weight of 610 g tracks the larger fill, and packed size grows to 22×16 cm (4 l). The footbox has a trapezoidal shape, different from the anatomical footboxes on the lighter models in the series — a simpler but roomier approach. Shell and liner both use the same 19 g/m² Toray Airtastic fabric with a DWR finish, and elastic straps fit pads 50–60 cm wide. Like the rest of the neo line, it has no back panel or zip, so warmth depends on pairing it with an insulated pad. Available in blue, made in Poland. A weight-per-degree figure of 76.3 g/°C is among the better ratios in the catalog. Suited to late-autumn through mild-winter trips, where a quilt-plus-pad system still makes sense over a full sleeping bag.
