Down Sleeping Bag for Adults – Cold Weather Duck Down Mummy Bag | Traverseon

Warm Down Insulation with a Roomier Mummy Fit for Cold-Weather Camping

Traverseon uses 1500 g (3.31 lb) of water-washed white duck down with baffled construction to help distribute insulation from shoulders to feet. The sleeping bag measures approximately 215 × 78 × 55 cm (84.6 × 30.7 × 21.7 in), with a roomy 78 cm shoulder width that gives side sleepers and frequent turners more space than a tightly cut mummy bag. The product page currently lists a temperature range of approximately 0°C to -20°C (32°F to -4°F), with actual warmth depending on conditions, sleeping pad insulation, clothing, and individual cold tolerance. A two-way zipper also lets you vent part of the bag when nighttime temperatures rise instead of choosing between staying fully zipped or opening the entire bag.

The 320T DWR nylon shell helps manage morning dew, tent condensation, and everyday outdoor moisture, while the machine-washable construction makes routine care easier than many traditional down setups. At approximately 2.4 kg (5.29 lb) with a packed size of about 28 × 50 cm (11.0 × 19.7 in), this bag is better suited to car camping, vanlife, weekend trips, festivals, and guest use than ultralight long-distance backpacking. The heritage-inspired woven pattern adds a distinctive look beyond standard technical sleeping bags, with Red and Blue color options currently available.

Heritage-Inspired Woven Design, More Character at Camp
The woven exterior adds a distinctive heritage-inspired look to tents, vans, cabins, and guest spaces, giving the sleeping bag more personality than a standard solid-color technical bag.

1500 g White Duck Down, Thick Insulation for Colder Nights
Filled with 1500 g (3.31 lb) of water-washed white duck down, the baffled construction helps distribute insulation from shoulders to feet for consistent warmth during cold-weather camping and overnight stays.

Cold-Weather Design, Built for Lower-Temperature Trips
The product is currently listed for approximately 0°C to -20°C (32°F to -4°F) use, with actual warmth depending on sleeping pad insulation, clothing, humidity, wind exposure, and individual cold tolerance.

320T DWR Nylon, Better Protection from Dew and Tent Moisture
The 320T DWR nylon shell helps resist morning dew, condensation, and light outdoor moisture, while the machine-washable construction makes routine care more convenient.

78 cm Shoulder Width, More Room for Side Sleepers
A shoulder width of approximately 78 cm (30.7 in) gives side sleepers and frequent turners more room to change position than a tightly cut mummy bag while still maintaining a tapered cold-weather shape.

Two-Way Zipper, Vent Heat as the Night Warms Up
The dual-direction zipper lets you open part of the bag for extra ventilation when temperatures rise, giving you more control over airflow without fully unzipping the sleeping bag.
