Ultralight Down Camping Sleeping Bag by Therm-a-Rest

The Ohm 20F/-6C is a top choice for ultralight weight and packability without sacrificing warmth and comfort. Weighing just 1 lb. 6 oz (635g), this sleeping bag offers a roomy fit and the option to convert into a two-person quilt. Filled with high-loft 900-fill Nikwax Hydrophobic Down, it provides excellent warmth-to-weight performance with moisture-resistant insulation that dries quickly and compresses small. The box baffled construction ensures consistent warmth distribution, while heat-mapped Zoned Insulation prioritizes key warmth areas. The ultralight shell fabric and high-loft down keep the overall weight and packed size to a minimum.

Unique in its class, a full-length zipper extends completely around the footbox, allowing it to be opened flat as a quilt for added comfort and mobility on warm nights. Two fully unzipped Ohm sleeping bags can be stacked and zipped together to create a comfortable double bag for adventure duos.

Crafted with the Therm-a-Rest commitment to quality and performance, the Ohm keeps your pack featherweight and versatile without sacrificing performance.

100% Nylon Imported. RDS-certified and PFC-free 900 Fill Nikwax Hydrophobic Down insulation absorbs 90% less water and dries 3x faster than untreated down. The full-length zipper extends around the footbox, allowing for use as a quilt, custom ventilation, or mating with another Ohm sleeping bag. Box baffled construction uses mesh walls to maximize loft and minimize cold spots, while a drawcord at the collar seals in heat. Ultralight shell material, insulation, and precision design keep packed size to an absolute minimum. Combine two fully unzipped Ohm sleeping bags to create a cozy two-person sleeping bag. Responsible Down Standard Certified ensures the waterfowl in the down supply chain are treated humanely.
