When you need ultralight weight and packability, but can’t go without warmth and comfort, the Ohm 20F/-7C is hard to beat.

Weighing in at just 1 lb. 6 oz (635g), the Ohm sleeping bag brings balance to backcountry pursuits with a roomy fit and the ability to convert into a two-person quilt. Filled with high-loft 900-fill Nikwax Hydrophobic Down™™, it delivers top-notch warmth-to-weight performance with moisture-resistant insulation that dries fast and compresses small.

Thermally efficient box baffled construction maintains consistent warmth distribution while heat-mapped Zoned Insulation prioritizes key warmth areas. Ultralight shell fabric and high-loft down keep overall weight and packed size to an absolute minimum. Unique in its class, a full-length zipper extends completely around the foot box, allowing it to be opened flat as a quilt for added comfort and mobility on warm nights.

Two fully unzipped Ohms can be stacked and zipped together to create a comfy double bag for adventure duos. Designed with the Therm-a-Rest commitment to quality and performance, the Ohm keeps your pack featherweight and versatile without sacrificing an ounce of performance.
