Therm-a-Rest Ohm 20F/-6C sleeping bag 2024

When you need ultralight weight and packability, but can’t go without warmth and comfort, the Ohm 20F/-6C 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 keeps overall weight and packed size to an absolute 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 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.
