The Thermarest Ohm 20F/-6C UL is a lightweight, versatile down sleeping bag with a roomy, semi-rectangular shape for individual use or can opened up and used as a double quilt. Ideal for fast and light solo adventures in colder temperatures or for couples and group camping.
The Ohm 20F/-6C is difficult to beat when you need ultralight weight and packability but can't sacrifice warmth and comfort. The Ohm sleeping bag, which weighs only 635g (standard length), balances out wild camping activities with a roomy fit and the flexibility to become a two-person quilt. It provides excellent warmth-to-weight performance with moisture-resistant insulation that dries quickly and compresses small, filled with high-loft 900-fill Nikwax Hydrophobic DownTMTM. Heat-mapped Zoned Insulation gives priority to important warmth areas while thermally efficient box baffled construction maintains consistent warmth distribution. High-loft down and an ultralight shell fabric keeps the overall weight and packed size to an absolute minimum.
Unusual for its class, the footbox has a full-length zipper that wraps completely around it and can be opened flat like a quilt for extra comfort and mobility on warm nights. For comfortable double bags for adventure teams, you can stack and zip together two Ohms that are completely unzipped. The Ohm keeps your pack light and adaptable without compromising on performance because it was designed with Therm-a-Rest's commitment to quality and performance.
