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 , 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 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.
  • 900-Fill : PFC-free and absorbs 90% less water and dries 3x faster than untreated down.
  • : Certification that ensures the waterfowl in the down supply chain are treated humanely.
  • Unrivaled Packability: Ultralight shell material, insulation and precision design keep packed size to an absolute minimum.
  • Roomy Fit: Semi-rectangular shape cuts weight while allowing for unencumbered sleep.
  • Multiple Use Modes: Full-length zipper extends around the footbox; allows for use as a quilt, custom ventilation or mating with another Ohm sleeping bag.
  • Pairable: Stack two fully unzipped Ohms and pair them for a cozy two-person sleeping bag.
  • Refined Warmth: Box baffled construction uses mesh walls to maximize loft and minimize cold spots, while a drawcord at the collar seals in heat.
  • Compression and storage sack included.
