THERM-A-REST - Ohm 20F/-6C

We're sorry, this product is no longer available, please see below for details of any replacement.

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 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 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 Nikwax Hydrophobic Down: PFC-free and absorbs 90% less water and dries 3x faster than untreated down.
  • Responsible Down Standard Certified: 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.
