Quick overview

The Thermarest Ohm 32F/0C brings balance to ultralight adventures with a roomy fit and the ability to convert into a two-person quilt. The sleeping bag uses a thermally-efficient box baffled construction to ensure warmth and comfort in an ultralight package.

Designed with high-quality materials and Therm-a-Rest performance features, the Ohm keeps your pack featherweight and versatile without sacrificing an ounce of performance. Storage sack and compression stuff sack included.


Down insulation has an excellent insulation-to-weight ratio. It is very compressible, so a bulky, warm sleeping bag, can still be reduced to a small, manageable package. Also, the weight of a down-filled sleeping bag is much lower than that of a synthetic-filled sleeping bag with a similar temperature range. The temperature range of down is greater than synthetic materials such as polyester. This means that a warm sleeping bag can be used comfortably even at higher temperatures. Finally, down has a much longer lifespan.


  • Ultralight: The lightest piece in its class, the Ohm sets a new standard for high-performance outdoor equipment
  • 900-fill Nikwax Hydrophobic Down™: Stays drier and maintains loft 60 times longer than untreated down
  • Unrivaled Packability: Lightweight materials and precise design allow for a smaller packed size than ever before
  • Box Baffled Construction: Uses mesh walls to maximize loft and minimize cold spots
  • Roomy Fit: Semi-rectangular shape allows for a spacious and warm night at camp
  • Versatile: Open the bag to convert it into a quilt for milder weather. Zip two Ohm's together to make an ultralight sleep system for two
  • Responsible Down Standard Certified: Certification that ensures that the waterfowl in the down supply chain are treated humanely
