Therm-A-Rest Ohm 20F/-6C
When ultra-lightweight and compact pack size are essential, but you can’t compromise on warmth and comfort, the Ohm 20F/-6C is hard to beat. Weighing just 635 g, the Ohm sleeping bag brings balance to your backcountry adventures, offers a generous fit, and can be converted into a two-person blanket. Filled with high-loft 900-fill Nikwax Hydrophobic Down™, it delivers a first-class warmth-to-weight ratio with moisture-resistant insulation that dries quickly and compresses down small. The thermally efficient box-chamber construction ensures even heat distribution, while zoned insulation targets critical warmth zones. Ultra-lightweight shell material and high-loft down keep total weight and pack size to a minimum. Unique in its class: A full-length zipper runs all the way around the footbox, allowing it to open completely as a blanket for added comfort and freedom of movement on warm nights. Two fully opened Ohm sleeping bags can be layered on top of each other and zipped together to create a cozy double sleeping bag for adventure duos. Designed with Therm-a-Rest quality for performance, the Ohm keeps your gear ultralight and versatile without sacrificing performance.
