Product description

Ultralight sleeping bag with an RDS down

The Ohm 20F/-6C down sleeping bag from Therm-a-Rest ensures a good night’s sleep in temperatures down to 0°C. It’s equipped with a high-performance goose down with a fill power of 900 cuin. The RDS-certified fill is not only ultra-light, but also hydrophobic thanks to a special Nikwax treatment, so moisture will be kept at bay.

Lightweight down sleeping bag for touring and trekking

The Ohm 20F/-6C down sleeping bag from Therm-a-Rest has a great warmth-to-weight ratio. It features a 10D ripstop nylon outer and lining that are extremely light. Plus, the outer surface has a water and dirt-repellent DWR treatment.

In addition, it was designed to be a mixture between a blanket and a mummy sleeping bag. It doesn’t have a hood and can be combined with a second sleeping bag to make it a cosy double sleeping bag for two people. You can even use it as a warm down duvet. The 640 g down sleeping bag can be compressed down to a size smaller than a football, so you can transport it with ease.

  • Ultralight down sleeping bag for trekking, touring and camping
  • RDS goose down with a fill power of 900 cuin
  • Good moisture protection thanks to the Nikwax and DWR coating
