Therm-a-Rest has been known as makers of fine sleeping pads. They recently entered the sleeping BAG market. Had the chance to review the Altair zero degree bag.
This bag comes with stretch straps built in to the underside of the bag. These straps are designed to hold your Therm-a-Rest pad in place while you sleep. I was impressed with the bag and the simplicity of the strap design and function. See my video review for full details on this bag.
- Holds pad in place
- Zipper can snag easily
Where to Buy
