Summary

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.

Pros

  • Lightweight
  • Warm
  • Holds pad in place

Cons

  • Zipper can snag easily

Where to Buy

Manufacturer's Description

A four-season, extremely lightweight, highly compressible 750+ fillpower goose down bag that’s warm enough to perform in the mountains all year.

  • Patent-pending SynergyLink Mattress Connectors—compatible with up to 25-inch-wide sleeping pads—create the most secure mattress connection in the industry. 
  • Thermal-mapped zonal insulation puts loft where it’s needed most. Insulation is concentrated in the top of the sleeping bag, where it traps rising warm air. 
  • Efficient Comfort design features extra room in the torso to allow shoulders, elbows and hips to move freely. At the head and foot the fit is closer, increasing warmth and decreasing overall weight.
  • A draft tube and collar are added for maximum heat retention. The sculpted hood and a trapezodial foot box are shaped to fit the body’s natural resting position. The bag also comes with snag-free zippers as well as a compartmental storage sack, lightweight stuff sack, and stash pocket.
  • Stuff sack: 20 x 46 cm | 8 x 8 in
  • Shell: 30D Nylon Rip stop with DWR
  • Lining: 30D Nylon
