The Therm-a-Rest Altair HD Sleeping Bag is a winter down sleeping bag for settling into camp after snowshoeing the day away. Stuffed full of 750+ Hydrophobic Down insulation, it's more resilient to moisture (than untreated down) and the ThermaCapture™ lining increases warmth without adding much to the weight of the bag. The 2lbs, 7oz (regular length) bag has a EN Comfort rating of 23°F with a draft collar and tube that prevents cold air from sneaking into your bag late at night. The two SynergyLink™ Connectors allow you to strap the bag to your mattress, roll prevention at it's best. I just made 'roll prevention' up, but it's totally a thing, because rolling off your mattress mid-sleep is terrible.

FEATURES of the Therm-a-Rest Altair HD Sleeping Bag

  • Zoned Insulation design features box-baffled 750+ fill Nixwax Hydrophobic Down with sewn-through insulated bottom
  • Reflective ThermaCapture™ lining for added warmth without excess weight or bulk
  • SynergyLink Connectors integrate your Therm-a-Rest mattress for better comfort and efficiency
  • Heat trapping draft collar and full-length zipper draft tube
  • Differential cut maximizes loft
  • Snag-free zipper. So no snags.
  • Cinchable hood helps lock in warmth
  • External zip pocket for stowing super important stuff
  • Stuffsack and storage sack are totally included
  • FYI - Altair is the twelfth brightest star in the night sky, and is used in celestial navigation. Space is pretty cool, am I right guys?

Rated 4 out of 5 by from Great Bag This bag is absolutely genius. The straps on the underside do a great job of keeping the mattress underneath you as you sleep. No more waking up on the ground next to it haha. It even keeps the mattress in place in a hammock! No easy feat! That was the primary reason I bought this bag. Of course, this lends to it's other strength, it can get by with very little insulation on the back side, because your pad will always be there. This allows for a much lighter weight bag. Less than 2.5lbs for a 0deg bag is extremely impressive. Unfortunately having less insulation is a draw back in warmer weather in a hammock. When temps are above 50deg, using a pad would normally be unnecessary, but with this bag the backside is too thin. I also think the bag is cut too wide. In cold weather this is definitely noticeable with cold spots developing within the bag. Overall it is an amazing bag, but maybe a little steep on the price.

Rated 4 out of 5 by from super warm I like the bag, it stays warm to mountain temps, but takes very long to dry when wet

Rated 4 out of 5 by from the altair bag seemsto be as much bag as i can expect to need for cold weather camping. It seems to seal quite well and feel as good as it keeps warm.
