The Rab Ascent 900 is a great bag for those looking to camp in colder weather but don't want to pay the high price for a lighter bag. Our testers found it to be warmer than its closest competitors, the Big Agnes Storm King 0 and the Kelty Cosmic Down 0. A wide cut makes it comfortable for back and side sleepers. While not the lightest bag, the highly weather resistant shell, lofty 650 fill power duck down, and excellent features earn it our Best Bang For Your Buck Award. For a cool $360, you can jam out into the hills for some fun without freezing at night when the temps are dipping into the low teens.
The Ascent 600 has seen some minor updates. See the latest incarnation of the bag in the photo above and read on to see what's changed.
