You can take advantage of the superb insulating power of down without concern about down's one disadvantage – its loss of loft when wet – with the Altos 20°F Ultralight Down Sleeping Bag from Teton Sports. The Altos' hydrophobic MTN-DRY down fill retains its loft and will keep you warm even in wet conditions.
The left-side-zip, mummy-style Altos features a three-piece hood that can be adjusted closely around the face and a draft tube along the full-length zipper to prevent heat from leaking out during the night. The shell is made of light but strong 20-denier rip-stop fabric, and the lining is a soft 20-denier nylon for comfort.
Measuring 84" long, 32" wide at the shoulder and 17" wide at the foot, the Altos weighs 2.5 pounds and packs down to 14 x 8 x 8" in its stuff sack.
