Big Agnes Sleeping Bag Lost Ranger 3N1 15 (650 RDS DownTek) Mercury -3°C/-9°C

• Two integrated down sleeping bags with Big Agnes Padlok™ Sleep System

The Lost Ranger 3N1 sleeping bag combines two sleeping bags for three different configurations - providing a sleep solution that's just right at a wide range of temperatures.

This modular bag design offers just what you’d expect: three bag configurations in one simple, yet technical sleep system that stays attached to your pad, so you won’t roll off in the middle of the night. Use just outer bag for warm summer nights, just the inner bag when temperatures start to drop, and on the coldest trips combine both for ultimate warmth - it's the only bag you need for 3-season camping, backpacking and everywhere in between. These lightweight, down-fill bags deliver comfort and versatility no matter your sleep style or temperature preference.
