Lost Ranger 3N1 0°
two integrated down sleeping bags with Big Agnes Padlok™ Sleep System
Description

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.

Cleaning
Machine Wash
Machine wash in a washing machine WITHOUT AN AGITATOR, agitators are likely to cause damage to your gear. Oversized bags require oversized machines, you may need to go to a laundromat to wash your larger bags. Wash on a warm, gentle cycle. Use gear specific soap, we recommend Nikwax Down Wash Direct. Rinse twice.
Drying
Tumble dry low heat with clean tennis balls. Finish by drying on high heat in 5 minute intervals to loft down. *Allow to cool between intervals to avoid damage to shell*
Warnings
Do not use fabric softeners. Do not bleach. Do not iron. Do not dry clean.
