What Our Gearhead(R) Experts Are Saying:"I started using the UL Recovery Sleeping Bag Liner on multi-day trips, and it really changed how rested I feel after a night out. It's light, compact, and the Celliant fabric actually makes a noticeable difference in warmth and recovery. Bonus-it keeps my bag cleaner for longer too."When we're pushing hard on trail and rest is our greatest asset, we want every advantage we can get.
