Warm and Light
- Gender: Male
- Familiarity: I've used it several times
This liner packs down really small which is great. I bought it both to keep my bag clean and add warmth on some colder nights. This will do both things quite well. It adds at least 10 degrees of warmth. I used this with a 15 degree bag at city of rocks in low 30 degree weather, sleeping open air and was almost two warm. It is a little narrow but still comfortable.
