This liner is very light and soft. It keeps you from sticking to your sleeping bag and one of the best features is that after each sweaty trip you can wash this and your sleeping bag doesnt stink of every hike you have ever been on. Great!!
This sheet is comfortable. It is added weight to your pack but not much. I would recommend getting this sheet for your bag if you 1. get cold easily 2. don't like the feel of nylon against your skin 3. miss your comfy sheets at home while camping 4. don't want to get your sleeping bag dirty 5. like to sleep naked in your sleeping bag.
