Add an ALPS Mountaineering dual foam mat to the bottom of your sleeping bag to improve the level of comfort. The dual foam mats are made with egg crate foam on the top and dense XPE foam on the bottom to make a great combination for warmth and comfort. The dual foam mats are still lightweight enough that you won't be hauling around too much weight on your next camping trip. Each foam mat comes with straps so when you're finished, you can roll it up and easily transport and store it.
