Big Agnes Blue Lake 25 Mummy Bag

Loved this sleeping bag! As someone who is constantly cold, this thing kept me nice and toasty on our 10 camping trip. I actually looked forward to sleep on the ground snuggled up in this each night of our trip. Very high quality at a great price point. Only complaint is that it was a little big and touch to compress in a backpack, but would gladly take the extra space to be warm.
