Great bag, keeps you super warm

  • Familiarity: I've put it through the wringer

Love this bag, it packs down really small and is super lightweight. I have the 0 degree version and slept in a hammock in 20 degree weather one night and slept like a baby. Totally worth the price. I've accidentally spilled water on it to and I was still warm and dry. If you're looking for a great back packing pack to keep you warm, this thing is what you want.
