The Big Agnes Iron Mountain Air Sleeping Pad will have you sawing logs in no time. At 2. 5 inches thick, this deluxe pad provides plenty of cushioning for all types of summer overnighters from backpacking trips to car camping. But plush comfort doesn't have to mean lots of bulk the Iron Mountain fits into an included stuff sack that's about the size of a Nalgene. Bonus: This pad comes with a repair kit, and if you have a Big Agnes sleeping bag, you can deflate the Iron Mountain while it's still in the bag's pad sleeve, and stuff it all into a compression sack.
