Bueno, but a bit bulky
This really is an excellent pad to take with you on most camping/backpacking trips; it's very lightweight, pretty durable, and insulates you and your bag well. The only downside is the bulkiness of it when it's rolled up. Total, mine is about 8 inches thick when rolled. Think of strapping an extremely light log somewhere on your pack.
Other than the thickness, this thing is great, and the value can't be beat.
