Bulky but extremely comfortable.

Rolled up these are much larger than sleeping pads or small air mattresses. Like most ALPS products, not for backpacking due to the weight and size. They assume and release air through an adjustable hard-plastic valve in one corner that seems a little brittle and I could see it cracking at some point. Thick material, would take a bit of abuse to break a seam or puncture. ALPS sacrifices weight for durability and comfort.
