Sea to Summit UltraLight Mat

Sea to Summit's UltraLight Mat has been on the market for a few years, and it's still a top choice for minimalist backpackers.

Pros: 

The UltraLight Mat weighs in at under 14 ounces and packs down smaller than the size of a soda can. If you're an ultralight backpacker, the appeal is obvious. The Air Sprung Cell design offers unexpected support, and the one-way valve is intuitive and effective. One tester reported zero issues packing this lightweight sleeping pad back down to its original size.

Cons: 

Don't expect this pad to keep you warm. With an R-Value of 1, this pad is best used on summer nights.

Bottom Line: 

One of the lightest and most compact sleeping pads you're going to find on the market at this low price point.
