Sea to Summit Camp Plus SI Mat

With an R-value of 4.3, this pad is designed for four-season versatility. It provides enough insulation for most winter conditions, though if you are camping in extreme sub-zero temperatures, you might want to pair it with a closed-cell foam pad for extra thermal protection.

The open-cell foam inside expands when you open the valve, drawing air in automatically. Once it reaches its initial shape, you can add a few breaths to reach your preferred firmness or use the multi-function valve to make micro-adjustments.

Yes, it includes a repair kit. It is always a good idea to keep this kit in your pack, as even durable 75D polyester can occasionally snag on sharp rocks or thorns.

Absolutely. While it features a Pillow Lock system specifically designed to secure Sea to Summit pillows in place, you can use any pillow you like. If you are using a non-compatible pillow, it just won't lock into the surface fabric.

At nearly 2 to 3 pounds depending on the size, this pad is more focused on comfort and durability than ultralight performance. It is a great choice for base camping or shorter backpacking trips where a good night's sleep is a priority over shaving every possible ounce.

To pack it down, open the valve to the deflation setting and roll the pad tightly from the opposite end to push the air out. Once rolled, you can close the valve to prevent it from re-inflating while you slide it into the stuff sack.
