Sea to Summit Camp Plus Sleeping Mat

With an R-value of 5.3, this mat is well-insulated enough for three-season use and can handle chilly shoulder-season nights. While it offers excellent warmth, it is primarily designed for camping, hunting, and paddling rather than extreme alpine winter expeditions.

The mat uses open-cell foam that expands when you open the high-flow valve, drawing air in automatically. You can simply top it off with a few breaths if you prefer a firmer sleeping surface.

The contour shape is actually designed to give you more usable surface area where you need it most, such as at the shoulders and hips. It accommodates natural sleeping positions better than a standard rectangular mat without adding unnecessary bulk.

Yes, the 75D recycled polyester is quite robust and resistant to abrasions. While you should always clear your campsite of sharp rocks or sticks before laying it down, the material is built to withstand the wear and tear of regular outdoor use.

When packed, it measures 11 inches long by 6 inches in diameter. It includes a side-loading stuff sack, which makes it significantly easier to roll up and stow away compared to traditional top-loading bags.

The foam cutouts are strategically placed to reduce weight while maintaining insulation in critical areas. Because the mat has an extra-thick profile, you still get plenty of cushioning and depth, so you won't feel the ground beneath you.
