Comfort Light SI Sleeping Pad

With an R-value of 3.1, this pad is designed for three-season use. It provides adequate insulation for spring, summer, and autumn, but you will likely need a higher R-value pad for freezing winter temperatures.

The pad uses open-cell foam that expands when the valve is opened, drawing air inside automatically. While it does most of the work, you may need to add a few breaths of air to reach your preferred firmness.

The surface features an anti-slip silicone print designed to keep your sleeping bag in place. This helps prevent the common issue of sliding off your mat on uneven ground.

PillowLock is a series of hook-and-loop patches that secure a compatible Sea to Summit pillow to the top of the pad. While it works best with Sea to Summit pillows, you can use any pillow, though it won't lock into place without the proprietary system.

Yes, the 2-inch thickness combined with the supportive foam core provides a solid foundation. However, if you are a side sleeper who prefers a plush, mattress-like feel, you might find it firmer than air-only pads.

It packs down to 11 inches by 5.5 inches. While it is bulkier than ultralight air pads due to the self-inflating foam, it remains manageable for most backpacking setups.
