Alton Insulated Sleeping Mat (R4) Set

The Alton Insulated Sleeping Mat (R4) Set brings together four essential pieces of camping gear to create a complete lightweight sleep system. Combining the Insulated Sleeping Mat (R4), Sleeping Mat Fitted Sheet, Ultralight Pump Bag, and Ultralight Pillow, this bundle is designed to maximise comfort, warmth, and convenience while offering excellent value.

The Insulated Sleeping Mat provides an ASTM-tested R-Value of 4 for reliable year-round insulation, while the fitted sheet adds a soft, moisture-wicking sleeping surface and protects the mat from dirt and wear. An integrated pillow pocket keeps the included Ultralight Pillow securely in place throughout the night for improved sleeping comfort.

The included Ultralight Pump Bag makes inflating your sleeping mat quick and efficient without introducing moisture from breath, while also doubling as a lightweight dry bag for gear storage. Available in Regular, Regular Wide, and Large sizes, the complete set packs down compactly and is ideal for hiking, backpacking, camping, and military field use.
