The Cumulus sleeping mat delivers a "good night's sleep" when camping in a tent, bivvy, or under the stars in the great outdoors. Harnessing the power of Thermolite® polyester insulation with an impressive R5 rating, the Cumulus LT ensures optimal temperature regulation by facilitating warm air convection. Essentially, it provides a barrier or warmth of comfort between you and the cold ground. Crafted from ultra-durable 40D ripstop nylon, this mat strikes the right balance between toughness and lightweight design, weighing in at a mere 660g (730g with the pack/pump). It's a heavyweight performer in a lightweight package. When it's time to pack up and hit the trail, the Cumulus LT conveniently compresses to an ultra-compact size, effortlessly fitting into your pack without adding unnecessary bulk. And inflating the sleeping mat is a breeze thanks to the innovative pump sack. The Cumulus LT also has a built-in pillow, providing extra indulgence during rugged outdoor adventures.

There is a negligible difference in weight between the options with and without a pillow.
