Self-Inflating Sleeping Pad - Cosmic

The pad contains open-cell foam that naturally expands when the valve is opened, drawing air inside to create loft. You simply unroll the pad, open the valve, and let it sit for a few minutes before topping it off with a breath or two if you prefer a firmer surface.

At just under an inch thick, this pad is designed primarily for portability and smoothing out uneven ground rather than providing plush, mattress-like cushioning. Side sleepers who need significant hip support may find it a bit thin, though it is excellent for back sleepers or those looking to shave weight.

When packed, the pad measures approximately 4.72 by 24.61 inches. It rolls up into a relatively slim cylinder that fits easily into most standard hiking backpacks, though you will want to ensure your pack has external straps or enough internal volume to accommodate the 24-inch width.

Yes, the exterior is constructed from durable, waterproof material specifically designed to withstand contact with the ground. While it is rugged enough for direct use, using a groundsheet or tent footprint is always recommended to protect the material from sharp debris like thorns or jagged rocks.

This pad is not rated for extreme cold or snow camping. Because it lacks a high R-value insulation rating, it is best suited for three-season use in spring, summer, and early autumn conditions.
