The Hyalite Equipment Classic SI self-inflating sleeping pad balances comfort and weight. Available in multiple sizes, the Classic SI pad is an affordably-price option for three-season camping and backpacking.
An expandable foam core provides the self-inflating Classic SI with an R-value of 4.0 (NOTE: with a thicker base, the Wide size of the Classic SI has an increased R-value of 5.0) and makes the pad easy to use. Simply unroll the pad and open the valve. Open-celled foam responds by soaking up air, similar to the way in which a sponge absorbs liquid. Once the Classic SI has had time to inflate, you can adjust firmness by manually adding or releasing air before re-tightening the valve.
The Hyalite Equipment Classic SI sleeping pad is available in Two-Thirds (20" x 48" x 1.0"), Regular (20" x 72" x 1.0") and Wide (25" x 78" x 2.0") size offerings. Each Classic SI self-inflating sleeping pad includes a stuff sack, a wrap strap and a field repair kit.
