LiteFoam™ Lite Foam 作为一种在 Therm-a-Rest 历史上具有突破意义的睡垫填充材料，其最大特点是较好地解决了如何使睡垫在质密的同时保持较轻重量的问题。得益于 Lite Foam 的特殊结构，使用这种材料的睡垫能够在保证使用性能的前提下，使用更少的填充材料，从而具有更轻的重量和更小的体积。
Staytek® Staytek is a custom-woven non-slip polyester fabric. In collaboration with our fabric mill, we discovered that bundling fibers and weaving them out of plane creates a highly texturized surface. This greatly increases the friction between your Therm-a-Rest and a slippery sleeping bag so you stay put on your mattress all night long
