ROCK FRONT Ultraliner is a lightweight sleeping bag liner made from soft, slightly stretchy 15D DTY nylon. Thanks to DTY (draw texturized yarn) technology, fabric has a soft, cotton-like feel that makes sleep setup feel more comfortable and closer to home bedding.
Ultraliner helps keep sleeping bag cleaner, stays easy to wash, and dries quickly after use. This is especially useful with down sleeping bags, as it helps reduce how often bag needs full washing and can help extend its service life.
Relaxed fit gives more room for a comfortable sleeping position. Buttons at shoulder area make it easier to get in and out, and also let you put your arms out to zip up sleeping bag more easily.
