A Thermolite Pro liner that adds meaningful warmth to a sleep system while staying small enough to carry without thinking about it.
Thermolite Pro uses Far Infrared technology and hollow-core fibers to trap air and reflect body heat back at you. It adds warmth without the bulk of stepping up to a heavier bag, which makes it a sensible way to push a summer bag into shoulder season.
The cut is ergonomic with a fitted hood, and the stretch knit with shaped arm openings keeps you from feeling wrapped up. Snap connectors at the shoulders pair with Sea to Summit sleeping bags so getting in and out does not drag the liner with you, and HeiQ Fresh odor control keeps it fresh on longer trips.
