Product Details
This is the warmest liner Sea to Summit makes, and it's meant to add real heat to your sleep system when the temperature drops. The grid-pattern fleece uses hollow-core Thermolite fibers to trap warm air, so slipping it into your bag noticeably extends how cold a night the bag can handle. It's cut in a mummy shape to match most bags, and the footbox drawcord opens up for venting your feet or hitching the liner up so you can shuffle to the bathroom without taking it off. There's also HeiQ Fresh odor control built in, which helps on longer trips between washes. In warm weather it works fine on its own as a lightweight standalone bag.
