Stay comfortably warm on chilly nights without bulky gear. This ultralight liner adds cozy insulation and packs down small for travel.
Cold nights on the trail can ruin an otherwise great trip when your sleeping bag alone is not enough. This liner solves that by adding a lightweight insulating layer that boosts warmth while keeping pack size minimal. Its soft, brushed surface feels gentle against the skin and helps trap heat for restorative sleep. A full-length design accommodates taller users and can be zipped together with compatible liners for shared use.
