Sea To Summit Coolmax Adaptor Sleeping Bag Liner

Jump to: Our Verdict / Features / Specifications

The Coolmax Adaptor Liner is a versatile sleep system that can be used by itself or as part of a layered system. The Coolmax fabric speeds moisture to the outer surface.

Sea to Summit says

A climate control travel liner specifically designed for warm or humid conditions. The Coolmax Adaptor, as the name suggests, is a liner that adapts to varied temperatures and humidity because it is made from Coolmax, a proven moisture management fabric, giving you a more comfortable night’s sleep.

Our Verdict

Coolmax is well known to wick moisture away from the skin leaving the wearer cool and dry – this sleeping bag version will do the same while you rest. Could be used on its own if camping in a warm climate.
