Sea To Summit
Coolmax Adaptor Insect Shield Sleeping Bag Liner

Be the first to review



When it’s too hot and buggy to sleep, break out the Adaptor Liner.

In the hot, humid, and buggy corners of the globe, get a cool night's rest when you wrap up outside in the Sea To Summit Coolmax Adaptor Sleeping Bag Liner. When you sleep in this liner by itself, the Coolmax material transfers moisture out away from your body and stretches as you dream about the next day’s travels. The Adaptor also works with your sleeping bag to keep it dry and clean when the temperatures dive. And when the insects are diving and buzzing, the odorless Insect Shield treatment repels mosquitoes, ticks, flies, and fleas for scratch-free nights. The invisible repellent remains effective through six months of exposure to weathering or through 25 washings. The lightweight liner comes with an included stuff sack so you can throw it in your backpack without sacrificing food space.
