Sleeping Bag Liners

A sleeping bag is the next-to-skin layer in your sleep system, or your hygienic sleep sheets when you travel. Sea to Summit liners use materials including Thermolite, Coolmax, Tencel and Silk to provide maximum comfort: wicking moisture, adding warmth and keeping your sleeping bag clean.


Used with a sleeping bag, a liner is a great way to protect your investment – using one on every trip will significantly cut down the number of times you need to wash your bag. If you’re traveling, a liner means you always have hygienic sleep sheets, great in situations where you may be offered less-than-pristine bedding. 

Liners increase your sleep comfort – the Tencel, silk blend, Thermolite or Coolmax fabrics are soft against the skin, they wick moisture and – when needed- add warmth. They are also easy to take care of.

Always a good addition to a sleep system, Sea to Summit’s design features add functionality that makes them simply indispensable.
