Thermarest Synergy Sleeping Bag Liner

The Thermarest Synergy Sleeping Bag Liner is a sleeping bag sheet. It's a ‘meat bag’ that gives you more comfort, more warmth and prevents you from being in direct contact with your sleeping bag. This stretch fabric lining is soft and silky. It protects your sleeping bag (more hygienic) and provides 3°C more warmth.

The Synergy Sleeping Bag Liner can be used on its own or in addition to a sleeping bag, duvet or blanket.
