Add warmth to your sleeping bag or use this fleece thermolite liner as a stand alone summer sleeping bag. Constructed from a lightweight combination of Thermolite and polyester fleece material, this liner is designed to trap air inside its fibres to help retain warmth and keep you nice and cosy during the night.
The Thermolite fleece liner is the warmest in Sea to Summit’s Thermolite range and adds warmth to your sleeping bag, as well as keeping it clean. If you’re using the liner in warmer conditions, you can use it as a summer sleeping bag. The fleece liner includes an adjustable draw cord hood and foot section. Packing down to 14 x 9cm in size and weighing a lightweight 420g, this liner is much smaller than other fleece liners and is also warmer.
