Fleece liner Sea to Summit Reactor Extreme Thermolite - Mummy w/ Drawcord -Standard

The sleeping bag liner Reactor Extreme Thermolite by the Australian  brand Sea to Summit maintains the cleanliness of the sleeping bag and has the ability to increase its temperature characteristics by up to 15%.

The Australian brand Sea to Summit specializes in producing lightweight and functional products for adventure tourism. We present one of the warmest, most compact, and practical sleeping bag liners, the Sea to Summit Reactor Extreme Thermolite.

This sleeping bag liner is made of insulating Thermolite fabric, consisting of lofty, breathable fibers that provide exceptional warmth. This fabric adds up to 15% to the temperature rating of the sleeping bag (for summer sleeping bags) and up to 7% for three-season ones. On warmer summer days, the liner can be used on its own.

The Reactor Extreme Thermolite liner is designed for a mummy-shaped sleeping bag and measures 216 x 80 cm. It not only provides additional warmth but also maintains the hygiene of the sleeping bag by keeping it clean and protecting it from abrasion and damage. Additionally, Sea to Summit designers have included a drawcord hood that helps retain heat more effectively on cold winter nights.

The liner comes with a transport sack made of Ultra-Sil fabric, which is waterproof and highly resistant to tearing and wear.

We recommend the Reactor Extreme Thermolite liner to all outdoor enthusiasts who need to increase the temperature rating of their sleeping bag without having to replace it.
