The Australian brand Sea to Summit specializes in producing lightweight and functional products for adventure tourism. Introducing the super lightweight, compact, and warm Reactor Thermolite sleeping bag liner by Sea to Summit.

This sleeping bag liner is made of insulating Thermolite fabric, which consists of hollow, breathable fibers that provide exceptional warmth. This material adds up to 12% to the thermal properties of the sleeping bag (for summer sleeping bags) and up to 6% for three-season ones. On warmer summer days, the liner can be used on its own.

The Reactor Thermolite liner is designed for mummy-shaped sleeping bags and measures 216 cm x 80 cm. It not only provides additional thermal comfort but also maintains the hygiene of the sleeping bag by preserving its cleanliness and protecting it from abrasion and damage. Additionally, Sea to Summit designers have included a drawstring hood that helps to better retain warmth during cold winter nights.

The Reactor Thermolite liner by Sea to Summit comes with a transport sack made of Ultra-Sil material, which is waterproof and highly resistant to tearing and abrasion.

We recommend the Reactor Thermolite liner to all outdoor enthusiasts who value every gram of their gear.
