The Reactor Liner by Sea to Summit is the stretch-it-on, warm-it-up solution for boosting heat in every cold-weather sleep system!
Built with Thermolite® Pro technology using Far Infrared technology and hollow-core fibres, this liner traps and reflects body heat without extra bulk for serious warmth on chilly nights. Stretch-knit fabric and shaped arm openings allow unrestricted movement for natural comfort throughout your sleep, while the ergonomic design with a fitted hood delivers optimal warmth without extra weight. Snap connectors at the shoulders easily pair with Sea to Summit sleeping bags for quick, hassle-free entry and exit, and HeiQ Fresh odour control technology keeps the liner fresh after extended use. Machine washable construction simplifies care while reducing wear on your sleeping bag over time, and it's crafted with certified recycled fibres and bluesign APPROVED materials for lower environmental impact.
The Sea to Summit Reactor Liner is the stretchy, warmth-boosting layer for every alfresco sleep!
