The Sea to Summit Reactor Midweight Liner is designed for backpackers, travelers, and hut-trippers who need a reliable thermal boost without significant added weight. By utilizing Thermolite Pro technology, it effectively adds up to 6 degrees Celsius of warmth to your sleep system while acting as a protective barrier to extend the lifespan of your sleeping bag. While it offers excellent versatility, users should note that the regular size is specifically optimized for individuals up to 185 cm tall, limiting its utility for taller hikers.

Yes, it can be used as a lightweight summer sleeping bag or as a travel sheet in warm environments, though it lacks the insulation of a traditional sleeping bag.
The regular size is designed specifically for users up to 185 cm. Users taller than this may find the length restrictive.
Look for internal snap-in loops near the shoulder area of your Sea to Summit sleeping bag.
No, the stretch-knit fabric is designed to be lightweight and compressible, making it highly portable for backpacking.
No, do not use fabric softeners as they can clog the fabric fibers and reduce the effectiveness of the odor control and moisture-wicking technology.
Ensure the liner is fully smoothed out before climbing in, or use the integrated snap points if your sleeping bag supports them.
Wash the liner thoroughly using a technical gear wash to remove body oils and reset the HeiQ Fresh treatment.
To set up, simply slide the liner into your sleeping bag. If you own a compatible Sea to Summit bag, align the snaps at the shoulder area to integrate the two units, preventing the liner from twisting while you sleep. Regarding compatibility, this liner works with any mummy or rectangular sleeping bag, though the snaps are proprietary to the brand. To care for your liner, wash it on a gentle cycle with cold water using a mild detergent. Avoid using fabric softeners, as these can impede the moisture-wicking and odor-control properties of the fabric. Always hang-dry the liner in a shaded, well-ventilated area to protect the integrity of the synthetic fibres.
