Sea To Summit Reactor Fleeceweight Sleeping Bag Liner - Mummy - Short

Sea to Summit

Add extra warmth and comfort to your sleeping system with the Sea to Summit Reactor Fleeceweight Liner . Designed for cold-weather adventures, this lightweight liner uses insulating Thermolite® Fleece to trap and reflect body heat, providing an impressive boost in warmth without the bulk of a heavier sleeping bag. The grid-fleece construction uses Thermolite® hollow-core fibres to capture warm air and help retain body heat, adding up to 8°C / 14°F of warmth to your sleep system. The soft, stretchy fabric moves naturally with your body, while integrated armholes provide greater freedom of movement, making it particularly comfortable for side sleepers and those who tend to move around during the night. The liner fits inside any sleeping bag and can be snapped into compatible Sea to Summit sleeping bags for a secure fit. This helps keep the liner in position while also making entry and exit easier. Practicality is just as important as warmth. The quick-drying fabric is easy to clean and features HeiQ Fresh odour control , helping the liner stay fresher during multi-day trips. By providing a washable layer between you and your sleeping bag, it can also reduce how frequently your sleeping bag needs to be washed, helping preserve its insulation loft and long-term performance. Compact and versatile, the Reactor Fleeceweight Liner is an excellent choice for cold-weather backpacking, hut trips, winter camping and bivvies where additional warmth and freedom of movement are essential.
