Sea To Summit Reactor Lightweight Sleeping Bag Liner: Maximum Warmth, Minimal Weight
Chasing the ultimate adventure demands gear that performs without weighing you down. The Sea To Summit Reactor Lightweight Sleeping Bag Liner is your essential upgrade for colder nights and extended expeditions, ensuring you rest comfortably and recover fully, no matter how far from civilisation you roam.
Unrestricted Comfort & Enhanced Insulation
Experience a noticeable boost in warmth without sacrificing precious pack space. The advanced Thermolite® Pro fabric in the Sea To Summit Reactor Lightweight Sleeping Bag Liner uses a powerful combination of infrared-absorbing ceramic pigments and hollow-core fibres to actively trap your body heat, adding up to 4°C (7°F) of warmth. This means more comfortable sleep in cooler conditions and a lighter load for your trek.
Key Features:
- Thermolite® Pro Technology: Lightweight and insulative, this innovative fabric with hollow-core fibres and infrared-absorbing pigments enhances warmth with minimal pack size.
- Freedom to Move: Stretch-knit fabric and specially shaped arm openings allow for unrestricted movement, providing natural comfort throughout your sleep.
- Technical Shape and Hood: The ergonomic design with a fitted hood delivers optimal warmth and comfort without adding extra weight or bulk.
- Odour Control: Treated with HeiQ Fresh, it effectively neutralises odours, keeping your gear fresh for longer expeditions.
- Quick-Drying & Washable: Essential for multi-day trips, this liner dries rapidly and is machine washable, simplifying maintenance.
- Sleeping Bag Longevity: By reducing the need to wash your main sleeping bag, it helps prolong its lifespan.
THE BOSS OUTDOOR VERDICT:
This is the liner to reach for when every gram counts and warmth is non-negotiable. While bulkier liners offer more insulation, the Reactor Lightweight excels at providing a significant warmth boost with an almost imperceptible weight penalty. On a recent multi-day trek through the high country, it made the difference between a restless night and deep, restorative sleep after a long day on the move. If you're serious about ultralight adventuring and demand peak performance from your sleep system, this is the upgrade you need.
