The Sea to Summit Reactor Compact Mummy Sleeping Bag Liner is the solution you need to boost the warmth of your sleeping arrangements for camping and hiking. When colder temperatures close in, this sleeping bag liner keeps you ready for adventure with Thermolite Pro fabric. This specialised knitted material features hollow-core fibres and infrared-absorbing ceramic pigments that capture and reflect your body heat, effectively boosting thermal performance. The inclusion of Thermolite EcoMade fibres, made from 100% recycled materials, ensures an eco-friendly approach without compromising on insulation. This cosy sleeping bag liner is moisture managing and treated with HeiQ Fresh FFL technology for effective odour control, maintaining freshness during long camping trips. It’s also a fantastic option to help protect your sleeping bag from the dirt and grime picked up during a day of adventuring on the trail, with the liner being easily machine washable. The stretch-knit fabric offers high adaptability, allowing the liner to conform seamlessly to any sleeping bag, enhancing overall comfort. The zip-free style contributes to its overall lightweight design and easy packability. Snaps at the shoulders allow you to slide into the sleeping bag liner comfortably, providing access to its generous opening. The Compact Mummy shape offers lightweight portability when heading to your next destination, and features a drawcord at the footbox opening. This enables you to adjust ventilation and allows you to ‘wear’ the liner at your campsite for warmth while keeping your feet free and mobile.
