Our Verdict
The Sea to Summit Reactor Extreme is an incredibly warm, versatile sleeping bag liner. It is made from Thermolite Pro fabric with infrared heat-reflecting technology and provides excellent insulation for cold-weather adventures. The mummy shape and drawcord foot box allow you to seal in warmth or vent heat if too warm.
The stretch knit fabric is breathable, and the HeiQ odour control treatment helps it stay fresh.
While not ultralightweight at around 350g, the warmth-to-weight ratio is superb. The compressible Reactor Extreme packs down small, making it easy to bring along on backpacking trips when you need that extra insulating layer.
