Descended from our popular Kelvin 3.8, the Reactor 3.8 is lighter and more compact, thanks to a tapered shape and strategically cut-out foam. The 3.8 is in the middle of the Reactor series thickness-wise and warmth-wise. It’s a good choice for four-season travellers wanting minimum weight and bulk in their packs, or for three-season users wanting some extra insulation and cushioning.

• Face fabric is polyester.
• New, non-slip surface on the underside prevents sliding in your tent.
• Middle section foam has horizontal cut-outs only, to maximize insulation value at your body core.
• Foam in the head and foot area has both horizontal and vertical cut-outs, to minimize weight and packed size.
• Oversized valve makes inflation and deflation easy, and closes with a single twist.
• Includes stuff sack and repair kit.
• Note: Dimensions shown on the stuff sack are for deflated pads, and give you an accurate sense of the packed size. Dimensions on mec.ca show the inflated size. These are the true size of the sleeping surface.
