Ideal for summer trekking and hiking trips, the TRAIL MAT AIR is the go-to choice when light weight and a small packed size are the key priorities. Both have been reduced to the minimum. The mat has a special welded air chamber construction. The individual chambers are interconnected, which means the air inside the mat can flow freely between them, and the mat can flex and reshape to adapt to your body and sleeping position. The special construction makes the mat extremely comfortable to sleep on and stops it creaking and rustling when you turn over. The TRAIL MAT AIR is so light and packable that you can take it with you, even when you're travelling with super-lightweight kit. The special shape is a big advantage in tents with a tapered design - especially if your partner also has a mummy shaped mat. To stow the mat, simply open the valve to let the air out, fold it lengthways, roll it up tight and pack it in its pack bag. It takes up very little space in your rucksack.
