Age and damp have finally made it impossible for me to get a good night's rest on a half inch thick piece of foam rubber, a standard self inflating kip mat didn't change the need to turn over every half hour to ease the pressure on my hips either. An alternative was needed or my backpacking days were over. I looked at the 10cm self inflating mats but they were all too bulky and too heavy to carry and then I wondered if the three quarter length would be a good compromise. I took a gamble and ordered the Ad trek. The price was reasonable and it arrived very quickly (amazing because I live on the well known 'Highland island' of Kintyre, but that's another story). I drove to the Lake District last weekend for two nights wild camping and took the Adtrek with me. It was light enough to strap to the outside of my pack and small enough to not make me look like an American student on a hiking holiday, but the real beauty came when I opened it out and inflated it. I laid out and opened the nozzle to release just enough air to feel myself sinking into it. When I closed the nozzle the mat retained its supporting rigidity yet had enough give in it to make me feel I wasn't going to spend the night on a sheet of plywood. Camping career now extended thanks to the Adtrek. Happy days.
I use this as extra padding for sleeping on board boats with hard mattresses. The 3/4 length is useful as boat bunks are often in an asymmetrical shape. While it adds extra padding, on warm nights, it is very hot & sweaty to lie on. I ended up putting a beach towel on it in order to reduce the heat build-up. I got the 3cm thickness one as I just need a bit of extra padding, not full body support, and wanted it to be lightweight enough to go in my sailing bag. Quality is sturdy, and like the green colour.
