In reply to UKC/UKH Gear:
The mat looks more comfy than the mattress on my bed! It's a good point about width and tents, I've checked 2 person tents I've reviewed by putting my Thermarest Z Rest and Ridgerest - both 50 cms wide, thinking I've not met mats wider than that, so if they fit side by side that's a genuine 2 person tent. I doubt two Neolofts would fit in the two MSR (same parent company as Thermarest) 2 person tents I've reviewed, so that would be a major consideration.
What is side-country in terms of camping? 😄 I know it's a skiing term but not sure exactly what its camping meaning would be! Sleeping in your van at the side of the road below Stanage Apparent North perhaps? 😉
