I have been using this sleeping pad several times outdoor and indoor, and I am with her couch properties (if one may call it so because) satisfied. I especially like its length, because with 2 m length it goes well beyond other products that have 1.80 m as standard.
Negative to mention is actually their tenderness - stones, sticks and what do I still not only leave marks on the aluminum coating, even a simple discontinuation of the backpack when the mat is attached, can beat a real hole in the coat!
And for some reason (for the product now but nothing can) my cat is probably the smell of the mat and has done it chosen as the scratching post - all of which is of course another is conducive to the mat ...
Ultimately I vacillate 3-4 stars. But since I do in practice (eg. As sleeping in the open air at temperatures just above freezing) have done with this mat good experiences and your mattress is to have just for a cheap price, I stand by my 4-star rating ,
"More active" Hikers should however - already because of life - look for a more sustainable product.
Finally, I would note that confine my practical outdoor experience with this mat on missions in the highlands (Swabian Alb) and the spring to fall. So I can not comment on their use in the high mountains or winter here.
