Foldable Sleeping Mat

Pros:

Fits snugly and compactly into the German Rucksack. Well made, and durable

Cons:

Given how light the pack is, it does add a fair bit more weight. Having said that, it is still a very light package. It is also more for keeping you alive than comfortable. I have slept on a variety of surfaces in the past, I would say that it is like sleeping on a carpet or rug on the floor.

Overall:

This is worth getting if you want a mat that does the job, no fuss, and does not take up a lot of room. I would recommend this if you are backpacking, and might need to camp on the ground for a night or two. It definitely favours utility over comfort, so perhaps practice sleeping on the floor for a few nights, to get used to the feel, and if you can put up with that, then you shouldn't go too far amiss. As far as providing better support for the pack, I did not notice much of a difference personally, but that may be more due to the nature of how and what I pack.

I just purchased 2 of the German ruck sacks for me and my wife. I tried the ruck without the sleeping mat insert is was fine but I put the slapping mat in and it made a huge difference. Definitely worth getting especially if you get the German tuck sack.
