I think the review is pretty much spot on. I have used it on my last tour in Europe.

I think it is quite annoying how much space this takes up in the pannier (although it is quite light). I guess that's the trade off for how comfortable it is. I was considering for my next tour just buying those cheap jansport backpacks (just a cheap regular backpack) that can be rolled up tightly and trying that instead. I am not sure about the different in comfort level but I think the jansport would pack smaller.

Any other thoughts?
