I bought the pants, because I was hoping to get a good rain-proof and breathable rain pants. Unfortunately the is not so. The review of John Teuber "ride in all weathers daily 25km to work .... as me the new rain pants never let me down ... hardly sweat, even on longer trips ... good fit, especially for large cyclists, by extra long leg length ... so all in all good product .... Buy !!! "had me convinced me to choose those pants. Unfortunately, these pants are not really breathable, honestly I have not had rain pants where I sweated so much as in this. I ride about 25km a day to work in all weathers and my old rain pants (25) has unfortunately given up the ghost. The rain pants for 25 had unfortunately left on the sides zippers penetrate water repeatedly with heavy rain and was so not 100% waterproof when it was pouring right, but at least you have not sweated so much in her. From such an expensive brand pants I would have expected more. Furthermore, I find sizes details as L, XL and XXL always very misleading. My old XL was in size 56, and the VAUDE XL in 54th As for the water density I sadly can not say, because my pants are so far become increasingly numb to wet in the rain pants (not breathable) and yet was no heavy rain. To fit I must say that it is great. I can recommend but not.
