I really like this tech hoodie, but I was quite surprised to take it out of the wash one afternoon and spot a wear patch on the lower left side of the back--at this point, I'd worn it a day. I couldn't figure it out at first, then I realized that my backpack has actually worn a 3"x3" spot of rough and puckered material. (I've since also noticed this on a Howler shirt I have.) I would have expected these tech hoodies to withstand that kind of wear, or at least last longer without ultimately showing the wear. I will still wear it, but I ordered another and will be mindful about wearing my pack with it.
