I have a nanopuff jacket which I've worn almost daily through two seasons. I've absolutely loved it. I've washed it twice. While it's still in great condition, the wear is starting to show. Some of the strings that form the pattern are popping off, occasionally a strand of insulation sneaks out of a seam, there is pilling at the cuffs, and there are a couple of micro-rips at my cuffs where you can see the insulation upon close inspection. Because of this I started considering Carhartt or LL Bean for next season or maybe season after next, but then I remember Patagonia guarantees their products. I'll get it replaced if I can!
