Sand Wash Joggers

Bought these about a year ago and they have already started showing signs of extreme wear (thinning in multiple places)! The patches I showed were the largest ones; however, they are consistently across all the cuffed/elastic portions and I can see it on the non-elastic portions as well. I really didn't wear them that often since it gets hot where I live quickly, and I always follow the care instructions carefully (no fabric softeners either). Don't get me wrong, they feel and look great. I've gotten a lot of compliments on this set. (I also bought the matching half-zip.) The material is nice and lux, but it's disappointing to see that an item as expensive as this is not durable. Also, I bought this when I was about 128lbs. I'm probably about 140lbs now, and it still fits me perfectly. I'm 5'5 and it is a little long but still looks nice and slouchy.
