ColumbiaUnisex Helvetia 14L Backpack, Dark Stone/Shark, One Size

I’ve been going crazy trying to figure out the source of the white marks appearing on my jackets. At first, I thought my winter coat was getting damaged in the wash—but when the same marks showed up on my brand-new rain jackets, I was completely confused. I finally realized the culprit: my little white book bag. The marks only appear on the shoulder where I carry it.Ironically, I expected a white bag to be high maintenance because I thought it would be hard to keep clean—but instead, it’s been making my clothes dirty. I haven’t been able to get the marks off, so now I have three damaged jackets.I'm really disappointed. Although it's a small bag (for size reference, I placed a women’s size 8 Croc next to it), I loved using it as a day bag. Unfortunately, I’ll have to replace it, which feels like a waste of money.Also worth mentioning: the bag's texture becomes a problem in the rain—it takes forever to dry.
