KZO x Master-Piece | Glacier Collection Backpack | $732
First of all, this bag looks great. Second, I happen to own a wool messenger bag, and I think it looks great too. The only problem is that it seems inappropriate unless it is cold and windy and snowy. See, I bought my bag thinking it looked great from a picture I saw on the internet, then I felt like a doofus wearing it when it was 100º out in Los Angeles. Also, it tends to pill (like a wool sweater), but this can be a good thing… It is fun to pick them off during a boring class.
