Isn't that wild!?! Their sizes are so weird. I assumed there would be a slight difference between the "kinds" (for lack of a better word). I think the ones i ordered were "ultra ", and i saw a few different (quest and vibe). But you would think that if the fit were so different, there would be obvious explanations to that fact. No such luck.
My grumblings have nothing to do with quality. I just ordered a size too big with no way of knowing otherwise. I guess with underwear, I kind of assume all XL's are going to fit about the same, minus a few variables (cut and materials, etc).
The size issues are no reflection on Mass Drop. The product just fits differently than other similar brands. The shipping issues with the last SAXX underwear drop, on the other hand, I blame completely on Mass Drop.
