MoFiz Men's 3-Pack Woven Pajama Shorts 100% Cotton Plaid Sleep Lounge

I've been searching for these my whole life - longer boxer shorts WITH pockets. I'm thrilled. I bought two sets (after returning the first set). This review if for each set of 3-pk I received. Quite relevant. First set was a Medium and I wanted them bigger, so a man's medium should do the trick, but it didn't. Could've worn them, but not extra comfy like I want. The 2nd two sets (one order) I ordered size Large. These sets were two different varieties (pattern/color) of the same item. I wore them all from the first pack, then opened the 2nd pack. Wow. The 2nd pack (included black and white pair) were SUPER SOFT and now that I've worn all of them, different materal. Now I'm wondering how to get more of the soft material without buying the same pack. The tags are the same. The first set of large feels like regular boxer-shorts material, thin, a little stiff but comfortable and they've got POCKETS. :) (Pictured - red, blk, blu variety) The second set of large (with the with the white and black pair) feels more like a thin, extra soft flannel...kinda luxurious if you ask me. I'm happy with both, but it'd be cool if I could tell the difference when I'm purchasing. I love these things.
