I bought the Woolies before these, and absolutely loved the Woolies. I bought the Balance boxers briefs thinking that the form fitting nature of these combined with the wool would be amazing. I was wrong. These ride up on the legs and don't fit my rear end either. I had bought the Woolies in a medium, so naturally, I bought these in a medium as well. They are way too small. So, I returned them for large. Those still ride up and feel horribly uncomfortable. I'm sad to give a poor review, but I have tried these and given them a chance. Get the Woolies. You won't be disappointed. I can't say the same about these.
