Icebreaker Men's Anatomica Running Briefs
Light, comfy, and works well
Used the Icebreaker briefs for running. No binding, good temperature control, good support; could hardly tell I was wearing them. Much better than compression shorts from that point of view. Also have worn them once as regular underwear and they were quite comfortable and again could hardly tell I was wearing them. Will plan to use them in the future for running and skiing/snowboarding, and also for light traveling. Purchased size M and have a 33-34 waist.
