Runderwear Men's Running Briefs - Chafe-Free Running Underwear (Navy, Large (34" - 36" Waist))

These are basic polyamide briefs and in my opinion hugely overpriced. I mistakenly bought them instead of the merino ones from the same manufacturer. I'm rating them three stars because they are as described and very comfortable but they are thin, seamless and extremely stretchy so they offer practically no support. The "cup" basically yields under the weight of your bits.
