Other than the want(no no, make that need) for shorts without seams in sensitive areas to rub me the wrong way, I splurged and got myself a good pair of garneau shorts. One thing I remember from the tag dangling off of them was "anti microbial chamois". I wear the same pair year round(0F to 110F) with washings about twice a week depending on "funk factor" as the missus puts it. In the 3 years since I've bought these there have been no uninvited guests invading my nether regions with boils and sores. Knock on cork.
