Brand new to triathlons and these were the first pair of tri shorts I've purchased. While at first skeptical about the small, flat chamois there have been zero issues with the giggle berries while riding (up to 40 miles so far) and minimal chaffing on the first run, which was fixed with a little body glide and have had no subsequent issues since on that end. I've never been much of a swimmer and have never worn jammers (or twinkie smugglers for that matter) before but these have been a game changer in the water for me. They feel fast and help bring the back end up with that fast feeling translating into fast-being on the stop watch. The compression is nice and the short length doesn't lead to any bunching. I haven't tried any other tri shorts but frankly don't see the need. I'm short and have thick legs (calfzilla, legatron, etc.) and am very happy with the fit and performance plus added vanity points for showing off the quads and being able to tan a bit above the knee.
