These are great shorts for a tri! I’ll be wearing them in my first one in a week (assuming it happens). I’ve been wearing them for my training up till now.The bottle pockets are why I purchase these, which I’m not sure I personally have fully bought into them being as beneficial as I thought they were going to be. Even tied, the bottles tend to lightly pull the shorts down a little at a time. Easy enough to pull them up, but annoying. I usually wear without the bottles now.The shorts themself are great, even when not using the bottles! They are light weight and breathable. They also have the right amount of padding. The padding lets me do 50 mile bike rides with no real discomfort, other than expected discomfort for being on the bike for 3 hours! The padding is also light enough that running in these, you don’t realize it’s there!As for fit, I’m 6 foot and weigh about 205. I normally wear 34-36 pants and ordered an 2Xl and would consider them a great fit. They are snug, but not cutting off any circulation.Overall, I will be purchasing another pair of these to wear!Update: I have since bought another pair of these shorts as the first pair have worked so well. These shorts are a perfect pair to run and bike in (haven’t done much swimming). The padding is small/thin enough to run without feeling it, but also provides plenty of padding for 50+ mile bike rides.
