I used a trisuit for a year and I liked it. the fit wasn't perfect, meaning it fit with the exception of my height, like it was made for someone with the same body juts a bit shorter. if you get a perfect fit you might like it a lot. you feel kinda like a super hero in it.
my take away from the experience was that I liked the thinner tri short type liner. also it started to tear cuz I was too tall for it. very happy now w my zoot trishorts and I can wear whatever I want up top
