About the fit: As someone tall with very broad shoulders and lats, I must say that it's quite hard to find a suit.
Following the size chart, I ordered a size Small and it fits very well! Couldn't have asked for better.
For reference, I'm 1.79 m tall, 69 kilos, about 18% body fat, waist 71 cm, hips 97 cm, back 80 cm, chest 90 cm.
It is slightly pulling on my neck when fully zipped, and there is more space to fill in the belly and glute area.
About the quality and comfort : Yes! Surprisingly, while being very thin, it is very comfortable on the bike. I haven't run with it yet nor swum, but I'm sure that it will be no issue. No weird seams, the fabric is sturdy and breathable. It does show sweat, but dries extremely fast.
I hope this review finds the right person and helps determine if this is the right suit for you.
