Got this in a Size Small. And as my first trisuit I was nervous about the fit (in retrospect should have ordered Small and Medium to just compare). But I ended up exchanging for the Medium only to learn that Small was the way to go so I exchanged back again. Drop off returns were super easy and shipping is also very quick.

On the Small I was worried that the shoulders were a bit too tight but the length, waist and pockets and legs were perfect. On the Medium the waist was where I saw the biggest difference. The suit didn't fit tight to my back at all and in general it was a fairly drastic size up. Hence switching back.

Overall the suit is beautiful, I'm happy with how easy it was to to test some sizing and am super excited for race day in this beauty :)

I bought this trisuit online without knowing what my size would be. After referring to the sizing guide I would have had to order a M although I’m usually a L for jerseys or cycling bibs. I ended up ordering L and initially thought it was too small because I couldn’t get in (almost exchanged it for a XL). But after a few tries, I managed to get in (quite difficult because the zip doesn’t go very low). Once it’s on, it fits me really well. For reference I’m 174cm and 74kg ish
