From my experience, the sizes run small (or I'm getting fatter).
I think they do run small. I tried the size 44 that was sized for my dimensions...and putting them on was like putting on those silly suits powerlifters wear. You know, they use those fricken tools to stretch them up and over.
I ended up with a size 48 that fits me perfectly but the sizes on the chart are way beyond my sizes. Well, over the last couple years I have been putting a little pudge on...but still.
Anyway, yeah, I agree with everybody here. I love the Teknic leathers I have. I have the Violator series. I've never worn a two piece, but the one piece is just awesome. You'd be surprised at the ease of movement. Just great. No complaints at all.
