How do Assos sizes relate to waist size?
The size chart gives height measurement. I am 175cm (5' 9"), which would make me size medium. But I have a 90cm (35") waist. Would I actually fit into medium? Conversely, would Large be too big, because designed for a taller person?
I would recommend medium - especially if you're looking at turning your 35" into 33-34", I'm 177cm/73kg/32" and the medium is absolutely spot on, I would say the extra 2cm I have on you would allow for any belly curves etc. You want the medium so the pads go where they need to. I have a large pair (first pair, bad size choice) and notice that I have to move the crotch forward to get the pads in the correct position, so I now use my mediums over the large.
