I wear the XL Castellis and they're tight. They don't do a XXL. Does anyone do a good knee warmer in bigger sizes?
How big are you talking?
I have a set of Giordanos that are nice and they seem pretty accomodating (stretchy) AND they stay put, and I have a set of Pearl Izumi that I think are slightly too loose for my taste. Both are XL. I'm 6'2 220 and the selle italia dude said my thigh measures out at about 62 cm, if that helps.
Aerotech makes an XL-XXL sized knee warmer. Size chart says 19-23 inches for thigh size. One of the reviews complains that they are too big for the listed size L, aerotech seem to go to the bigger side of a sizing.
Measurements will be necessary.
6'5" 116-118kg and XL Pearl Izumi fit me fine, almost loose.
