I hear they are on the smaller size, and people have said to order a size up. That would put me at a Small (I wear XS in everything else). But according to the Assos sizing chart, I am exactly where I should be... XS.

Anyone have experience with these?

I found a British site that is selling them for $130(US). With $15 shipping, it still makes it cheaper than the $170 list price you'd find here. Trouble is, if it doesn't fit it'll cost a bunch to return it... so I have to be extra careful about picking the right size.
