most leathers i see are you Euro size.
i wear a 36 pant and i ended up getting a
a size chart i found says a 34/35 waist is a 52. i tried those on ( 2 piece) and they felt good. but i couldn't zip the zipers up for my calfs(sp) ended up getting a 54 pant and 54 jacket.
best thing to do if your going to order it on-line. is go to a store that has what your looking for a try the suits on. i did that with helmets. i wear a "L" with scorpion but a "M" with Shoei
and i did that with my boots. went to cycylegear tried on like 10 different style and sizes and ordered them on line.

they couldn't beat newenough.com's price on Sidi's
