Not familiar with 10-80, but Xelos is a grass roots all american made board short company out of Huntington Beach. They've got a ton of different prints and the guy who runs the place called me back last weekend (on a Saturday) so I could place an order. He was way cool and super helpful. I know they have a 9" inseam option on their shorts and that's pretty long.
Check them out. I ordered the Stealth Fanatic in Moss Green (camo) board shorts!
If you end up ordering, tell them Bruce from Seattle sent you.
