They are good to deal with. After seeing their stuff at the IMS shows I ordered a pair of Ezeon pants online. I did not know they were sizes as overpants and bought a size too big. I emailed them and they sent out a size smaller the same day...before I ever sent back the other ones.
...and the pants are nice (although a bit warm, but I bought them to replace my leaking HT overpants so they'll work great as cold weather gear).
