I've been lurking around the forum reading and learning and trying to make up my mind on if I wanna try saddle hunting. I've finally decided to take the plunge. Going to place an order for a mantis and the whole rest of the whole shebang from tethrd. Anyone have any insight on how the sitka heavy fanatic bibs fit under the mantis. I wear a L didnt know if I should size up on the saddle. Thanks in advance for any comments and glad to be a part of such an active forum with so many awesome members
