hey dudes, i'm buying my first harness online. i've used them before, but never checked the size...i have a 31"inch waist. Do i need a small or medium? I'm looking at the tabu waist.

thanks

Medium with a 10" bar should do it. The harnesses run a little on the small size so choose a size one size larger than what the charts say, especially if you intend to wear it in the winter.
