Hey guys, just getting some extras like a fresh set of rain gear first of all how does that sizing work on the Nelson Rigg stuff? I am a Shrek, at 6 foot 265lbs and 53 inch chest. What size setup of theirs works for that?

Secondly, anyone try out those evaporative cooling vests? I am making the 900 mile run to Sturgis for opening week and was wondering how those functioned. I will be wearing the long haul gear until I get there, full face helmet and Klim Induction jacket, which breathes well but in that summer heat, wondering if those vests actually work. Any input is appreciated.
