Okay, in the greater scheme of things this is a pretty wimpy dilemma. But thanks to Barley's bed and the wonderful storage space beneath it, I have room to take two sets of riding gear. From Vermont to Oregon via the Great Plains, Badlands, Black Hills, Beartooth Pass, backroads of Montana, Lolo Pass, Mt Rainier, St Helens, Mt Hood, Crater Lake, NorCal Redwoods and back up the southern Oregon coastline I'll probably experience everything from brutal heat to torrential rain.
I'll definitely be taking my mesh for the hot sections: RevIt pants and BMW Airshell top. I'm not a big fan of removable liners, but they work well even if it feels like a sauna in a warm rain.
But for cooler climes and gentle rains I'm torn between my Onesie Stich...and my RevIt Sand pants and Cayenne jacket with liners. The Stich is more comfy as long as I'm moving, will keep me dry enough in a drizzle or a gentle soaker, but is less than optimal at rest stops when I have to take Barley for a walk to pee and supplement his diet with small rodents.
Must sit down and do a cost-benefit analysis...
