Re: Jacket and Pants
My .02, the simultaneous needs of waterproof without placing a liner and comfort (=good air flow) in hot weather are mutually exclusive. The same barrier(s) that prevent water ingress also prevent good air flow. My example a BMW Streetguard 2, superb waterproofness, all the "gizmos" Gore-Tex XCR, TFL Cool system, underarm vents, when it is very hot the suit is hot, largely due to lack of air flow. For the really hot days I have a Motoport Air Kevlar mesh, however those same openings let in every drop of rain that falls.
When I take long trips I use the SG because I don't want to pack rain gear. I also tolerate heat very well, but everyone is different so you have to see for yourself how comfortable you can be in a waterproof suit when it is hot. It all comes down to balancing the levels of waterproofness and air flow. Happy suit hunting.
