I rode last summer with a mesh jacket w/armor(a tourmaster draft)in 90-100 degree weather in eastern washington with only t-shirt under and was fine..just drink 16 ounces of water every hour to keep hydrated.This summer I bought a triumph raptor 2 mesh and will be fine wearing it also.BTW..last summer after riding 6 hours from the Nelson Raid(90+0,when I crossed snoqualmie pass to 75 degree weather I had to stop and put long sleve fleece shirt as I was cold!!All this gear has elbow,shoulder and back pads!!
