There's things you can do to make the heat bearable, from wearing dirt bike jerseys down to coolmax socks and undies. The mesh jackets with pads are going to be tested in the Sept. issue of Sport Rider mag. the general consensus is they will be ripped off in a crash and are no substitute for leathers or cordura, and that any area of the body not covered with protection will be at least turned into hamburger. It's hot in south Texas in the summer. My question is which is better, ride only morning and evening hours with full gear or be extra careful and ride all day in cooler attire? I think if your going to be at anything above 50% of your ability it's leathers time. A lot of guys don't ride when it's this hot. I think for touring or putting around leathers aren't nessesary but those could be famous last words.
