Saw 45F in the mountains the other day, with a wet fog and 100 yard visibility. Had my Tourmaster mesh on with a fleece underneath. Not nearly warm enough.
Rode with MIkeMike on Monday up to 9,500 feet elevation. Low temp around 60F and my new Teiz Lombard suit with all the vents open was perfect.
Riding home at 85-90 mph, suit was perfect with the vents closed.
Bring mesh if you're at low elevations or by the coast, but definitely keep the liners handy. Mesh gloves are fine if you have hand guards,if not keep a pair of glove liners or non-mesh ones with you.
You'll probably survive without heated gear, although temps below freezing are possible, layers Should work fine.
Sunscreen or a bandana to prevent sunburn on the back of your neck.
Roll of toilet paper and you're set.
Young enough to know I can. Old enough to know I shouldn't. Stupid enough to do it anyway
