Review on Modern Men's Speed and Strength by Jay Mitchell

I live in Florida and the temperature fluctuates wildly these days - over 80's during the day, under 70 after sunset. It does the job - well under 80, over 80 you have to decompress a little. It's a bit chilly in the 60's but not cold. Great for as I often leave when the sun is up and come back when it's gone. Despite good ventilation, my leather jacket is too warm for RN day rides and my summer jacket feels too bulky. This is fully compliant.
