If you want protection with good airflow, it is hard to beat KLIM mesh jackets. A little on the expensive side but I have had mine for 5 years (40,000 miles) now and it does not show any wear. I just wear a light tee-shirt under it.
Yes! out of all the "shirts" I am really liking these, and the Bohn armor.
Just be aware the Induction mesh jacket has a European cut so you may want to order one size larger if you have a gut. I ordered my size and it is a tight fit, not too tight but tight enough if I wear a heavy shirt, feel sort of like a sausage in a casing. Thin shirt or tee shirt it fits well and does not flap or restrict.
Same here. Last few hundred thousand miles I've worn fishing shirts to protect the skin from the sun. Too hot down here for mesh jackets behind a batwing. I've tried!
The PFG shirts are nice and loose, they let some ventilation in...When i travel in the summer i just carry a cooler with me and we drink big yeti type mugs full of water and ice. Hydrating is key.
Just an update, I found a summer "riding shirt" on Amazon the name of the company is Wicked Stock, I paid $58 + shipping, pics to follow, according to Wicked Stock "is a small team of entrepreneurs, designers, and skilled motorcyclists based out of suburban Baltimore, MY." anyway seems like good quality, it has a good snug fit, has level 2 CE protection and comes in multiple colors, I chose grey, haven't had the opportunity to take it out on a ride as we are dealing with some of Debbie's wrath.
