Both UVA and UVB are ultraviolet rays, different in strength, but the same in their power to harm. UVB rises and falls with the season’s heat. UVA remains all year, unseen and steady, moving deeper into the skin, a reminder that true protection is never seasonal, but constant.

This was my vision when I purchased the first iteration of your long sleeve shirts - a sun shirt type fabric with a hoody. Glad you developed this product. I used this the other day and was pleased with its performance. I did not overheat. I also did not find the need to apply chemical sunblock on my arm. I had the hood ready to go over my helmet had the heat become a little more unbearable. I found the fit better than the first long sleeve - oh so marginally looser. As a bonus, this old, ugly (seasoned?) cyclist felt good looking in this shirt. For the next iteration, please have three rear pockets just like other cycling jerseys. Or maybe side pockets. Good luck and keep on developing!

Runs a little larger than the tees, but the cinch at the hems makes it a good partner for bib shorts.

Not a fan of sunscreen, this shirt eliminates that need on my upper body. Such a good color, helps keep me decently warm during chilly mornings (california morning, so very mild) and not too hot on warm days. Dries fast. If I had the means, I'd buy like 12. Very good

It’s a nice sun shirt. Can be really helpful for longer rides or days when you’re outside for a long time.

Sure, a cycling jersey may be more aero... but I'm not racing and they look goofy for long mellow rides. This thing actually protects me from the sun and looks great. This shirt with a pair of cargo bibs is my go to kit.
