And therefore the sun can shine through the cut outs -vents and can burn your noggin , like my old mate ,
Yep that’s why I wear sunblock
Not at all , whilst out in the road today , about 17 m to test out drive train mods I noticed a lot other riders had long sleeve tops on , I didn’t put mine on until I had to walk through Richmond Park and it started raining ,
but I will add I do not wear Lycra , cotton type t shirts and similar tops , I do have a Lycra top that says it can somehow absorbs sweat and vents it out, I’ve never put it to the test ,
