After trying 4 different windshields I thought the Calsci was the winner. Rode in pouring rain for 3 hours Wednesday. Was getting hit with water in the chin (full face helmet). Evidently, the air the windshield lets thru it's hole is causing water to come off the top and rise up to my chin and then running down my neck. My shirt had a wet front racing stripe directly down the middle. My vstream didn't do it in the same conditions so I figure it's the windshield design. Vstream was purely a looks thing to me although it had some buffeting at my head. Found different helmets affected that but I want to be able to wear any of them any time. Having the shield cracked eliminated it as well so it's the aero of the helmet I figure. Puig touring is on the way. I like the looks of it better anyway so we shall see. I really liked the touratech but couldn't get past all the flaws in it they said were normal. I just want the hammering off my helmet without the water in the face. I'm really not that difficult. Thinking I should get into the windshield business.
