I've got a Biltwell Gringo helmet and I like it -- not too closed in and looks sort of cool as well. On slower back roads (which I prefer) having the open front is fine. But when there is a need to ride 45 mph or faster, the wind does get tiring. Biltwell offers a bubble shield or a "blast shield" -- both snap on to the helmet. The problem with that for me is that I wear glasses, and adjusting them (or itching my face) at a stop sign or whatever is quite awkward. The whole thing has to be unsnapped and then re-snapped while the helmet is on my head. I saw a sort of goggle/shield called the Loup that Ruby makes for their helmets. It costs $200 and of course is custom fit to their helmet. Seemed like I could make something similar for the Gringo that would be easier to put on and take off. Here are some photos of how it was done -- material cost probably under $30. The shield itself is .040" lexan (actually a Biltwell "blast shield" that I cut up). First I tried using .090" lexan, and then .060". Both were too thick to be curved and held in place by the band. Pre-forming the lexan using heat was very difficult and I failed (using both heat gun and oven). So the .040 lexan worked best. I did not put trim around the edge as the Loup has, because it did not seem necessary and was cleaner without it. The band is a piece of shock cord (a thin bungee basically) from a camping store. Green webbing is from some keychains. Snaps are from the hardware store. In the first picture, you can see a black rubber grommet put around the middle snap on the helmet. This is to provide a place for the shield to rest when it is up and the stickiness of the rubber keeps it from slipping. It is necessary to have a retainer at the back of the helmet to hold the band, or it will slide off the helmet. I made this one from a piece of .060 lexan (as I had plenty left over) that was bent and cut. Nylon webbing was glued to it and some snaps put on it. The retainer slips into the back of the helmet between the foam and the shell, and comes out easily enough when not needed. This could probably use some aesthetic and functional improvement, but it works for now. The shield really seals well around the trim on the front opening of the helmet, and works great at speed. Not as easy to use as a flip-up shield, but it is nice to have it gone when I don't want to use it. It fits in a small tank bag.
