I didnt know Kevlar had been around that long !!!!!
First time I ran into Kevlar was as the fabric covering on flak jackets in Vietnam, so that's been > 25 years ago, for sure.

(Gosh, it bites to be getting old.

)
I wore a half-helm but now wear a full-face. Though the full-face I have hinges so the entire front of the helmet swings up. Guess it's like a 3/4 face with a hinged face piece. Love it!
That's what I use — a Shoei Multi-tec, silver metallic. Like Melena, I wanted visibility, but I figured that silver might be slightly more visible and cooler on a sunny day. At night, who knows? Also, if gray and or hazy conditions, all bets are off, far as I'm concerned. (I'm a fair-weather rider anyway, so I try to limit my activities when visibility is impaired.) I try to enhance visibility by sticking on patterns of 3M reflective triangles (red for rear and sides, white for front). Looks rather interesting, though I can't attest their effectiveness.
BTW, that helmet is called a "modular" design in my area. I paused before buying because, though approved for safety by our Dept. of Transportation, modular helmets have not yet been approved also by the Snell Foundation. Hope I never have to find out I was mistaken.
The flip-up feature is great for eyeglass wearers. I find I have to crack the face shield slightly upward in cool or wet conditions to prevent eyeglasses fogging. Hope I never have a bee or wasp fly in.
I'll *always* buy a full-face helmet! I had my accident at age 17 & used up all my luck. Helmets weren't required, so naturally I never wore one. Near as I can figure, when I T-boned the car, I went over wind screen and car, made first ground contact with back of right hand, and did an instinctive shoulder-roll, breaking only three bones in my hand. (Didn't even have a bump on my head.)
