Well finally bought my Schuberth S1 helmet. Fabulous.
I stuck Humvees stickers on:
They are incredible. In daylight you really cant see the black stickers, but at night time, put some light on it and they light up. The schuberth stickers are brighter, but they are white in daytime, humvees really are invisible.
Very well made as well, good cut and definition and separate well from backing, just like they were OEM.
With a bit of luck IŽll put the stickers on the bike tomorrow and post more piccies.
