hey, just thinking of buying the Sutro S but I'm not sure if it will stay on during downhill sessions or it can fall off easily. It doesn't have the Unobtanium on the temples like the Radar EV does. Anybody and suggestion? thank you :)
I haven't had any issues when charging hard on enduro at least! Haven't tried on DH and with a full face helmet, but at least they have stayed on really well on me thus so far!
