I just installed a pair of Frogskinz shock well vents and am wondering about durability? They don't have any outer protective layer and I'm wondering about something poking thru at some point even though I don't do a ton of off trail riding. I found the 2coolair vents online are about the same size and have tougher outer membrane that might be worth putting over the top. Anyone have these on their sleds? Results? Any input would be great! Thanks!
