A few years back a friend and i were riding in what we thought were gonna be spring like conditions,so we ditched our hoods and headed up the valley into the backcountry,all of a sudden were into fresh powder,and we opt to go back for our hoods,seeming our sleds are gonna get sewered with snow now if we dont.
2 hrs later my friends clutch, primary, grenaded and sent shrapnel everywhere,looked like someone let a shotgun go inside his hood,pieces came thru the hood ,out the side underneath,every where.He said it was one of the loudest things he heard,it half deafened him for a few days.
point is i think if we didnt put our hoods back on, it could of been devastating,possibly fatal.
there's really no maintenance that could have prevented this thing from letting loose...
