Must say im glad i was wearing mine this week when i took a spill, the warmer weather had exposed lots of rocks in the trees along side the runs, but it had just snowed a couple inches so the rocks could not be seen.
Long story short, i went thru some trees tapped a few rocks, stoped me dead, did a tuck and roll only to hit my right arm/head/back off tons of big rocks. Hit my head so hard it sent my go pro flying into the trees.
Also i wear my goggle strap, coldgear blacava and coldgear "beanie" under my helmet, fits perfect with the ear pad piece removed. Feels better this way for me.
