Okay, it's brand new, it fits great. And I believe I have had similar issues with other helmet straps. They abrade the living daylights out of my chin!! Solutions? Obviously, loosen it. I usually wear some kind of balaclava and/or neck gaiter, but we're getting out of that season now, and I can get by without those. Anyone have any quick advice, esp beyond loosening the strap to insecurity? Something I can put over the strap material? Thoughts, ideas?
Abraded the whole bottom of my chin, which is now charmingly but lightly scabby. Real attractive (like sunburn peeling). Will begin search for something as suggested above, i.e., Turtle Fur (have a neck gaiter with this brand name). Not into sewing 
I wonder if you have an errant edge or thread that shouldn't be there, that's abrading your chin. I skied without my neck gaiter this past weekend with my Fuse helmet, and I had no discomfort at all. I wish you were closer--I'd offer to rig something up for you.
SPF 100+ or bust for me! Kind thanks, though. Am sure I'll be able to rig up something. Looking right now like I got a sunburn on my lower chin and am peeling! Strange...
