I thought my Guner was great as far as comfort and how quiet it was in freefall. I say was because I had one of those metal seatbelt type chin straps and during a recent jump, it came undone and flew off my head.....at 9000' ft., losing both Helmet and Pro Track. I know it was latched in the plane and I know I did not bump it. Bonehead claims they have not heard of this happening, but upon my "accident", I have heard otherwise. I haven't decided if I will buy another Bonehead yet. The Guner is definitely very comfortable, but I am not sure I want to buy another helmet with issues like that. They have changed the chin strap, making me think they knew of problems...... For any new buyers....just be cautious of that seatbelt-type clasp.
