First report: just one race, 100 miler in S. Dakota in a new (to me) RZR XP 1000.After racing GNCC-style races for 5 years with just a donut under the helmet it's nice to step up to real protection w/o it feeling that different.It's comfortable, easy to get it adjusted and fit to my pre-tapped helmet.Fits under my 3"" Master craft harness and I can twist slightly to see out the side of the RZR but this is the biggest difference, it really controls your head movement, just like it's supposed to. In the whoops, square edged hits and bad landings it's great, you're neck doesn't feel like it's getting wrung-out even though you still have to support the weight of your head.It feels really well made, a no-nonsense piece of gear.I'll update after more races but 5-stars so far!
