I must commend Bonehead for their superb product and phenomenal customer service!
I recently received my REV2 and had issues with the fit. Specifically, although I was wearing an XS in the REV1, which I love, design changes made the REV2 a bit loose for me (small head, narrow face). After very informative and productive email conversations with Chris, a new liner, designed to fit my diminutive head, was sent to me in less than a week. Further conversations followed to check, and double check, the fit and my satisfaction with the helmet. A couple of additional edits, more velcro strips to hold the thicker liner in place and a smaller chin strap cover, make my REV2 perfect for me. Which is the point--even though I am an outlier because I am very small of stature, Bonehead worked to understand my needs, conscientiously communicated with me, and specially designed what I needed.
As to the product, I jumped with my REV2 this weekend and am thrilled. All the superlatives of the REV1 apply: ease of use, comfort, visibility, quietness, and security (that face shield isn't going anywhere). But there are even more great things to say about the REV2 because of the design changes. First, the helmet is even more comfortable. Because the chin/jaw area is streamlined, the head moves from side-to-side and down with greater ease. Second, the field of vision is fantastic, particularly when looking to the side or down. Next, it is even quieter than the REV1. Finally, airflow into the REV2 is improved, moving up the inside of the face shield rather than toward the face--an important consideration for those who wear contact lenses.
In short, Bonehead Composites, Chris, and the REV2 rock!
