One of the straps on the system broke so I needed to get this replacement. The system is indeed identical to the one on my Boost helmet but replacement took a bit of experimentation. My biggest concern is that the helmet straps interlace with the retention system but to recreate that on my new retention system, I would have to somehow undo all of the straps in the helmet, lace them through, and then put everything back together. If this doesn't sound daunting then let me mention that it is nigh impossible to undo the straps to begin with. I certainly couldn't manage.
