Perfect Fit

The stock liner with the medium retro lifer was a bit tight. Order the fit all kit and it arrived within a couple days. Now the helmets fits perfectly and I’m ready to shred! Definitely recommended getting if your fit isn’t right!

Hello! I ordered these for my watermelon s1 helmet and they came very quickly. Which is great because i was so ready to wear the helmet and feel protected! Idk if they were in the properly labeled bags, they might have been, but the color coding is what made sense to me. Im really glad my helmet fits properly and im stocked up on liners! Definitely recommend. Make sure your helmet fits properly!!!!
