First the construction is excellent, and for me 6' 150lbs the fit was spot on. The material stretches well, so Im guessing it would fit larger riders too. If you are looking for the absolute minimum protection to wear under a jersey, look no further. If you want any type of substantial protection keep shopping. the padding is very thin, on the gray areas of the front of the vest I can run my finger across the padding and count my ribs. The center padding is a bit stiffer, but still thin. There is no padding at all on the back of the vest. the sides protection is minimal. Padding in area of neck brace can be removed. I kept the vest just to wear under a plastic roost guard for slight extra protection. this vest is better suited for sliding into home base than to take roost or an mx crash. Excellent design, poor protection.
