The Bauer Vapor X900 leg pad is the mid-level version of the its pro counterpart, 1X OD1N. Bauer incorporates pro-level C.O.R.Tech skin on the knee and calf plates, for easier and faster butterfly slides. Another key feature adopted from the 1X OD1N leg pads is the Tune Fit strapping: different from other Velcro systems, the strap is anchored where the top and bottom calf straps would be and attaches by Velcro at a single point at any position along the outside edge of the calf wrap. THERMO MAX liner is used in the leg channel. For knee protection, the pads come with X900 knee guards.
