The CCM S19 Tacks AS1 Senior Shorts remain one of the best on the market for protection and coverage. D30, CCM's premier smart foam, reinforces two major areas that take on high and low energy impacts, the spine and hip. The hip caps utilize CCM's JDP construction that disperses impact energy away from the hip joint while D30 absorbs the energy. The floating spine guard offers players a ton of coverage and protection to the lower back. The spine guard attaches to the tailbone with Velcro, allowing players to adjust the height of the protection in order to obtain the perfect coverage. D30 reinforces HD closed-cell foam, and then thick medium-density foam rests against the lower spine for incredible comfort.
