The Easton Stealth RS Player Pants are designed for elite players looking for maximum freedom of movement. Each element of the RS pant is crafted to work in unison to allow full range of motion while remaining lightweight and protective.EPP foams (think professional model airplane or vehicle bumper foam) and Poly Carbonate plastics make up the protective elements in the hips, thighs, and tailbone areas. These foams and plastics were chosen due to their lightweight and energy dispersion properties. Further protecion is achieved by segmenting each protective element so that it moves with the body in motion. Reinforced lower-spine and front belly pads round out the protective elements found in the RS pants.Mobility wise, the RS pants are on point with segmented pads (see above) and stretch zones located in the front, back and hip flexors. These zones are designed to stretch and move with the body, thus reducing body/pad friction during play. The split shell design strategically combines highly durable 840D, 420D and textured nylons with ventilated mesh zones to optimize performance. The fit of the Stealth RS pant is designed to fit snug to the body with reduced bulk and weight. The fit is improved with a unique 2-way belt system that anatomically sits on your hips to keep the pant securely in place, increasing your comfort level and overall performance. Enclosed leg zippers with mesh inserts further improve fit and allow for both cooler playing temperatures as well as easier on/off access.Overall, the Stealth RS Player Pants remain true to their roots by offerring a complete package of lightweight protection that will not get in the way while you're flying down the rink.
