The M-Tac Eva Knee Pad Inserts are designed to protect your knee joints without restraining movement and maintaining agility. Made out of 0.3" EVA foam. This is a soft, memory-foam polymer material. The kneepads return to their geometric shape even after long periods of deformation. This allows the pads to follow the natural movement of your knees. The kneepads have visible cut-out lines, allowing you to tailor them individually to your size. Also feature ergonomic crevices for additional comfort and holes for improved ventilation. While working, or resting on your knees, these kneepads will protect your joints from any mechanical and pressure damage. Due to the thought-out construction, they can be quickly and easily adjusted to fit any pants with an internal compartment for kneepads. Military-grade protection with no obstruction of mobility for everyday wear or tactical combat missions. Material: EVA foam Weight: 0.13 lbs (58 grams) Dimensions: 10" x 5" х 10" (254 x 127 x 254 mm)
