Guardian Sports offers a 6 month limited warranty and you can contact them for your available options. Guardian is a soft product similar to a sweatshirt or arm pads. The durability of Guardian Caps depends on the player's size, skill and location as well as the number and severity of impacts. The Guardian Cap may tear if used on a sled or on an object that could cut or damage the material. If the protective cap is cut on such equipment, it will not be replaced. Hats should be checked before playing.
Guardian Sports is everything. The elastic attachment straps stretch to fit all helmet sizes, makes and models. The strap goes through the mask and attaches back to itself. If you are having trouble wearing a specific face covering, please call them. The outer material is similar to an Olympic swimsuit designed to be waterproof, and the inner padding is a closed-cell material that does not absorb water.
You can see that independent research actually shows the opposite. Adding Guardian Sports at 90°F+ insulates the helmet and keeps the head 15-20°F cooler. The reason about it is that while polycarbonate conducts heat, the Guardian Cap's foam doesn't and is more of an insulator.
The Guardian Sports's team wanted to create a training ball that didn't affect muscle memory so you could practice like a game. The PEARL NX ball is the same size, weight and softness as the official PEARL X and LT match balls, so players no longer need to use heavier, smaller or harder balls for practice.
