Product Overview:

If you're an athlete, you know the importance of keeping your head as safe as possible during training or playing a game. Now the 2nd Skull Pro Sports Bump Cap gives you an effective protective layer you can wear under most helmets that can help prevent injuries or trauma from collisions.

The sports cap is only 2 mm thick and works well with helmets designed for professional sports. Using money donated by the NFL, 2nd Skull has created the most dynamic option for protecting your head when playing sports or practicing. Preventing direct contact from the helmet to the head, the extra layer actually moves after contact and hardens, which can help reduce the impact on the brain.

    More Information

    Rotational force during high-speed impacts can put a lot of stress on the brain, head, and neck. Now there's a way you can help reduce the chance of injuries by wearing a protective cap underneath your helmet. Working with the NFL, the 2nd Skull Pro Sports Bump Cap is a game-changer you'll want to wear when playing professional or amateur sports.

    You can help avoid injuries to areas around your head by wearing this whenever you expect potential contact. It works by featuring a slippery surface that shifts the helmet at contact, which helps reduce the rotational force on the athletes head and neck.

    Ideal for practice or live events, you won't want to step on the field without the bump cap. It's thin enough to fit under nearly any helmet, and you can wear it as a skull cap when practicing non-contact sports. Other benefits include keeping you cool during exercise and wicking away sweat while training.

    Now available in sizes for children and adults, it helps keep athletes of nearly any age safe. The circumferences range from 19 to 26 inches, fitting nearly any child or adult. Coaches, parents, teachers, and trainers can work with athletes to find a size that best complements their helmets before the big game.

    For the most advanced protective cap of its kind, try the 2nd Skull Pro Sports Bump Cap the next time you play baseball, football, or another sport.
