Is there a difference between a bull riding helmet and a hockey helmet?
A (gridiron) football helmet is much heavier than an (ice) hockey helmet, and much thicker. A hockey helmet does not have the full ear protection and adjustable padding of gridiron football helmets, so that it is much lighter. A gridiron football helmet is the heaviest of all common helmets, typically weighing around three kilograms or 6.5 pounds. That is even heavier than a typical motorcycle crash helmet. This high mass allows gridiron football helmets to absorb impacts from very fast blockers who typically weigh around 150 kilograms or 340 pounds today and will deliberately and consciously ram into each other during line play trying to protect or sack the quarterback. In contrast, ice hockey helmets - other than those used by goalkeepers - weight around 0.8 kilograms with a plastic face mask and professional models can weigh as little as 350 grams, which is no heavier than a standard bicycle helmet. Ice hockey helmets do not have the thick adjustable padding of gridiron football helmets; instead, they have a thin, flexible polymer inside that absorbs repeated contact not from helmet-to-helmet contact as found in gridiron football, but from high sticks or stray pucks. <a href="http://www.weetect.com/products/helmet-visor/hockey-helmet-visor/">weetect helmets for hockey</a>

Why are there holes in the top of a football helmet?
There are two reasons for holes in a football helmet. Helmets have always had holes drilled in the crown area for ventilation. Body heat accumulates inside the helmet, especially during strenuous activity, and must be able to escape. The newer modern helmet styles have larger and better placed ventilation holes designed to keep the player from overheating. The second reason for holes in a helmet shell is for access to the air bladder fill points. Most modern football helmets incorporate air filled padding, which have one or more insertion points for a needle to add or release air to conform to the players head.
