TSG Evolution Skateboard Helmet | CPSC Certified with EPS Impact Foam | Hard Shell Action Sports Head Protection with Customized Fit SUPREME PROTECTION  TSGs custom injected molded ABS design creates a helmet that can absorb a large amount of impacts. This creates a tough outer shell, to help prevent any cracks or splits, which would otherwise compromise the helmet. Combined with EPS hard foam and Soft Foam density pads, the Evolution surpasses the CPSC standard. PERFECT FIT  Each size of the TSG Evolution comes with different density pads, to ensure the helmet fits snugly on the user. A loose-fitting helmet causes more danger than protection, and having the finely tuned fit provided with the density pads only increases the safety this helmet can provide. COMFORTABLE  TSG knows that comfort is just as important as protection. If the helmet isnt comfortable, you are less likely to wear it. With the included density pads, and low-cut design, the Evolution is a great all-around helmet. With its lightweight construction, youll barely notice it on your head, until it saves you from an impact! VENTILATION  The TSG Evolution has 14 air vents, to maximize airflow, keeping you cool during the summer. The vents are designed to allow cool air to flow in, while pushing hot air out, leaving you with a cool, comfortable helmet that you can wear for longer periods of time. USER DESIGNED  TSG has a long history of producing top quality protective gear, designed by their sponsored riders. You can rest assured that all TSG products have been heavily researched and developed prior to release, and undergone extensive stress testing prior to receiving certification.
