The Troy Lee Designs A1 MIPS Helmet offers unrivalled all-mountain protection – utilising industry-leading safety standards so you can ride the trails without compromise. Developed and refined explicitly to provide the very best impact protection, the A1 MIPS Helmet means that you’re always ready to enjoy the trails. An innovative Multiple-Impact Protection System and EPS liner give outstanding protection against angled impacts. If you’re looking for the ultimate, fully-optimised trail helmet then look no further. The Multiple Impact Protection System utilised in the A1 MIPS is an industry-leading and rigorously tested protection system that is the result of a dedicated mission to reduce strain on the brain in angled impacts. The technology employed in MIPS enables rotation of the head relative to the helmet structure upon impact, demonstrably reducing the detrimental effects of impact to the head. If you value maximal safety, then MIPS is the way to go. The A1 MIPS is constructed from a reinforced polycarbonate shell, integrated with an expanding polystyrene liner which is the result of a singular drive for safety on impact. An innovative design ensures that it remains lightweight and ventilated with a 16-port airflow system which enables air to be drawn across the head, keeping you cool on the trails. Fully-adjustable cam-lock strap dividers mean that you can contour the helmet to fit your own head and maximise comfort and protection on every ride. With a three-year warranty on all TLD helmets and a variety of striking colourways you can be confident that you’re investing in an industry-leading lid.
