The Troy Lee Designs A2 Decoy MIPS helmet is a trailblazing all-mountain bike helmet. The tried and tested design of the TLD A1 MIPS Helmet has now been over-engineered to increase ventilation without sacrificing class-leading protection or its lightweight design. This is a helmet that performs without cramping your style! Featuring the next-gen MIPS liner, the A2 Decoy MIPS Helmet offers increased protection upon impact, especially against rotational forces. If you weren't sure about how safe the TLD A2 Decoy MIPS Helmet really was, it still retains Virginia Tech's perfect 5-star rating! The TLD A2 Decoy MIPS Helmet improves on the A1 MIPS Helmet, by increasing airflow by an insane 25%! This is all thanks to a redesigned ventilation system with larger vent ports and a more efficient air channel system. Taking advantage of pressure differentials to create a vacuum, the A2 Decoy MIPS helmet draws air in before expelling it. Ultimately, this results in heat being drawn away from your head so you can go all day while keeping your cool. The Troy Lee Designs A2 Decoy MIPS helmet prioritises comfort without sacificing on safety. With the increased ventilation, it's surprising that TLD were able to increase the frontal protection of the A2 Decoy. However, that's just what they've done! It features TLD's patent-pending EPP in the frontal section to really ensure your noggin is protected no matter what. If you've never heard of EPP before, that's because it's an all-new innovation from TLD! It's the first dual-density EPS impact liner, and increases protection by 16%!
