Functional and Stylish

I've put it through the wringer

This helmet offers all the safety features you want in a sleek and stylish design. The MIPS liner adds additional protection against rotational forces and the 3-way fit adjustment enables you to dial in the perfect fit. This is one of the more comfortable helmets I have ridden in. It also has plenty of vent holes to ensure you're not overheating when on a long, hot climb. For the money I think this is one of the best helmets on the market. It's just a bonus that it looks great!
