Safety First

Waking up late for work is never fun, and having to weave through traffic, pedaling full speed on your bike can even make it a bit dangerous. You're not worried though, you've got the Smith Portal MIPS Bike Helmet on, the protection you need just in case you hit a pothole on your way to the office. While you might have to worry about showing up to the office and needing a change of clothes, the 18 built-in vents and Smith's AirEvac system will ensure that your head stays plenty cool, so at least your hair will look good. The in-mold design is remarkably lightweight while providing solid impact protection, and Smith even added an additional MIPS layer to reduce rotational impact forces in case you crash.
