Description
The Switchblade™ Mips® is an ASTM Downhill certified full-face helmet with a removable chin bar so you can easily switch to rowdy when it's time to descend.
Everything about the Switchblade is optimized for the descent. That's why in addition to mandatory standards it's also certified to ASTM-1952 DH with and without the chinbar.
The chinbar is easy to remove - just push the buttons under the chinbar, rotate up, and take off - and it's just as easy to reinstall. Another boast-worthy feature on the Switchblade Mips® is the Roc Loc Air DH fit system, which has a bumper around the dial to prevent accidental adjustments if your helmet contacts your backpack or neck brace - all while keeping you cool. When the chinbar comes off, Wind Tunnel cheek pad ventilation adds even more cooling power as you start to climb. Plus, the full-cut style gives this helmet an aggressive look and provides ASTM certified coverage even when the chinbar is removed. When your ride is all about descending, your helmet should be too, and the Switchblade Mips is the only removable chinbar helmet that is truly built for the down.

Note: We recommend you try helmets on before buying. Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.
HOW TO ADJUST THE FIT
Step 1: If the helmet has one, adjust the fit system at the rear of the helmet for a snug, secure fit. Some fit systems also include a vertical tuning feature that allows you to adjust the fore/aft tilt, for optimal positioning on your head.
Step 2: Adjust the straps so that they sit just below the earlobes.
Step 3: Adjust the buckle so that it rests against the back of the jaw/throat.
Step 4: Adjust the interior pads if needed.
Step 5: Check the fit to make sure helmet is comfortable and secure. It should not roll forward or back, or be able to slide off.

Giro Switchblade
Website purchase was easy, delivery was quick and the fit is very good and matches the sizing chart. This is my first full face (convertible) and I might just stick to the full face - hot days and hillclimbs might change that.
