Maximum coverage, open face mountain bike helmet
The Dropframe Pro Flow Helmet is a game-changing, open-face 3/4 enduro helmet. It features Mips®, the BOA® Fit System for class-leading fit and security, increased ventilation, plus an Ionic+® liner and cheek pads to optimize fit. With its increased coverage for the ears, jaw, and back of the head, this MTB helmet provides the most complete coverage we offer in an open-face helmet.
- Mips® added protection system has been proven to reduce the rotational motion when implemented in a helmet by absorbing and redirecting energies and forces otherwise transmitted to the brain
- Dual-density Varizorb™ EPS provides improved protection by spreading forces of impact across a wider area
- 8 Big Bore vents and 7 exhaust vents keep you cool and aid in moisture management
- The securely fixed visor is positioned to channel airflow into the Big Bore vents
- Removable antimicrobial and moisture-wicking liner
- Includes additional pads for custom dialed fit
Size
- Sizes: small, medium, and large (see size guide for measurements)
How to Dial Your Fit
- BOA® dial: micro adjustments - counterclockwise to loosen, clockwise to tighten - allows for a precisely dialed fit. Adjust while wearing the helmet.
- Back cradle: four points of adjustment move the cradle up or down your head to ensure the best fit possible.
- Comes with additional cheek pads and liners for a personalized fit
- Select thinner or thicker pads to achieve a tighter or looser fit according to your preferences
