Our Retrospec Traverse H1 helmet is the perfect blend of versatility and protection. Our lightweight helmet includes certified ABS exterior and an EPS interior to keep you safe. 10 rectangular vents, 6 on top and 2 located in the front and back, are designed to regulate temperature by generating maximum airflow. Fresh air rushes in and pushes out stuffy, goggle fogging air to keep you cool, dry, and comfortable. This is particularly effective when pairing your Traverse helmet with Traverse goggles. The front of the helmet is designed to accommodate ski goggles and includes a clip on the back to secure them. The inside is lined with a fleece netted cap to wick away moisture and keep you warm. The removable earmuffs are warm, protective, and include a zipper pocket for headphones. This helmet includes an exceptional custom fit made possible by the adjustable dial located on the rear of the helmet. With a simple turn clockwise to tighten, and counter clockwise to loosen, this helmet is designed to fit safely and securely on any rider. The chinstrap is also adjustable and has a super soft cushion to prevent chaffing. These features make the Dirus one of the most safe and comfortable helmets on the market no matter your choice of active sport. Along with the removable earmuffs, you can remove the fleece netted cap, and install foam padding included with the helmet to easily convert from snow/ski to skate/bike to fit your active sports helmet needs all year round.
