Bontrager Solstice Helmet
The Bontrager Solstice Helmet gives you essential protection without breaking the bank. We designed this helmet for commuters, recreational cyclists, and anyone who values safety and comfort on every ride.
Our in-molded polycarbonate shell absorbs impact energy while keeping the weight low, so you’ll barely notice it’s there. Fourteen strategically placed vents work with internal channeling to keep air flowing across your head, preventing overheating on warm days or challenging climbs.
The adjustable fit system lets you dial in a secure, personalized fit in seconds, and our headlock reinforcement provides stability without pressure points. Reflective accents on the rear increase your visibility to drivers during low-light conditions, adding an extra layer of safety to your daily commute or weekend adventure.
Built for Safety & Comfort
Protection Technology & Safety Standards
The Bontrager Solstice Helmet meets rigorous U.S. CPSC and European CE safety certifications, ensuring you’re protected by internationally recognized standards. Our in-molded construction fuses the outer polycarbonate shell directly to the impact-absorbing EPS foam liner, creating a unified structure that distributes impact forces more effectively than traditional helmets.
This manufacturing process also eliminates unnecessary weight while maintaining structural integrity. The helmet’s coverage extends low around the temples and back of the head, providing protection in the zones most vulnerable during side-impact scenarios.
Ventilation & Comfort Features
Fourteen vents positioned across the crown and brow work together to create consistent airflow from front to back. Internal channeling guides cool air over your scalp while pushing hot air out through rear exhaust ports, maintaining a comfortable temperature even during sustained efforts.
The vent design balances airflow with structural strength, so you get cooling without compromising protection. Soft padding along the brow and temple contact points wicks moisture away from your skin, preventing sweat from dripping into your eyes during intense rides.
Fit System & Sizing
Universal Fit Range
The adjustable dial system at the rear of the helmet accommodates head circumferences from 54 to 61 centimeters, covering the majority of adult riders. Turn the dial clockwise to tighten or counterclockwise to loosen, finding your ideal fit in seconds without removing the helmet.
Measure your head circumference by wrapping a flexible tape measure around your head approximately one inch above your eyebrows. If you fall between sizes or prefer a looser fit, we recommend sizing up.

Bontrager Solstice Helmet Questions
The Bontrager Solstice Helmet features a universal fit system that adjusts to fit head circumferences from 54 to 61 centimeters. Measure around your head about one inch above your eyebrows with a flexible tape measure to determine your size.
If your measurement falls at the upper or lower end of the range, test the fit by adjusting the rear dial to its tightest or loosest setting before riding. The helmet should sit level on your head without tilting forward or backward.
Yes, the Solstice complies with both U.S. CPSC and European CE safety certifications. We test every helmet design beyond the minimum requirements for these standards, subjecting them to multiple impact scenarios and retention system strength evaluations.
The in-molded construction creates a unified shell-and-liner structure that distributes impact forces effectively. We recommend replacing your helmet after any crash, even if no visible damage appears, since internal foam compression may reduce future protection.
The Bontrager Solstice Helmet works well for casual trail riding and cross-country routes. For aggressive downhill riding or technical terrain with higher fall risks, we recommend our Blaze WaveCel mountain bike helmet, which features extended rear coverage and enhanced rotational impact protection.
The Solstice provides certified impact protection for recreational off-road use, but the vent design and coverage profile are optimized for road cycling and commuting. Consider your typical riding style and terrain when selecting the right helmet.
Clean the outer shell with mild soap and water using a soft cloth, avoiding harsh chemicals or abrasive cleaners that can damage the polycarbonate material. The internal padding pops out for hand-washing with gentle detergent.
Allow padding to air dry completely before reinstalling—never use a dryer or direct heat source. Wipe down the adjustment dial and straps periodically to remove salt, sweat, and dirt buildup. Store your helmet away from direct sunlight and extreme temperatures to preserve material integrity.
Yes, the included visor snaps into integrated mounting points and can be removed in seconds without tools. Some riders prefer the visor for sun protection and light rain shielding, while others remove it for a more streamlined profile on fast road rides.
The mounting points remain flush with the helmet shell when the visor is removed, so there are no protruding clips or rough edges. You can switch between configurations based on weather conditions or riding style.
The Solstice uses traditional in-molded EPS foam construction that meets all required safety standards at an accessible price point. Our WaveCel helmets add a collapsible cellular structure designed to absorb rotational forces during angled impacts, providing an additional layer of protection.
Both helmet types pass the same CPSC and CE certifications, but WaveCel technology addresses specific impact scenarios differently than standard foam. The Solstice delivers reliable, certified protection for riders who want proven safety without premium features.
Yes, the Bontrager Solstice Helmet accommodates eyewear comfortably. The front vents and brow padding are positioned to avoid interference with glasses temples, and the rear adjustment system sits low enough that it won’t push glasses forward.
Many riders wear both prescription glasses and sunglasses with this helmet without issues. If you wear particularly wide or thick-framed glasses, adjust the side straps to form a Y-shape slightly behind your ears for optimal clearance.
