Bontrager Boa Recreational Cycling Helmets

Types of Bike Helmets 

• Recreational: An economical choice with impact protection for casual riding 

• Mountain bike: Extra rear head coverage for off-road and rugged trails with ventilation options 

• Road bike: Lightweight, aerodynamic and highly ventilated 

Fit Tips 

• Measure your head’s circumference by wrapping a flexible measuring tape around the largest portion of your head (or use a piece of string, then measure its length). 

• Check brand sizing charts for your head circumference. 

• Aim for a snug fit but not too tight. If between sizes, go with the smaller size. 

Added Protection 

Look for technologies that reduce rotational forces during a crash, like Mips, WaveCel or KinetiCore. 

Features 

• Vents: More vents improve airflow and reduce weight.

• Visor/brim: Keeps the sun out of your eyes; common on mountain bike helmets. 

• Chin bars: Extra protection for downhill mountain biking or racing.
