With a lightweight ABS shell construction and passive ventilation, the Bollé junior helmet offers the best in comfort, performance, and safety. Added to this year's helmet collection at Costco is an added level of protection with MIPS® technology (Multi-directional Impact Protection System). All Bollé junior helmets feature removable ear pads, a washable and removable premium lining, and a goggle strap retention system to keep goggles securely in place. MIPS® MIPS is a patented solution for multi-directional impact protection. With its innovative technology, the helmet can slide relative to the head, enhancing protection against rotational motion of the brain caused by angled impacts. Injected ABS The injected ABS shell provides durability and strength, while the EPS core ensures high-volume impact absorption. Click-To-Fit® System The new Click-To-Fit® system allows for easy and quick fine-tuning of the helmet's fit. The rubber adjustment wheel makes it easy to tighten or loosen the helmet, even with gloves on.
