The Brentwood 2.0 is 15% lighter and 20% better ventilated than its predecessor. Universally applicable thanks to its optimal fit, advanced ventilation, comfortable chin strap, and lightweight design, this helmet provides the safety that athletes expect. Brentwood bike helmets also look great for everyday use. Crowned as a top helmet by many bike couriers and tested in action, Bern Brentwoods continue their unstoppable rise as a city helmet. Additionally, Bern Brentwood helmets are highly flexible due to their interchangeable inner lining. In summer, they offer glare protection and maximum ventilation, while in winter, they feature a cozy and warm lining made of faux fur or cotton knit. The Brentwood helmets are also very lightweight and compact, thanks to the rigid foam that is permanently molded to the outer shell. The infinitely adjustable strap guides are easy to secure, allowing for quick and optimal adjustment at the ear to prevent slipping. Once set, everything stays perfectly in place.
