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 offers the safety that athletes expect. Brentwood bicycle helmets also look great for everyday use. Crowned as a top helmet by many bike couriers and tested in the field, Bern Brentwoods continue their unstoppable success as urban helmets. Additionally, Bern Brentwood helmets are highly flexible due to their interchangeable inner lining. In summer, they provide glare protection and maximum ventilation, while in winter, they come with a cozy and warm lining made of faux fur or cotton knit. The Brentwood helmets are also very lightweight and, due to the rigid foam that is permanently bonded to the outer shell, very compact. 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.
