The closest matches are the fit adjustments and size figures below. Banwood Eco Helmet: The Australian maker page lists weight as 355 g (the UK maker page says 280 g and the store says 0.78 lbs; the sources disagree), and mentions dial-fit, recycled chinstrap and ventilation. The helmet height can be adjusted in three steps. The Australian maker page says ages 3+, head circumference 50–54 cm, and Australian/New Zealand Standards certified; the UK maker page gives ages 2–7 and 52–56 cm, so the age and size figures disagree. Doona Liki Helmet: The helmet has a dial-fit adjustment system for a customized and secure fit. The maker says the helmet is for learning to ride the Liki Trike and for the next size of bicycle until age 4. Banwood Classic Helmet: The helmet height is adjustable in three steps.
