Priority Bicycles 174Hudson Stack Helmet - Onyx/Grey
The 174Hudson Stack is a unique folding helmet that offers all the protection of a standard unit but is easier to stow and carry when not in use.
Having passed rigorous testing in both the EU and the United States, the helmet is fully certified. When donned properly, the three tiers of the 174Hudson Stack lock into place. In this configuration, it forms a constant barrier between your head and an impact surface at all angles.
When folded, the 174Hudson Stack helmet is almost 50% smaller than when it is expanded, and at 330 grams, it's also lightweight. The helmet has sleek front air vents and an adjustable chin strap, making it comfortable, and with two sizes, it accommodates a wide range of head dimensions.
