Description

Thermo-injected polymer shell with variable thickness delivers exceptional impact protection while keeping the helmet lightweight at just 1430 g (ECE) and 1460 g (DOT).

Ten intake vents and seven exhaust ports maximize airflow for superior heat transfer and all-day riding comfort.

Patented low-friction liner coating reduces rotational forces on oblique impacts by mimicking the brain’s natural cerebrospinal fluid slip plane.

Innovative visor release system deploys under predetermined force to reduce neck loads during an impact.

Removable cheek pads, integrated hydration tube channels, and recycled comfort liner offer a customizable fit and eco-conscious performance in a DOT- and ECE 22.06-certified design. Meets Federal Motor Vehicle Safety Standard 218 (FMVSS 218).

Engineered for MX, Enduro, and off-road riding, the SM3 Helmet integrates advanced technologies and innovations designed to enhance ease of use, comfort, and impact protection.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $35 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Alpinestars products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
