Just1 produces it in two distinct geometries so that a size XS shell is proportionally correct for a 53–54 cm head rather than merely a scaled-down version of a larger mould. The EPS liner follows the same logic with its own two-size architecture, meaning the energy-absorbing foam sits at the right thickness and density regardless of which size you select. The result is consistent impact protection across the full XS-to-XXL range — a detail that matters and one that separates thoughtfully engineered helmets from budget alternatives.\u003c\/p\u003e\u003ch2\u003eEveryday Comfort and Hygiene\u003c\/h2\u003e\u003cp\u003eThe Protx2™ interior treatment addresses one of the most persistent practical problems with regular helmet use: hygiene. The antibacterial and odour-inhibiting properties keep the lining fresher for longer between washes, while the fast-drying construction means the helmet is ready to ride again quickly after cleaning. All interior pads detach fully for machine washing, and the fit is designed to be snug and stable without creating pressure points on longer commutes or touring days. Ventilation channels promote air circulation to keep the interior temperature manageable across seasons.\u003c\/p\u003e\u003ch2\u003eEquipment and Practical Details\u003c\/h2\u003e\u003cp\u003eThe J-STR comes with a nose cover included and ships in a helmet bag to protect the gloss finish during storage and transport. The scratch-resistant visor offers a wide field of view and is prepared for compatible accessory visors from the Just1 range, giving you the option to add a tinted or photochromic lens without replacing the helmet. The gloss white colourway is one of the most visible finishes available on road, an advantage that counts in low-light urban environments and on open roads alike.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThe Just1 J-STR is an adult full-face helmet available in sizes XS through XXL.
