A helmet spreads and absorbs impact, limits brain-jarring rotation, and shields bone, skin, and eyes so crashes are more survivable.

Injected sunglasses are frames made by injecting molten thermoplastic into a mold to create light, durable shapes with consistent fit.

MIPS in helmets means Multi-Directional Impact Protection System, a slip layer that helps reduce rotational forces from angled hits.

A premium cigar tastes like layered smoke with sweet, nutty, woody, and spicy notes that shift from mild to bold as the leaf warms and the ash grows.

MIPS in ski helmets means Multi-directional Impact Protection System, a low-friction layer that helps reduce rotational motion in angled crashes.

On smart watches, “mm” means millimeters, usually the case size or the band lug width that determines fit and compatibility.
