Specialized's Duet helmet is loaded with features. The Headset SX fit system and Tri-Fix strap make it a breeze to dial in your perfect fit, while the 4th Dimension cooling system has large vents so you can stay cool and dry. Reflective accents on the webbing and helmet shell increase your visibility, and the Duet includes a detachable visor.
Specialized's Tri-Fix webbing system lets you get the perfect helmet fit quickly and easily. Using a wide, fixed ear-loop strap, it reduces redundant webbing for less weight, creates a clean look, and makes fitting the helmet a breeze.
