Wife got it for me as a gift, but it doesn't fit, probably going to move to the XXL 7idp helmet, as that's the largest full faced I can find. Anyway, my loss is your gain! ______ From their website: Drop in to steep, loose lines with confidence knowing you're fully protected with the 100% Aircraft-Composite Helmet. Modeled after their flagship Aircraft Carbon, this helmet is precision engineered with a strong and lightweight fiberglass composite shell molded to shock-absorbing EPS impact foam, resulting in a helmet that offers first-rate protection at a considerably lower cost. Within that shell, 100% also carefully carved out a staggering 25 vents and air channels, which is no small feat in a full face helmet. This well-executed system establishes a consistent flow of air into and out of the shell so that you stay cool and dry on the hottest mid-summer days without compromising the structural integrity of the helmet. 100% also added useful details like breakaway cheek pads, an integrated compartment that eases compatibility with emergency release systems, and compatibility with neck braces, all features that put it on the same playing field as other high-end DH helmets. Of course, 100%'s emphasis on sleekness and low weight set it apart from cushier options, but if those two features are important to you, the Aircraft is a strong contender. 100% does include a soft, washable liner as well as an adjustable visor that attaches via durable aluminum screws. The helmet secures with a trusty steel D-Ring buckle system that you can count on for season after season. Lightweight Design: Featuring a Fiberglass Composite shell. Active Cooling System: Maximizes airflow with a staggering 25 ventilation ports. Antimicrobial, washable and replaceable comfort liner, cheek pads and chin strap cover Emergency Release Cheek Pads: For quick, safe removal. Integrated Compartment: Accepts inflatable emergency release systems. Compatible: With most popular neck brace systems. Steel D-Ring buckle: Provides a secure fit while limiting weight. Perfect Fit: Engineered with 2 Shell sizes and 3 EPS Sizes and 4 Cheek pad options Adjustable Visor: With machined lightweight aluminum screws. 25 enhanced venting channels create the Active Cooling System; specifically designed to manage airflow and ventilate the entire helmet.
