Before You Select a Size: Helmet-Fit Facts
A helmet is one of the most important pieces of riding gear you will choose, and the size printed on the label is only a starting point. Head circumference, head shape, crown contact, cheek-pad pressure and the retention system all affect whether a helmet fits correctly. Two helmets marked the same size can fit very differently—even within the same brand.
Measure around the widest part of your head, keeping the tape level and approximately one inch above your eyebrows.
A new helmet should feel evenly snug around the entire head without sharp or painful pressure points.
When you move the helmet gently from side to side, your skin should move with the liner rather than the helmet sliding independently.
Fasten the retention system and confirm that the helmet cannot roll forward or lift off the head.
Wear the helmet for several minutes before deciding. Comfort padding may settle with use, but an incorrect shell shape or painful pressure point is unlikely to be solved by choosing blindly.
Why Come to Eagle Leather for a Helmet Fitting?
Our staff is trained to help with helmet fitting and can help you compare head shape, size, pressure points and retention across different models. Inventory changes daily, but Eagle Leather consistently carries many hundreds of helmets—often approaching 1,000 units—across half-shell, open-face, modular, adventure and full-face styles. That selection gives you the opportunity to compare brands and internal shapes instead of relying on a size label alone.
For such an important piece of riding gear, we encourage you to visit Eagle Leather for an in-person fitting before selecting a size without trying the helmet on.

The Shoei J Cruise 3 is a premium open face touring helmet designed to give riders an expansive field of view, excellent airflow, refined aerodynamics, and the convenience of a built in sun visor. It is especially well suited to touring, commuting, scooter riding, and warm weather travel where open face freedom and serious engineering both matter.
Purpose built open face shell
The Advanced Integrated Matrix shell combines fiberglass and organic fibers to create a strong structure with controlled elasticity. Shoei shapes the shell in multiple sizes to reduce unnecessary bulk across the size range. A multi density EPS liner manages impact energy while also providing channels for ventilation.
Wind tunnel developed aerodynamics
Shoei used extensive wind tunnel testing to control lift, drag, and turbulence around the open face design. The integrated rear spoiler and smooth shell contours help keep the helmet stable in the moving air created by upright and touring motorcycles.
Major ventilation improvement
The redesigned upper ventilation system delivers substantially more airflow than the previous J Cruise generation. Shoei reports up to 70 percent greater ventilation performance. Multiple intake ports feed EPS channels that move cooling air over the head, while rear exhaust ports release warm, humid air.
CJ 2 shield system
Wide, tall shield provides generous coverage and peripheral vision
Optically accurate curvature helps minimize visual distortion
Secure sealing and locking design helps control wind and weather
Tool free shield removal simplifies cleaning and replacement
Pinlock ready for compatible anti fog protection
QSV 2 internal sun visor
The enlarged internal sun visor provides about 5 millimeters more coverage than the earlier design and meets the demanding optical requirements of the EN1836 standard. An external slider makes it easy to deploy or retract with a gloved hand. The sun visor stores inside a dedicated space so protective EPS thickness is maintained.
Premium interior and fit tuning
The fully removable and washable interior uses moisture managing fabric and a three dimensional shape for secure support. Shoei’s top pocket system allows additional fit adjustment at the crown. Replaceable cheek pads and center pads make it possible to refresh or fine tune the fit over time.
Communication ready
The Shoei Comlink interface is designed for clean integration with the optional Sena SRL3 communication system. Speakers, microphone, battery, and controls can be positioned with minimal external bulk.

For the best protection and comfort, choose a size that fits evenly snug around the entire head with no isolated pressure points.
An open face helmet, also called a three quarter, covers the top, sides, and back of the head and leaves the face and chin exposed. You get better airflow, an unobstructed view, and the ability to talk or drink without removing anything. What you give up is chin and face coverage, and open face helmets are noticeably louder at highway speed than an enclosed helmet.
Frequently Asked Questions About Open Face Helmets
What does an open face helmet actually protect?
An open face helmet, also called a three quarter, covers the top, sides, and back of the head and leaves the face and chin exposed. That is the whole trade. You get better airflow, an unobstructed field of view, and the ability to talk, drink, or put on glasses without removing anything. What you give up is chin and face coverage, which a full face or a closed modular provides. Riders who choose open face usually do so for around-town riding, warm weather, or the feel of it, and accept the exposure knowingly rather than by accident.
Do I need goggles or a visor with an open face helmet?
In Washington, yes, unless your motorcycle has a windshield. State law requires glasses, goggles, or a face shield when riding without one, and an open face helmet does not satisfy that on its own unless it has a shield fitted. Some open face helmets come with a flip-down shield, some accept one as an accessory, and some are built for use with goggles. Washington also restricts tinted eye protection, which cannot be used from a half hour after sunset to a half hour before sunrise or any time visibility drops below 500 feet, so a clear shield or clear goggles is the reliable default here. Rules vary by state, so check where you ride.
Can I wear an open face helmet in the rain?
You can, but rain hits your face directly, and at 50 mph that stings. A flip-down shield helps a great deal and is the difference between tolerable and miserable in Pacific Northwest weather. Cold is the other factor, since wind chill on an exposed face at 40 degrees is genuinely uncomfortable within a few miles, and a neck gaiter or balaclava only covers part of it. If you ride year round here, most riders end up with an open face for summer and something enclosed for the wet months. If you only want one helmet for Washington riding, a full face or modular is the more practical choice.
Are open face helmets loud?
Louder than a full face, yes. A full face seals around your head and routes air over a closed shell, while an open face leaves your face and the underside of the helmet exposed to turbulent air. The difference grows with speed and is most noticeable above about 50 mph. Earplugs are the practical answer and are worth wearing under any helmet on the highway, since sustained wind noise causes hearing damage over years rather than in one ride. A windshield on the bike also cuts open face noise considerably.
Will a communication system fit an open face helmet?
Usually, though open face helmets have less room than a full face and fewer places to put the clamp. Speakers go in the ear pockets if the liner has them, and the microphone is the harder part, since there is no chin bar to mount a boom to. A boom mic on a short arm generally works better than a wired mic on an open face. Expect more wind noise on the microphone than a rider in a full face would get, which matters more for intercom than for music. Bring your helmet to our Lakewood store and we will check the fit against the systems we carry, and if you buy the system from us we will install it at no additional charge.
Are open face helmets DOT rated?
Yes. An open face helmet can be certified to the same federal standard as a full face, and a DOT-certified open face is legal for road use in Washington. Less coverage does not mean uncertified. What is not legal is a novelty helmet, meaning a shell sold without DOT certification, and those are common in the half and open face shapes because they look similar to the real thing. We do not stock novelty helmets. Certifications are listed on each product page, and the certification sticker is on the helmet itself.
