Arai GP-5W Racing Helmets
The Arai GP-5W comes without a visor, but with the adjustable Hyper-T' peak and removable cheekpads. This helmet is the result of the demand from driver in the touring car classes, where the added protection of a visor is not necessary. The GP5W offers a large aperture and extensive ventilation with two IC Ducts 2 at the front with the proven Delta Duct in the back. Anchor points for the HANS system are already present.
The GP-5w is largely based on its big brother the GP-5 (PED), while taking some clues from the GP-5k model. The eyeport of the GP-5w has been enlarged to 90mm (approx. 3.5") as compared to 72mm (approx. 2.75") and should be heavily favored by sedan or rally drivers, while some open wheeled drivers have also expressed interest in a larger eyeport from Arai.
 Construction
Constructed of Arai's exclusive clc (Complex Laminate Construction) shell technology, which helps offset the added weight of a larger shield. The result is that the GP-5w maintains a low overall weight. The exterior and interior shape and design are nearly identical to those found on the GP-5 (PED) but due to the larger eye port opening, uses a new and exclusive shield. However the shield hardware and tear-offs are the same as used with the GP-5 and GP-5K.
Cleaning
Removable, washable and replaceable cheek pads allow more frequent and thorough cleaning and/or replacement for a more personalized fit for those with a narrower are broader facial structure than anticipated with the stock pad dimensions.
HANS
Already pre-drilled for installation of HANS device. There is also a special seat for the HANS posts molded into the shell.
Interior
The interior fit is typical Arai, benefiting from years of research and refinement, resulting in a helmet that more closely matches the shape of the human head. Such a close fit allows for the smallest possible helmet to be worn, while still being comfortable. Often times a poor fitting helmet results in the use of a helmet that is a full size too large in an effort to avoid painful pressure points.
Fit
Combined with its legendary comfort and fit, Arai concentrates on balance and a lower center of gravity. Al too often people concentrate on the weight of a helmet instead of how that weight is distributed over the entire helmet, how much of that weight is carried down low, and most importantly, how that weight is carry on your head - up on top of the helmet where it is more susceptible to buffeting and where it can put more stress and discomfort near the shoulders. (A properly fitted helmet will distribute the weight more evenly over and around your head, actually making the helmet seem light. A helmet that is more evenly balance and carries more of its own weight down low will also appear to be lighter and cause less fatigue.)
