The cheaper versions of these caps are branded as “one size fits all.” In reality, there is a plastic or cloth connector that allows one to resize the cap to the shape of one’s head. So the branding is not 100% accurate as the owner must customize the fit.
“One size fits all” or standardization is something many organizations and people strive for. Simplicity comes with some tangible benefits in terms of costs (e.g. production, storage, training).
For example, when something happens and we open a reception center, family assistance center or similar, we have people complete standardized forms. Problem is no matter how hard we try, we cannot field a form that works for everyone.
Technology might present possible programmable solutions, but do we have several hundred electronic tablets sitting around waiting for an event? Think Emirates’ 615-seat Airbus A380 at 100% load factor or a school with 3,000+ students in attendance.
Somewhere down the road, airports and other venues will likely have deployable kiosks that will use biometrics to prepopulate a form by having people simply walk past them as they enter an assistance facility. But those days are still a ways away.
