There are numerous problems with the above mentioned single drawstring adjustment hood
system, primarily being that the hood has a substantially rigid attachment to the jacket about a
long axis that goes through the user's head, neck,
torso, and legs, such that when the user turns their head from side to side, the hood keeps the face opening periphery in a single orientation facing forward thus causing the user to lose their
peripheral vision quickly as their head turns within the substantially rigid
hood assembly, that is caused from the hood having a loose fit to an outer surface of the user's head with the face opening periphery being reduced in size or area resulting in limiting the user's access through the hood to the external environment to be facing forward only, thus being very inconvenient for the user in sporting activities wherein the user turns their head side to side quite frequently.
A way to help alleviate this problem is to leave the drawstring in a loose state, thus resulting in a larger face opening periphery to expand the ability of the user to have increased
peripheral vision when turning their head side to side, however, doing this causes another problem in that the hood has opening gaps around the user face periphery that can destroy the function of the hood to help keep the user's head warm, in allowing inside of the hood cold wind,
snow, sleet, or rain to enter the hood through the opening gaps around the user's face periphery, this issue is especially acute when the user is moving forward through the external environment when running, bicycling, and the like.
So basically the typical jacket hood is really only useable when the user is only facing forward and not turning their head side to side, being usually not the case.
Of course an alternative could be for the user to use a
stocking cap for head warmth that does not have the problem of the loss of user
peripheral vision when the user turns their head side to side as the
stocking cap is not attached to the jacket and rotates with the head, however, this brings on another problem in that the
stocking cap fails to provide warmth or shelter for the user's neck, being a problem in cold wet weather, further if the user in engaged in high head movement activities, the stocking cap will not stay attached to the head well, unless of course a
chin strap is used with the stocking cap, however, still having the aforementioned problem of the user's neck being exposed to wet and
cold weather.
Thus in Little, it is recognized that the loss of user peripheral side vision is made worse by the typical fairly rigid attachment of the hood to the jacket, however, as FIG. 1 shows, the hood has a very loose fit to the user's head outer surface, wherein the user's head in turning side to side about the
long axis would still allow the user's head to rotate within the hood interior, thus resulting in the user losing the side
peripheral vision, as being the previously identified problem with conventional hood design and structure.
Although Little claims that the hood will rotate about the
long axis with the user's head rotating the same way, there is no teaching of how the hood affixes to the user's head outer surface to accomplish this.
