Apparatus and associated methods relate to a retaining module coupled to headwear to selectively increase friction between the headwear and a user's head. In an illustrative example, the retaining module includes a coupling region coupled to an inner surface of the headwear. The retaining module may, for example, include an engaging region extending from the coupling region and including a retaining surface. The retaining module may be configured, for example, such that the engaging region is selectively operable between a stowed mode in which the retaining surface is substantially separated from the wearer's head by a portion of the headwear, and a deployed mode in which the retaining surface engages the wearer's head such that a coefficient of friction between the head and the headwear is increased relative to the stowed mode. Various embodiments may advantageously provide selectable levels of resistance to removal of the headwear.

An apparatus includes a first portion and a second portion. The first portion generally comprises a channel feature. The second portion generally comprises a rib feature. The rib feature is generally configured to fit within the channel feature.

Ear compression apparatus including an ear compression band having a substantially circular shape. The ear compression band can have a circumferential length and a compression band operably coupled with at least one-half (½) of the circumferential length of the ear compression band. The compression band can be coupled with less than nineteen-twentieths ( 19/20) of the circumferential length of the ear compression band, thereby forming a front portion of the circumferential length not having a compression band coupled therewith.

A hat includes a first and second overlapping panel in the rear of the body and an elastic band. The overlapping panels each comprise an arcuate edge. When overlapped, the arcuate edges define an aperture. An elastic band attaches to the arcuate edges and transitions from the first arcuate edge to the second arcuate edge in a looping manner. When a wearer pulls her hair through the aperture, the aperture increases in size. Once the wearer's hair is pulled through the aperture, the aperture decreases in size and provides a secure fit around the wearer's hair. The elastic loop supports the long hair upwards in a manner that prevents the hat from riding up or the hair from falling onto a rear brim.

A mechanism to adjust the size of headwear is provided. Two engagement clips attach to either side of an open space on the headwear. A tooth/track connects the two clips. The clips may be adjusted to fit the size of the head.
