An athletic garment assembly for anchoring a rider to a seat of a bicycle includes a pair of shorts that is wearable on a rider's lower body. The pair of shorts has an external engagement that is integrated into a crotch of the shorts. The external engagement engages a nose of a seat on a bicycle when the rider sits on the seat. In this way the external engagement can anchor the rider to the seat.

A lined and padded trouser assembly for cushioning a groin of a wearer includes a pair of pants having a pair of shorts positioned therein and engaged thereto. A waistband of the shorts is substantially aligned with a waistband of the pants. A pad is engaged to and positioned between the pants and the shorts so that the pad is positioned over a groin of a user upon donning the pants. The pad cushions the groin from a vertical pressure applied thereto. The shorts protect skin from chafing and absorb perspiration to prevent skin irritation.

A garment that includes a bottom portion having first and second leg openings, a front part and a back part, first and second shoulder straps that each have a front portion extending upwardly from the front part and a back portion extending upwardly from the back part. The first and second shoulder straps each include a shoulder portion that connects the front portion to the back portion, The back portion of the first shoulder strap includes an upper section and a lower section and the lower section is wider than the upper section. The back portion of the second shoulder strap includes an upper section and a lower section and the lower section is wider than the upper section. At least a portion of the lower section of the first shoulder strap overlaps at least a portion of the lower section of the second shoulder strap.

A system provides ultra-wideband (UWB) positioning. The system exchanges ranging signals at a first rate between a UWB beacon and a UWB tag. The system then determines movement or location information of the UWB tag; and select, based on the movement or location information, a second rate for exchanging subsequent ranging signals between the UWB beacon and the UWB tag. The system then exchanges the subsequent ranging signals at the second rate between the UWB beacon and the UWB tag.

An wearable airfoil garment having one or more stretchable suspension lines disposed on the garment between one or more of the following combinations of proximate locations: the wrist and the shoulder, the back of the ankle and the back of the leg (upper portion of the adductor longus), and along a location on the back of the arm and a location on the torso. For each stretchable suspension line, a flexible and stretchable cloth material is attached to and forming a portion of the garment. The flexible and stretchable cloth material is attached to the stretchable suspension line, forming a draped and collapsible airfoil. The one or more stretchable suspension lines forms a cusp shape, whereby a trailing edge is formed.

A wearable arm airfoil garment for reducing the cyclist aerodynamic drag. The wearable arm airfoil includes a front bluff elastic band having ends connected at two anchors, with a first anchor located proximate to the wrist, and a second anchor located proximate to the shoulder. The front bluff elastic band stretches along the radius bone and the humerus bone, between the two anchors. The airfoil also is a stretchable garment material, the garment material wrapping around the arm and over the band from wrist to shoulder, with a body conformable stretchable bodice. In one example, the arm airfoil includes a shirt torso airfoil.

A low drag garment is made from a fabric having a textured region with a texture height H, wherein the texture height H increases substantially continuously with the surface angle θ in said textured region. Optionally, the substantially continuous increase in texture height H comprises a plurality of incremental increases in texture height, and wherein each incremental increase in texture height is less than 200 μm.
