An article of apparel may include a base layer and a cover layer. The cover layer may be stitchlessly-secured to an exterior surface of the base layer and positioned to extend along a side area and from a pelvic region to a leg region of the base layer. A width of the cover layer may be greater in the pelvic region than the first leg region. In some configurations, a frictional resistance of the exterior surface of the base layer may be greater than a frictional resistance of a surface of the cover layer.

Swimwear is provided. The swimwear includes: at least one of a waist strap, a back fastener and a drawstring for providing tension at or above an iliac crest of a wearer; a first leg portion including at least a first longitudinal strap or stiffening member, the at least a first longitudinal strap or stiffening member extending from a first hip region of the wearer to a first lateral thigh region of the wearer and being coupled to the means for providing tension; and a second leg portion including at least a second longitudinal strap or stiffening member, the at least a second longitudinal strap or stiffening member extending from a second hip region of the wearer to a second lateral thigh region of the wearer and being coupled to the means for providing tension. The swimwear may be a jammer, a swimskin or a wetsuit.

A hybrid article of apparel is provided. The article comprises a form-fitting inner layer and a looser, more freely-fitting outer layer joined together at various locations to provide an aerodynamic article with improved modesty, among other benefits.

A swimsuit for competition swimming is contemplated as being formed with a network of tension bands disposed interior to the external surface of the swimsuit for storing energy and resisting motion, and with a plurality of reinforcement liners configured to complement the functionality of the network of tension bands while maintaining strength and flexibility in targeted locations while prevent intrusion of water from being retained within the components of the suit through a network of strategically positioned drains. The swimsuit may optimize the swimmer's swimming motion with reduced discomfort and without degrading prematurely due to wear.

A wearable airfoil garment for reducing the cyclist aerodynamic drag. A garment material is elastically tethered between two or more anchor locations on the garment. The anchor locations are positioned and arranged to form transient, self-adaptive, body-conforming airfoil surfaces on the garment. The self-adjustment of the airfoil surfaces preserves the cyclist's comfort as well as the aerodynamic efficiency. The airfoil surfaces change in a body-conforming manner in response to the movements of a person wearing the garment. The aerodynamic performance of the garment is adjustable to the preference of the wearer. Garment airfoils constructed with seams suitably placed to trigger transition of boundary layers.

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 ventilated jacket includes a body portion having a front side and a rear side, a sleeve portion extending from the body portion, and a ventilation system including a plurality of vent openings configured to allow airflow into and out of the jacket. The ventilation system includes an underarm vent having a first end and a second end, the underarm vent extends across a seam between the body portion and the sleeve portion. The jacket further includes a wing that follows a path established by a rear side of the underarm vent. The wing includes a first end adjacent the first end of the underarm vent and a second end adjacent the second end of the underarm vent. The wing extending outward from the underarm vent to channel oncoming air into the underarm vent when the sleeve portion is held in an extended orientation away from the body portion.

The present invention relates to a surface cover for a body which can be brought into contact with a liquid, comprising: a layer which at least partly contains gas and which is designed and arranged such that at least some sections of a layer face facing the liquid contacts the liquid; a gas-permeable layer which is arranged on the gas-containing layer on a face that faces the body and is opposite the face facing the liquid or which is integrally formed with the gas-containing layer; and a gas-supplying device which is connected to the gas-permeable layer such that gas can flow from the gas-supplying device to the gas-containing layer through the gas-permeable layer. The invention also relates to an arrangement and a use.

A suit wearable by a human user includes a torso section, an arm section extending from an upper portion of the torso section, and a leg section extending from a lower portion of the torso section. An exterior surface region of the suit is uneven and has at least one of a different surface friction property and a different surface roughness property in relation to another exterior surface region of the suit.
