A lower-body garment comprises a left leg portion, a right leg portion and an intermediate portion connecting the left leg portion to the right leg portion. The intermediate portion has a groin covering portion adapted to extend over a groin area of a wearer. The groin covering portion has a 3D textile. The 3D textile has at least one opening. In use, the opening of the 3D textile is stretched and compressed by a walking movement of the wearer thereby creating air movement.

A garment or article of clothing made of a resilient/elastomeric material includes at least a waist portion, a first leg portion, and a second leg portion. The waist portion further includes a pocket on the rear of the garment, where the pocket is defined by a backing panel, a first flap, and a second flap. The first flap is at least partially disposed over the second flap to secure contents between the backing panel and the second panel, and thus, within the pocket. When the waist portion is stretched, the tensile forces imparted onto the waist portion by the resilient/elastomeric material causes the first flap to at least partially overlie the second flap. The pocket is sized and shaped to receive smartphones and other small personal items, such as keys, money, credit cards, identifications, etc.

A lower-body garment comprises a left leg portion, a right leg portion, an intermediate portion connecting the left leg portion to the right leg portion and two separators. The intermediate portion has a middle portion and a groin covering portion adapted to extend over a groin area of a wearer. The middle portion connects the left groin portion to the right groin portion. Each one of the two separators extends from a respective one of the left groin portion and the right groin portion of the groin covering portion so as to reach between a scrotum and the respective left leg and right leg of the wearer. Each one of the two separators has a 3D textile with an opening. In use, the opening of the 3D textile is stretched and compressed by a walking movement of the wearer, thereby creating air movement.
