The Rounderbum Essentials Jockstrap is a men's jockstrap with a full front pouch, a wide waistband and an open back. Rounderbum makes its Essentials range in two fabrics, and this listing carries colours from both. Black, yellow, green, purple, red, blue, navy, gray, Naranja, Blue 7 and Blue 9 are the silky modal version. Pink, orange, white, Oxford, Black 2, Navy 2, Red 2 and Blue 2 are the fine cotton version. Both share one jockstrap cut, which Rounderbum says molds to the body with less fabric. Two elastic straps run from the waistband around the seat and leave the backside exposed. A seamed contour pouch gives a defined front, and the brand calls the fit super stretch. The modal colours add a slim contrast stripe along the top of the waistband. The cotton colours keep a tonal band with Rounderwear lettering instead. Pick the Rounderbum Essentials Jockstrap for training days, nights out or simply a lighter layer. Find more men's jockstraps or browse the full Rounderbum collection at Underwear Expert.
