WonderHip comes in all sizes (XS, S, M, L, XL, 2XL, 3XL, 4XL) with white briefs as standard, and is available in black as well. WonderHip Access is identical with the white briefs, and sports a buttoned opening between the legs for easy access to diapers etc.
The briefs are fashion-knitted, which means there are no seams othe than the inside pockets that keep the cushions in place. They wash like ordinary underwear.
