“To disclose - I have yet to swim in these. However, the fit, color and texture/skin-feel are great! There are no irritating seams or inconsistencies in fit for me, as well. Though separate to the section explicitly titled “tucking” (ie., the non-swim tucking underwear), the piece does just as well while stretching, walking, squatting and jumping for an AMAB body. Hopefully this item can be included in summer collections at big box stores in the future, like other items have prior.”
