We made the unsung wardrobe heroes you've been missing. The best basics—underwear, perfected. This high-rise thong boasts maximum coverage without any visible lines on your backside. It will sit at your natural waist and under the waistband of our high-rise denim styles. With a tonal elastic band and soft trim, it's made from sustainable cotton jersey blended with modal for a smooth, light-as-air feel and second-skin fit (like it's barely there). You shouldn't have to think about underwear—leave that to US. We've thoughtfully engineered each pair to feel so comfortable you'll forget you've got anything on at all.

Why UltimateS?

  • The elastic waistband has a comfortable width and sits flat without cutting in.
  • The ultra-high rise offers maximum coverage and a secure fit; designed to be worn with your favorite jeans from US.
  • Our sustainable so-soft cotton jersey is blended with modal to feel smooth and move with you.
  • They're lightweight, breathable, antimicrobial, and moisture-wicking.
  • The generous gusset width is graded per size.
  • The soft and stretchy trim allows for flexible leg openings that sit flush without digging.
