| Solid Stretch Jockstrap Tencel™ Lyocell: Choose this if you prefer a soft TENCEL™ Lyocell stretch jersey with a smooth, matte knit pouch fabric that contrasts with shinier woven elements on the wide elastic waistband and flat leg straps. This jockstrap features an open back and a single-panel contoured pouch, designed in Canada and manufactured in Portugal. It is available in black, brown, navy/midnight blue, and pink in sizes Small through X-Large.[1,2] | Striped-Band Brief Tencel™ Modal & Organic Cotton: Choose this if you want a low-rise brief in a soft, breathable stretch jersey of 47% organic cotton, 47% TENCEL™ modal and 6% spandex, with a no-roll elastic waistband that stays in place and a contoured, double-layered front. Reviewers describe the lightweight blend as keeping them cool through long days or warm weather, holding up crisp after multiple washes, and sitting low enough to disappear under low-cut jeans. Note that reviewers report the sizing feels a size small and the front pouch is cut at least a half-inch narrower than other briefs, so size up if you are not used to a snug pouch, and expect a tighter fit than the original Le31 cotton version.[3] | Neutral-Hued Stretch Brief Tencel™ Modal & Organic Cotton: Choose this if you want a low-rise brief in a soft stretch jersey of 47% organic cotton, 47% TENCEL™ modal, and 6% spandex, with an elastic ribbed waistband in a tonal shade, a double-layered front, and narrow same-color leg binding. It comes in four neutral colorways (Purple Grey, Ivory/Cream Beige, Hazelnut, Mossy Green) and sizes Small through X-Large, and is a Le 31 by Simons exclusive designed in Canada. In the product photos it shows full rear coverage while sitting low on the hips, though fit and coverage are observed on a single model and may vary by body and size.[4,5,6] |
