Compared within this brand.
| Solid Stretch Brief Tencel™ Lyocell: Choose this if you want a classic low-rise brief in soft TENCEL™ Lyocell stretch jersey (95% lyocell, 5% elastane) with an elastic waistband that sits low on the hips. It offers a double-layered front with a shaped pouch and structured seam panels, plus full rear coverage as shown on the model. Made in Portugal from Le 31, a brand exclusive to Simons and designed in Canada; note that the waist position shown reflects one model photo, so fit may vary.[1,2,3] | Neutral-Hued Stretch Brief Tencel™ Modal & Organic Cotton: Choose this if you want a low-rise brief in a soft, stretchy jersey blend of organic cotton and TENCEL™ modal (47% each, plus 6% spandex), part of Le 31 by Simons, an exclusive designed in Canada. It has an elastic ribbed waistband, a double-layered front with a shaped pouch, tonal narrow leg binding, and a center back seam, in four neutral colorways from Purple Grey to Mossy Green and sizes Small through X-Large. Note that the fit and full rear coverage shown are observed on a single model in studio photos, so how it sits low on the hips may vary by body and size.[4,5,6] | Striped-Band Brief Tencel™ Modal & Organic Cotton: Choose this if you want a soft, lightweight stretch brief in an organic cotton and TENCEL modal blend, with a no-roll elastic waistband that stays in place and a low-rise cut that reviewers say disappears under low-cut pants — a good match for athletic or slim-fit builds who like a secure, second-skin feel. Note that reviewers report the front pouch runs at least a half inch narrower than other brands and the sizing feels a size small, so size up if you prefer more room, and expect a tighter cut than the original Le 31 cotton version if you're a legacy fan.[7] |
