| 3" Herringbone-Waist Trunk Tencel™ Modal & Organic Cotton 3-Pack: Choose this if you want a short 7.5 cm (3-inch) inseam trunk in a soft, stretchy jersey blend of 47% organic cotton, 47% TENCEL™ modal, and 6% spandex, with an elastic herringbone-patterned waistband. Each three-pack contains solid, logo-free trunks with a smooth matte finish, a double-layered contoured front pouch, and double-stitched hems, and comes in Black, Charcoal, or Navy/Midnight Blue in sizes small through extra-large. This Le 31 style is designed in Canada as an exclusive for Simons.[1,2,3] | Logo-Waist Classic Briefs Organic Cotton 3-Pack: Choose this if you want soft, breathable everyday briefs in a 95% organic cotton, 5% spandex stretch jersey — reviewers praise the soft waist elastic for staying in place without digging, and the low-rise cut with a discreet logo band sits below the natural waist so it won't peek above modern pants. The three-pack comes in Black, White, and Navy/Midnight Blue in sizes X-Small through X-Large, and per the review analysis it's a safe bet for buyers avoiding synthetic fabrics. Be aware that thigh openings run inconsistent (some too tight and chafing, others too loose), the low front seam offers less support and doesn't suit running or weightlifting, leg elastic can weaken after a few washes, and one long-term user insists on line drying rather than machine drying to preserve the fabric.[4,5] | Classic Solid Briefs Organic Cotton 3-Pack: Choose this if you want everyday briefs in soft, breathable 100% organic cotton, with reviewers crediting the moisture-wicking fabric and wide, soft waistband for all-day comfort in warm weather. The low-rise, slim-fit design comes as a three-pack in black, white, and navy/midnight blue across sizes small to XX-large. Note that reviews flag the size chart as unreliable, with most buyers sizing up or exchanging, and the cut and thin cotton may show lines or sit unflatteringly under slim-fit or tailored trousers, so they're better suited to relaxed fits.[6,7] |
