Buying Guide

All-day comfort while sitting
For long days of sitting — like all-day wear or working from home — reviewers report this brief stays comfortable, crediting its anti-transpirant stretch fabric and wide waistband. Its overall fit is described as super comfortable, and the brief sits at the natural waist with full rear coverage.[1,2]
Packing for travel or the gym
Some customers report this brief holds up well in the wash, with the fabric and waistband staying intact. That easy care makes it a candidate for a travel or gym bag rotation, staying fresh between washes.[1]
Building a coordinated underwear drawer
For shoppers curating a coordinated drawer of everyday briefs, this nautical stripe brief adds a patterned option that's easy to buy again. One reviewer found the stripe pattern nice and owns it in several colors, which the reviews analysis takes as a sign of wardrobe versatility.[1]
Product comparison
Compared within this brand.
| Nautical Stripe Brief Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy brief in a breathable fabric blend of 47 percent TENCEL modal, 47 percent organic cotton, and 6 percent spandex. Reviewers describe the wide elastic waistband as a key comfort point for long periods of sitting, and report that washing does not degrade the fabric or waistband. It comes in a nautical stripe in the Patterned Red colorway across sizes small to extra-large; note that one image analysis observed the elasticized leg hems creating a slight inward curve and gathered look on the model.[1,2,3] | Striped-Band Brief Tencel™ Modal & Organic Cotton: Choose this if you want a soft, lightweight low-rise brief in an organic cotton and TENCEL™ modal blend (47/47 with 6% spandex) — reviewers describe the fabric as breathable and cool, and the cut sits just below the waist so it stays hidden under low-rise jeans or trousers, with a no-roll elastic waistband designed to stay in place. Note that reviewers report sizing runs about a size small and the crotch is cut at least half an inch narrower than competing briefs, so size up if you prefer a roomier pouch or aren't used to a snug fit. Some reviewers also say the updated Tencel™ version fits noticeably tighter than the original Le31 cotton briefs.[4] | 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, TENCEL™ modal, and 6 percent spandex, with an elastic ribbed waistband, double-layered front, and shaped front pouch. It comes in small through extra-large and four neutral colors including Purple Grey, Ivory/Cream Beige, Hazelnut, and Mossy Green, and shows full rear coverage on the model photographed. Note that fit and the dark mauve/plum tone are assessed from a single studio photo, so coverage and exact shade may vary by body and colorway.[5,6,7] |
