Product Insights
Le 31's 3" stretch trunk, 20 CAD flat across all sixteen colour-and-size variants with no X-Large or colour premium, builds its case on fiber physics rather than trim: the TENCEL modal half runs about 1 dtex against cotton's 1.5-2.5 for a silkier hand, moves more air than an all-cotton knit, holds 11-13% moisture regain versus cotton's 7-8% to release skin moisture faster, resists pilling and dyes a cleaner tone-in-tone shade than cotton/viscose, while the 47% cotton share supplies jersey body instead of all-modal thinness and the 6% spandex stretches roughly 70% across so the waistband and leg hems spring back after a full day; the modal-cotton-and-spandex blend is what the on-garment Vision label covers at 94% of content, nearly double the 50% threshold, though that tag measures carbon and water reduction only, not biodiversity, soil toxicity or ocean pollution. The silhouette is deliberately minimal: a 3-inch inseam, a full inch shorter than the shortest boxer briefs, with little fabric to ride up and enough restraint to stay tucked under slim chinos and tailored trousers where a boxer brief's leg can peek out, cut for slim-to-athletic builds and running true to size across S 28-30in to XL 40-42in, stocked in full size runs within four colorways spanning grey, cream, brown and green undertones whose darker neutrals read deeper and more saturated than an all-cotton knit. The tradeoffs are narrow and specific: the elastic waistband is the one uncomfortable spot on an otherwise soft trunk and thicker thighs fit a boxer brief better, a buyer reports the actual colour is duller than the product photos, modal retains only 50-70% of its dry strength when wet and so needs cold washing without fabric softener plus low or air drying to protect the spandex and limit shrinkage, and the review base is thin at 3.8 stars from four reviews, making the fiber-level breathability, wicking and recovery story the reliable case rather than social proof or colour accuracy.
Verified claims
- Fabric weight
- The 47% cotton share gives the jersey body rather than all-modal thinness.
- Softness
- The modal half runs about 1 dtex versus cotton's 1.5-2.5, giving the jersey a silkier hand.
- Breathability
- The modal-cotton jersey moves more air than an all-cotton knit.
- Moisture wicking
- The modal half holds 11-13% moisture regain versus cotton's 7-8%, releasing skin moisture faster.
- Pilling
- The modal jersey resists pilling better than the same knit in cotton.
- Dye evenness
- Modal and cotton dye a cleaner, more even tone-in-tone shade than cotton/viscose blends.
- Shape retention
- The 6% spandex governs recovery, so the waistband and leg hems snap back after a full day.
- Waistband recovery
- The 6% spandex jersey stretches about 70% across and springs back, keeping the band snug
- Waistband fit
- Buyers report the elastic waistband is the one uncomfortable spot on an otherwise soft trunk
- Care
- Wash cold and skip fabric softener; dry low or air dry to protect the spandex and limit shrinkage.
- Durability
- Modal holds 50-70% of its dry strength when wet, outlasting a viscose knit.
- Wet strength
- TENCEL modal retains 50-70% of its dry strength when wet, outlasting a viscose knit in the wash.

| 3" Neutral-Hued Stretch Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy short trunk with a 3-inch inseam, made from 47% organic cotton, 47% TENCEL modal, and 6% spandex, in a fitted low-rise cut with a double-layered front, smooth no-logo exterior, and four neutral colorways from Small to X-Large. One customer review noted the elastic waistband may feel uncomfortably tight, and the actual color can appear duller than in product photos, so factor that in if either matters to you.[1,2] | 3" Colourful Stretch Jersey Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy trunk made of 47% organic cotton, 47% TENCEL™ modal, and 6% spandex, with a low-rise silhouette, a 3 inch inseam, and a wide white elastic waistband that sits below the navel. It suits shoppers who prefer a plain, single-color look, available in Green, Blue, and Red in sizes Small through Large, though the variant data lists X-Large only for the Red colorway.[3,4,5] | 2.5" Striped-Band Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy everyday trunk in an organic cotton and TENCEL modal blend: reviewers report all-day comfort at the office and relaxed lounging, with a stay-put wide waistband and a 2.5 inch inseam on a low-rise cut. It suits shoppers drawn to more sustainable materials, though some report noticeable shrinkage after washing and suggest sizing up, and the cotton blend can trap heat during high-intensity workouts while a few note durability may be a trade-off.[6,7] |
