Product Insights

A 3-inch stretch trunk from Le 31 at 20 CAD, in stock across sixteen color-and-size variants at a single price and a full SMALL-to-X-LARGE run, built on a 47% organic cotton, 47% TENCEL Modal, 6% spandex jersey whose core promise is a silkier, brighter, longer-lived fabric than cotton: the modal half runs about 1 dtex against cotton's 1.5-2.5 for a silkier hand, holds 11-13% moisture regain against cotton's 7-8% to release skin moisture faster, dyes a cleaner tone-in-tone shade, and washes softer and more shade-true where cotton dulls after roughly 25 cycles, while the 6% spandex governs recovery so the waistband and leg hems snap back after a full day; a doubled front in the same jersey adds show-through coverage on the palest colorways and washes as one fabric. The fiber is authenticated by an embedded molecular marker as genuine branded TENCEL rather than generic modal, sourced from FSC- or PEFC-controlled wood with Lenzing holding Canopy's Dark Green Shirt, made with at least 50% less carbon and water than generic modal, paired with organic cotton whose farming cuts global-warming emissions 46% versus conventional, and carrying TÜV-certified biodegradability. The color story is four colorways spanning four distinct undertone families, purple grey, ivory/cream beige, hazelnut and mossy green, not four depths of one neutral. The tradeoffs are explicit: buyers report the elastic waistband is the one uncomfortable spot on an otherwise soft trunk even though it stretches about 70% and springs back; the actual color reads duller than in the product photos; the modal is a modified viscose process, not lyocell; the certified biodegradability stops at the fiber, since the 6% spandex leaves the trunk not fully compostable; and tumble drying is acceptable only on low heat, with low heat or air drying needed to limit shrinkage. Rated 3.8 of 5 from four reviews.

Verified claims

Waistband fit
Buyers report the elastic waistband is the one uncomfortable spot on an otherwise soft trunk
Waistband recovery
The 6% spandex jersey stretches about 70% across and springs back, keeping the band snug
Color fidelity
A buyer reports the actual colour is duller than in the product photos.
Undertones
Purple Grey, Ivory/Cream Beige, Hazelnut and Mossy Green span four distinct undertone families, not four depths of one neutral.
Dye evenness
Modal and cotton dye a cleaner, more even tone-in-tone shade than cotton/viscose blends.
Shade retention
The modal knit holds its shade and reads brighter through repeated washing, unlike cotton.
Softness
The modal half runs about 1 dtex versus cotton's 1.5-2.5, giving the jersey a silkier hand.
Moisture wicking
The modal half holds 11-13% moisture regain versus cotton's 7-8%, releasing skin moisture faster.
Shape retention
The 6% spandex governs recovery, so the waistband and leg hems snap back after a full day.
Front construction
The doubled front uses the same 47/47 modal-cotton jersey as the body, adding coverage.
Fiber authenticity
TENCEL Modal fibers carry an embedded molecular marker that authenticates them.
Environmental impact
TENCEL Modal is made with at least 50% less carbon and water than generic modal.
End of life
The modal content is certified biodegradable; the 6% spandex in the blend is not.
Variant pricing
All sixteen colour-and-size variants are priced the same and are in stock.
Front coverage
Double-layered front adds show-through coverage on the palest colorways
Laundry
The doubled front is the same jersey as the body, washing as one fabric
Size range
Every colorway is stocked in the full SMALL to X-LARGE run.
Color palette
Four colorways span four distinct undertones: grey, cream, brown and green.
Color retention
The modal blend gets softer and keeps its shade with washing, unlike cotton.
Care
Tumble drying is acceptable, but low heat or air drying limits shrinkage.
Wash aging
The modal blend washes softer and brighter, where cotton dulls after about 25 cycles.
TENCEL authenticity
An embedded molecular marker authenticates the modal as genuine branded TENCEL, not generic modal.
Wood sourcing
The modal's wood is FSC- or PEFC-controlled, and Lenzing holds Canopy's Dark Green Shirt.
Water footprint
The reduced water footprint comes from the TENCEL modal, not the organic cotton.
Organic cotton
Organic cotton farming cuts global-warming emissions 46% versus conventional.
Certifications
TENCEL modal is FSC/PEFC-sourced and TÜV-certified biodegradable; the 6% spandex is not.
Biodegradability
TENCEL Modal fiber is TÜV-certified biodegradable; at 6% spandex the trunk is not fully compostable.
Material
47% organic cotton, 47% TENCEL Modal and 6% spandex; the modal is a modified viscose process, not lyocell.
Traceability
TENCEL Modal fibres carry a molecular marker that lets Lenzing authenticate them.
Sustainability
TENCEL Modal is made with at least 50% less carbon and water than generic modal.

Why and when to choose each product
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]
