Verified claims

Material
95% TENCEL™ Lyocell with 5% elastane.
Fabric feel
Soft, smooth, matte stretch jersey that feels cool and comfortable next to skin.
Moisture & heat
Lyocell absorbs and releases moisture to support a drier, cooler microclimate.
Odour
Efficient sweat absorption leaves less moisture on the fibre surface, creating a less favourable environment for odour-causing bacteria.
Stretch & recovery
The 5% elastane is a recovery component, not a high-stretch build.
Fit & sizing
Order by waist measurement: S 28–30", M 32–34", L 36–38", XL 40–42"; no need to size up.
Inseam & rise
3" inseam with a low-to-mid rise trunk cut.
Ride-up tradeoff
Short legs have less surface to hold the thigh, so they ride up more easily if thighs touch.
Best for
Best for slim or tapered trousers and wearers whose thighs do not rub much or who already like short cuts.
Waistband
Soft elastic waistband intended to lie flat; a rolling band points to rise or size, not inseam.
Front construction
Double-layered front with a shaped pouch panel and contour seams.
Leg hems
Narrow single-stitch hems lie flat against the upper thigh.
Surface & styling
Smooth matte solid knit with no visible exterior logo.
Colors & variants
Four colors (Black, Brown, Navy/Midnight Blue, Pink) across S–XL, 16 combinations.
Black
Black is the concealment default.
Navy
Navy/Midnight Blue is the coherent choice under blue bottoms.
Brown
Brown is the only warm neutral for khaki, olive and earth tones.
Pink
Pink is the deliberate non-neutral option.
Care
Machine wash, do not bleach, tumble dry.
Durability
Dark lyocell can grey or fade with repeated washing; recovery is the key long-term property.
Value & provenance
29 CAD for a Le 31 by Simons exclusive designed in Canada and made in Portugal.

Why and when to choose each product
3" Solid Stretch Trunk Tencel™ Lyocell: Choose this if you want a low-rise trunk with a short 7.5 cm (3 inches) inseam, cut from soft stretch jersey made of 95 percent TENCEL™ Lyocell and 5 percent elastane, with an elastic waistband and a double-layered front. It suits shoppers who prefer a logo-free exterior (as noted from the rear view only) and comes in Black, Brown, Navy/Midnight Blue, and Pink in sizes Small through X-Large. This Le 31 design is made in Portugal, and the fit described was observed on a model, so it may vary by body.[1,2]3" Neutral-Hued Stretch Trunk Tencel™ Modal & Organic Cotton: Choose this if you want a soft, stretchy trunk in a blend of 47% organic cotton, 47% TENCEL™ modal and 6% spandex, with a short 3-inch inseam, double-layered front, and an elastic waistband. It is a Le 31 by Simons exclusive designed in Canada, offered in four neutral colors and four sizes. Note that one customer review found the elastic waistband uncomfortably tight, and one reported that the actual color looked duller than in the product photos.[3]3" Solid Breathable Trunk Lenzing™ Ecovero™ Viscose: Choose this for a soft and fluid fit made from LENZING™ ECOVERO™ viscose, which is sourced from certified renewable wood and is designed to keep you cool and dry. Although the silky-soft and breathable construction offers universal praise, some find that the support feel is lighter than in previous versions or that the fabric appears thinner.[4]
