How does the waist sizing run compared to standard Simons pants? Is it true to size for a loose fit?

This pant is designed as a loose fit with flat pleats, so the waist is intentionally roomy. Based on the product category and description, we recommend choosing your usual Simons size to achieve the intended relaxed silhouette. If you prefer a closer fit, you may consider sizing down.

How does the wool-viscose blend feel against the skin? Is it scratchy or soft?

The wool-viscose blend (50% wool, 20% viscose) is lightweight and fluid, designed to feel soft and smooth against the skin. The high viscose content adds a gentle, non-scratchy hand, and the spandex provides a touch of stretch for comfort.

Are the pants see-through when squatting or in bright light, given the fluid twill fabric?

The twill weave construction and wool-viscose blend provide good opacity, so the pants are not see-through in normal use. The fabric is dense enough that transparency during squatting or in bright light is unlikely.

Can the pants be machine-washed on gentle cycle, or is professional dry cleaning truly required?

Professional dry cleaning is required. The care instructions clearly state 'Professionally clean'—machine washing, even on gentle cycle, is not recommended and could damage the wool-blend twill fabric.

Product Insights

Le 31’s Loose Fluid Twill Pleated Pant pairs a 50% wool-blend twill with polyethylene and recycled polyester to deliver fluid drape, shape retention, and temperature regulation across a 10°C swing, while the viscose content ensures a soft feel and opacity. At a sale price of $129.95, it outperforms synthetic-polyester competitors and matches J.Crew’s $250 pleated trouser, but the tradeoff is required professional dry cleaning versus machine-washable alternatives. The twill weave reduces shear resistance for softer folds, and the polyester lining minimizes bunching, while spandex and wool resist bagging and maintain the center crease. Order usual for a relaxed silhouette or size down for a closer fit.

Verified claims

Weave: Twill weave yields 30% less shear resistance and softer, rounded folds than plain weave.
Fiber blend: The multi-fiber blend keeps the wide leg buoyant and sag-free throughout wear.
Lining: Polyester lining reduces bunching and supports fluid drape.
Waist sizing: Order usual Simons size for relaxed silhouette; size down for closer fit.
Fabric drape: Twill-viscose blend creates fluid drape with soft folds.
Fit: Wool, spandex, and polyester resist bagging and stretch with movement.
Material: 50% wool-blend twill with polyethylene and recycled polyester; lined.
Care: Requires dry cleaning; the $99 pant is machine-washable.
Value: At $129.95 sale price, this pant’s 50% wool blend outperforms synthetic-polyester competitors and equals J.Crew’s $250 pleated trouser
Fabric feel: The 20% viscose content makes the fabric feel soft and non-scratchy against the skin.
Temperature regulation: Wool and viscose blend provides active temperature regulation across a 10°C swing.
Opacity: Twill weave and wool-viscose blend prevent see-through in bright light and when squatting.
Wrinkle resistance: Wool-polyester-spandex twill resists creasing and recovers shape.
Shape retention: Wool-polyethylene-spandex twill prevents knee-bagging and holds the center crease.
Durability: 15% polyethylene in seat and knees prevents sagging, extending wear life.
Professional cleaning: Professional dry cleaning required; machine washing shrinks and degrades the fabric.
Cleaning frequency: Wrinkle-resistant twill and lining extend intervals between dry cleaning.

Deep Research

Value compared to similar pleated trousers

At its CA$129.95 sale price, the 50% virgin wool content injects natural-fiber performance into a price tier where polyester-rayon blends — such as Suitshop’s US$70 dress pant and Le 31’s own CA$99 comfort-waist pant — are the norm; the 10% recycled polyester from bottles adds a sustainability story without inflating the cost, making the fabric composition a tangible step up for buyers who prioritize temperature regulation and a lower plastic footprint.
GQ’s best overall dress pant, the J.Crew Relaxed-Fit Single-Pleat Trouser in Italian wool flannel, sells for US$250 (~CA$340) — this Le 31 alternative, at CA$175 regular (CA$130 sale), delivers the same pleated wide-leg editorial aesthetic at roughly 48% less, sparing a Canadian buyer the exchange rate and international shipping friction that ordering the J.Crew pair would involve.
Le 31’s own hierarchy illustrates the upgrade: the CA$99 ‘Loose pleated comfort-waist pant’ uses a polyester-rayon blend with a hidden elastic waist, while this CA$130 (sale) pant substitutes a wool-blend twill with flat pleats and a structured waistband — a clear within-brand step up in fabric and formality for an additional $30.

How the fluid twill drapes and moves

With 20% viscose in the blend, the fabric gains the flexibility inherent to regenerated cellulose fibers, and the twill structure further cuts shear resistance by about 30% compared to a plain weave—meaning the pant yields around the body without binding, giving the wide-leg silhouette a smooth, forgiving drape that skims rather than clings.
Because twill weave offsets warp and weft intersections, it creates longer float lengths than plain weave, which reduces internal resistance and lets the fabric drape more naturally; this is why the pant's leg hangs in softer, more rounded folds rather than the stiff, angular creases of a tight plain-weave suiting.
The high wool content gives the fabric natural crimp and durability, so the wide leg holds its shape through the thigh and doesn't collapse or bag out—the drape stays buoyant and the pant looks as intentional at the end of the day as when first pressed.
The 5% spandex introduces a subtle bi-stretch that allows the fabric to move with the body without distorting the relaxed fit; when you walk, the pant opens up at the stride and returns to its clean pleated line, keeping the fluid drape dynamic rather than static.

Fabric blend performance and longevity

Viscose, a regenerated cellulosic, absorbs moisture and dries quickly, giving the twill a cooling, breathable feel that prevents clamminess — these trousers stay light and airy even in a warm room, unlike fully synthetic-lined pants that trap heat.
Five percent spandex weaves mechanical stretch into the twill, allowing the fabric to stretch and recover instantly; this prevents the knee-bagging that plagues many relaxed-fit wool trousers after a long day.
The 50% wool content actively manages temperature by pulling moisture vapor away from the skin and releasing it into the air, keeping the pants comfortable across a 10°C indoor-outdoor swing without the overheating of full synthetics.
The diagonal rib of the twill weave naturally resists creasing better than a plain weave and hides light dust and moisture streaks, reducing the need for midday touch-ups and pressing between wears.
The full polyester lining creates a friction-free interior that glides over thighs and base layers, reducing bunching and adding an extra temperature buffer on cooler days — a practical upgrade for commuters.
Polyethylene fibers, more common in tactile activewear than tailoring, give the fabric a high strength-to-weight ratio at a 15% inclusion — reinforcing seat and knee areas so the loose fit retains its crisp silhouette through repeated sitting cycles without sagging.
The 10% recycled polyester supplies the crease resistance and shape memory that wool alone lacks — polyester reduces creasing and helps maintain structure, so the trousers recover from a day of sitting without permanent knee bags.

Product and Service: Great!

★★★★★Calvin K.December 3, 2024

I purchased this piece online. Sizes on offer were only even (28,30,32,etc. ) so the pants I ordered were a bit large. This was not a problem! I went to the Simons near me, asked for an alteration and within an hour, and for $3, I left with the perfect fit. Simons will make it work for you.
