Product Insights

Le 31's Bird's-Eye Knit Washable Pant is a $89 CAD entry-level tailored straight fit that runs trim, so sizing up improves comfort. The polyester-viscose-spandex knit is thinner than dress trousers but wrinkle-resistant, machine-washable, and breathable via micro-openings. A concealed elastic waistband provides stretch and a smooth front, enabling beltless tucking or casual wear. The navy-black mélange reads as near-solid, pairing with black or navy, while the straight leg works with sneakers or dress shoes. The tradeoff is a lighter fabric that sacrifices traditional trouser weight for cool, fast-drying, low-maintenance versatility.

Verified claims

Sizing
The straight fit runs tight on most buyers; sizing up improves comfort.
Value
At $89 CAD, this pant is Le 31's entry-level tailored option.
Fabric
Thinner than traditional trousers; stays cool and dries fast, buyers note.
Breathability
Better airflow than standard trousers via knit's micro-openings.
Wrinkle resistance
Stretch viscose-polyester knit resists wrinkles exceptionally well.
Texture
Subtle raised-dot pattern appears semi-plain at distance and micro-textured up close.
Material
The polyester-viscose-spandex blend makes these pants thinner than dress trousers yet wrinkle-resistant and machine washable.
Formality range
Casual jeans-style, but bird's-eye texture and mélange allow dressing up; machine-washable.
Waistband flexibility
Concealed elastic waistband allows tucking without a belt or clean look with a belt.
Stretch comfort
Concealed elastic gives inches of stretch for a forgiving fit and all-day comfort with a tailored front.
Concealed elastic design
Elastic is channeled internally so the front lies smooth, enabling beltless tucking and a cleaner look.
Machine washability
Machine-washable across entire tailored pant range
Drying instructions
Tumble drying on low is safe; air drying flat preserves shape
Wash durability
Resists pilling and fading while maintaining softness after washing
Fit
Runs trim, size up; stretch fabric and elastic waistband offer comfort, but knit is lighter than typical.
Care
Machine-washable knit resists pilling and fading, retaining shape.
Shoe pairing
Uniform straight leg pairs with both sneakers and dress shoes without bunching.
Versatility
Navy-black mélange reads as a near-solid, pairing with both black and navy without clashing.
Styling
Straight fit works with sneakers and derbies, enabling monochromatic looks from casual to dressy.
Design details
Five-pockets and concealed elastic waistband allow polished tuck-in or casual wear.

Love love these pants!

Melssa I.

My husband loves his pants like this! A very nice trim fit. Very comfortable with the stretch but also very sharp and dressy looking! Fits a little on the small side. Ordered the next size up than we usually get and it’s perfect.

DONNA O.

A bit tighter than other pants but very nice material and length

Nice pant

Amy D.

The material isn't very thick, I was surprised by that. Definitely seem like they would have run tight. Due to other reviewers, I ordered a size up. It was almost too big for him but they'll do.
