Product Insights
Le 31’s 2.5-inch inseam TENCEL modal–organic cotton trunk at $19 CAD undercuts Calvin Klein’s similar cut, using a double-layered no-fly front for smoothness under thin trousers and 6% spandex leg bands that resist sagging and ride-up, keeping the fit snug under 5-inch shorts while sizing from XS to XL for broader accessibility.
Verified claims
- Inseam length
- Shorter 2.5-inch inseam reduces bunching and ride-up compared to standard trunks.
- Value
- At $19 CAD, Le 31 undercuts Calvin Klein's cotton trunks at $22 for a similar 2.5-inch cut.
- Smooth front
- Double-layered front creates a smooth, discreet fit under thin trousers.
- Front panel
- No-fly double-layered front provides support, modesty, and a smooth contour.
- Care
- Cold gentle cycle, inside out, no softener, low heat or line dry.
- Material
- TENCEL modal–organic cotton blend gives silky-soft feel and premium durability.
- Sizing
- Available in six sizes XS to XL, broader than premium brands starting at Small.
- Brand story
- Le 31 is Simons' exclusive house brand, designed in Canada and sold direct, which keeps the trunk's cost focused on the TENCEL™ modal-organic cotton fabric rather than licensing mark-ups.
- Leg band recovery
- 6% spandex leg bands resist sagging and ride-up throughout the day
- Fit
- 2.5-in inseam and spandex legs keep trunk snug under 5-in shorts.
- Comfort
- The TENCEL™ modal in the blend is known for a silky, cool feel, though some buyers find the organic cotton texture comes through more than the modal.
- Sizing
- Le 31 trunks generally fit true to size compared to other trunk brands, though the 2.5-inch inseam feels shorter than average for a trunk.
- Waistband comfort
- Buyers highlight the waistband as a positive: one calls the large waistband a huge plus, and another describes it as good quality.

Comfortable
But a tad small for a medium- not a deal breaker though. Happy with them
Simple et confortable
Design intéressant, mais le boxeur ne résistera pas longtemps. Il sera rapidement trop grand pour taille moyenne. Suggestion, trouver manière d'indiquer le devant de l'arrière.
Excellent!

Très bon boxeur court
Je suis content d'avoir acheté ce boxeur court. Il est très confortable et soutien bien. La taille recommandé par le tableau de système de taille en ligne était exact. C'était ce qu'il me fallait. Je recommande.
Texture coton bien plus que modal et tencel
Les boxers sont excellent en terme de rapport qualité prix si un aime des boxer coton régulier. On est loin de la douceur du modal.

Very comfortable - needed bigger size!
Very comfortable great underwear! It does shrink a bit in wash & I do find I needed to go up a size than I expected. Sometimes I can getaway with a large but I definitely needed the extra large for these!
