Product Insights
Le 31's 5-inch neutral-hued stretch boxer brief, at $19 CAD, blends 47% organic cotton, 47% TENCEL modal, and 6% spandex for a soft, moisture-wicking, shrink- and fade-resistant fabric that dries faster and has high bursting strength. It features a double-layered front panel for support without a fly, a 5-inch inseam to prevent leg-line peek-out, and requires cold wash/low tumble drying. Its sustainable materials use closed-loop production with 10–20× less water and lower carbon. The main tradeoff is a simpler support design versus specialized pouches and a no-fly front that saves cost but may not suit all preferences.
- Softness
TENCEL modal fiber is three times softer than cotton.
Why this is supported
The TENCEL modal fiber in these boxer briefs is three times softer than cotton at the fiber level. According to a textile source,
Modal is three times softer than cotton, so you’ll notice the difference as soon as you put it on.
friendtex.comThis translates to a silk-like surface that reduces friction and chafing against the skin.
- Moisture
Absorbs 40–50% more moisture than cotton, wicking sweat and drying faster.
Why this is supported
The TENCEL modal in the blend absorbs 40–50% more moisture than cotton. As xiaotex.com states,
cotton absorbs roughly 40-50% less moisture than Modal or Lyocell.
xiaotex.comCombined with organic cotton, this provides balanced moisture management, pulling sweat away and keeping the wearer cool and dry.
- Shrink & fade resistance
TENCEL modal content provides inherent resistance to shrinking, fading, and wrinkling.
Why this is supported
The 47% TENCEL modal content gives the fabric inherent resistance to shrinking, fading, and wrinkling. According to friendtex.com,
Modal resists shrinking, wrinkling, and fading, so your underwear looks and feels new longer.
friendtex.comThe recommended care routine further protects the organic cotton from shrinkage:
For best care, machine wash cold and tumble dry low. This standard method helps maintain the quality of TENCEL™ modal and organic cotton blends.
What is the recommended care (wash temperature, drying method) to maintain fabric quality?Together, material and care help these briefs retain their fit and colour over many washes.
- Fabric
Lab-tested highest bursting strength among cellulosic blends; resists shrinkage.
Why this is supported
Independent testing shows that
Plain knitted fabrics from modal/cotton blended yarns have the highest bursting strength values.
cotton.orgMeanwhile, modal fibers are noted to resist shrinkage:
Modal resists shrinking, wrinkling, and fading, so your underwear looks and feels new longer.
friendtex.comTogether, these properties confirm the blend's durability against tearing and distortion.
- Support design
Double-layered front panel provides everyday hold, simpler than BN3TH's 3D pouch.
Why this is supported
Le 31 uses a double-layered front panel for support, a simpler construction than BN3TH's patented 3D pouch. This design still offers everyday hold and avoids potential pouch alignment issues, while maintaining a significantly lower price.
- Value
Costs $19 CAD, nearly half Stanfields' $34 CAD for a similar TENCEL modal brief.
Why this is supported
The Stanfields TENCEL modal boxer brief retails for $34 CAD (quoted at
$24.00 USD
stanfields.comper its website), while Le 31's comparable brief is priced at $19 CAD. The deep discount is possible because Le 31 is a Simons private label, sold directly without wholesale margins. The identical premium fiber (TENCEL modal) is confirmed in the product description:
Soft, stretch jersey in a blend of organic cotton and TENCEL modal
stylight.ca— thus the value comes from the distribution channel, not a compromise in fiber quality.
Simons’ private-label distribution bypasses wholesalers, enabling Le 31 to sell at $19 CAD while comparable modal-cotton boxer briefs from BN3TH Essentials ($28 CAD) and Stanfields (~$34 CAD) are priced 30–45% higher.

- Care
Cold wash and low tumble dry preserve the support panel's elasticity.
Why this is supported
The brand recommends:
For best care, machine wash cold and tumble dry low. This standard method helps maintain the quality of TENCEL™ modal and organic cotton blends.
What is the recommended care (wash temperature, drying method) to maintain fabric quality?High heat degrades elastane and would cause the support panel to lose shape.
- Sustainable materials
47% organic cotton, 47% TENCEL modal, 6% spandex: closed-loop, 10–20× less water, lower carbon, certified organic.
Why this is supported
The boxer briefs are a blend of 47% organic cotton, 47% TENCEL modal, and 6% spandex. The TENCEL modal is produced in a closed-loop process:
The cotton portion is certified organic; as stated,
Stylight.ca lists the product as
, which confirms the inclusion of organic cotton. This contrasts with competitors like Stanfields, whose modal-cotton boxer brief does not claim organic certification.
The material is
Soft, stretch jersey in a blend of organic cotton and TENCEL modal
stylight.ca, and the product listing specifies 47% organic cotton, 47% TENCEL modal, 6% spandex. TENCEL modal offers several advantages:
Modal resists shrinking, wrinkling, and fading, so your underwear looks and feels new longer.
friendtex.comAdditionally,
