Product Insights
Le 31's Optical Check Linen Shirt in modern fit combines 55% linen and 45% organic cotton for a soft, breathable, and cooling shirt that reduces creasing by 30-40% versus pure linen, with hollow flax fibers conducting heat 5x faster than cotton. It is true to size (size down for fitted, up for relaxed), improves with age, and features FLAX FIBRE certification for sustainable flax sourcing. The tradeoff is sizing precision and a price that offers certified fiber quality below fully certified linen alternatives.
- Sizing
Le 31 is true to size; between sizes, size down for fitted or up for relaxed.
Why this is supported
Le 31 is consistently rated true to size by third-party reviews:
Le 31 is true to size. Simons' men's line — classic cuts, true to size
thisfits.app. The brand also offers specific between-size guidance:
Le 31 fits true to size, so when you are between sizes, pick based on how close you want the cut to feel. Sizing up gives a relaxed feel and sizing down gives a more fitted silhouette.
thisfits.app. This guidance is reinforced by the fact that Le 31 shows low variation across categories, and while the listing does not include specific chest and waist measurements, the true-to-size baseline and between-size advice provide a reliable basis for size selection.
- Fabric comfort

Why this is supported
The cotton-linen blend is designed for immediate comfort: '
The result is a fabric that feels more comfortable against skin from the first wear
rottenhand.com'. Its breathability further supports the close fit: '
For hot-weather dressing, choose open weaves and relaxed but tailored cuts: a shirt that skims the body without clinging moves air far better than one worn tight.

thisfits.app- FLAX FIBRE certification
Certifies raw flax fiber that is rain-fed, non-GMO, field-retted, and zero-waste from European Flax.
Why this is supported
The Masters of FLAX FIBRE™ certification is fiber-level: the certified fibre is the raw material at the origin of full Masters of LINEN™, per the Alliance for European Flax-Linen Hemp:
Masters of FLAX FIBRE™ certified fibre is the raw material at the origin of all Masters of LINEN™ certified Linen.
allianceflaxlinenhemp.euThe specification also requires that flax be
from European Flax® fibre: no irrigation*, no GMO, no waste, field retting, mechanical scutching
assets.ctfassets.net, verifying the environmental and processing standards behind the certification.
- Price value
At $49.95, offers fiber-level certification below full-process certified linen shirts.
Why this is supported
The Masters of FLAX FIBRE™ certification is fiber-level, meaning the certified fibre is the raw material at the origin of the full Masters of LINEN™ mark:
Masters of FLAX FIBRE™ certified fibre is the raw material at the origin of all Masters of LINEN™ certified Linen.
allianceflaxlinenhemp.euThis fiber-level certification, paired with the shirt's blend of 55% certified linen and 45% organic cotton, provides verifiable environmental standards at a price below fully process-certified linen shirts, especially at the current sale price of $49.95 CAD.
- Softness
Linen-organic cotton blend eliminates break-in; soft from first wear.
Why this is supported
The organic cotton offsets natural pectin stiffness in new flax, making the fabric comfortable immediately.
The result is a fabric that feels more comfortable against skin from the first wear
rottenhand.comPure linen's
pectin breaks down over the first three to five washes, and the fabric softens considerably each time
rottenhand.com, so this blend eliminates the typical break-in period. Despite the shirt's
cut to hug the body with fitted shoulders and narrow sleeves
How does the modern fit compare to a regular fit in terms of chest and waist measurements for each size?, the immediate softness prevents any restrictive stiffness. As the linen wears, it continues to improve:
Linen is one of the rare materials that genuinely gets better the more you wear it and wash it. It doesn't weaken. It just loosens up and drapes more naturally.
rottenhand.comThis means the shirt's comfort deepens over time.
- Wrinkle reduction
Linen-cotton blend reduces creasing 30-40% vs pure linen.
Why this is supported
The organic cotton adds recovery, reducing creasing
reduce creasing by roughly 30 to 40 percent compared with pure linen
lovau.com.
- Breathability
Hollow linen fibers conduct heat 5x faster than cotton; modern fit stays airy.
Why this is supported
Linen's hollow fibers conduct heat away faster:
Linen is made from the flax plant. Its fibres are hollow and conduct heat away from the body roughly five times faster than cotton does.
lovau.comThe modern fit is cut to avoid trapping heat:
a shirt that skims the body without clinging moves air far better than one worn tight
lovau.comThis keeps the shirt airy from first wear.
- Cooling performance
Hollow flax fibers conduct heat 5x faster than cotton and wick moisture for rapid evaporation.
Why this is supported

lovau.comfrom European Flax® fibre: no irrigation*, no GMO, no waste, field retting, mechanical scutching
assets.ctfassets.netDespite the modern fit's closer cut, the open-weave fabric allows continuous airflow across the skin, preventing heat buildup. For those who prioritize maximum airflow, the same pattern is available in a comfort fit with a straighter cut that provides even more room.
- Aging benefits
Shirt improves with age: softer, less wrinkled, more durable each wash.
Why this is supported
The 55% linen, 45% organic cotton blend is designed to improve over time. As one source notes,

A bit misleading
When the shirt is advertised as linen but comes in as mixed with cotton, I feel that’s click bait. So I was disappointed in the fibre. However it turns out it feels great on and fits perfect. So the gift receiver is happy.
