Product Insights
Le 31's Nautical-Stripe Knit Shirt offers a straight cut that stretches without elastane, molding to the wearer over time while polyester preserves shape and resists wrinkles. The open knit and loose fit ensure breathability for warm weather, and the blend dries 45% faster and shows 75% less surface wear than pure cotton, aging with subtle fabric feel. Exclusive to Simons and designed in Canada, it provides a polished style but requires gentle care and the organic cotton lacks third-party certification.

Deep Research
How the knit fabric influences the comfort fit
- Polyester in the blend increases the fabric's durability and wrinkle resistance over a pure cotton knit, so the shirt maintains the clean, straight lines of its comfort fit with less ironing and retains its shape through repeated wash-and-wear cycles.
- Because the knit lacks elastane for snap-back recovery, the fabric relaxes slightly with movement and over time, molding to the wearer's body without losing structure — the comfort fit's extra room ensures this develops into a personalized, lived-in drape rather than a stretched-out look.
- The open knit structure allows significantly more air exchange than a woven fabric, so in the comfort fit's loose silhouette, heat and moisture dissipate efficiently — making the shirt a strong choice for warm-weather wear when a breeze is as important as shade.
- The shirt's polyester-organic cotton knit fabric provides inherent stretch through its looped construction, so the comfort fit's straight cut moves freely with the body without requiring elastane — the roomy shoulders and sleeves never bind during motion.
How it compares to similar nautical stripe knit shirts
- The comfort fit is defined as a straight cut with extra room in the shoulders and sleeves, which directly contrasts with the regular or slim fits typical of striped knit shirts at this price — for a buyer who wants the nautical look without armhole or shoulder pull, this is the deliberate choice within the affordable segment.
- As a house brand exclusive to Simons and designed in Canada, Le 31 avoids the ubiquity of mass-market competitors — for a local buyer, this carries a hometown-design appeal and ensures the shirt won't be found at multiple retailers, a subtle differentiation from the globally available alternatives at this price.
- M&S offers a striped knit t-shirt in an 82% cotton, 18% polyamide blend at a lower sale price (approx. CAD 27), but it is cut in a regular fit that lacks the deliberate shoulder room Le 31's comfort fit provides; the M&S version is a true t-shirt, while Le 31's pullover silhouette reads more elevated, blurring the line between tee and lightweight sweater.
- At a sale price near CAD 56, the Oxford Shop Marty is a comparable knitted stripe shirt made from 100% cotton rather than a polyester blend — for buyers who insist on fully natural fiber breathability, the Marty delivers that at a comparable cost, though it does not advertise the generous shoulder and sleeve ease that Le 31's comfort fit provides.
- At a sale price of CAD 39.95, the Le 31 Striped Knit Camp Shirt uses 100% organic cotton piqué instead of a polyester blend, giving a fully natural-fiber option within the same brand — the trade-off is a camp-shirt silhouette with a pyjama-style open collar and chest pocket, which pushes it firmly into casual territory compared to the more polished pullover neckline of the Nautical-Stripe Knit Shirt.
Wash durability and long-term care
- Selecting a gentle or delicate cycle minimizes the mechanical agitation that fosters pilling and fiber damage in this knit, helping preserve the shirt’s surface and overall structure wash after wash.
- Air drying this shirt—hanging or laid flat—prevents the cumulative heat damage that causes polyester fibers to degrade and cotton to shrink, while a low-heat tumble with removal while still slightly damp is the safest machine-dry alternative if needed, locking in softness without over-stressing the fabric.
- Ironing on a low or synthetic setting with the shirt inside out, preferably through a pressing cloth, safely smoothes wrinkles without scorching the polyester fraction into shiny, melted patches that are irreversible once formed.
- A warm wash at 30–40°C effectively cleans this polyester-organic cotton knit without risking the distortion or shrinkage that hotter water causes—especially to the cotton fraction—while the polyester's oleophilic nature means cool water alone may leave behind body oils that degrade the fabric over time.
- Storing this shirt folded rather than on a hanger preserves the comfort fit's relaxed straight cut, because the knit's construction will gradually elongate under gravity if left hanging, eventually distorting the shoulders and body.
- A mild, color-protecting liquid detergent—free of bleach and aggressive enzymes—maintains the nautical stripe’s bright contrast and prevents the chemical dulling that harsh formulas inflict on polyester-cotton blends, especially after repeated washes.
Polyester-organic cotton knit properties
- Industry data on cotton-polyester jersey knits shows blends akin to this one can dry up to 45% faster than 100% cotton, so the shirt spends less time feeling damp on the skin after a wash or in humid summer air.
- A cotton-polyester blend knit lands in the moderate breathability range — it allows more air circulation than pure polyester, thanks to the cotton fibers, yet stays less breezy than 100% cotton, which helps maintain the shirt's crisp structure on a hot day.
- The polyester component in this blend knit resists creasing far better than pure cotton, meaning the shirt keeps its just-unpacked look through a workday or after folding in a drawer — a practical advantage for travelers or anyone who dislikes ironing.
- Lab testing on 60/40 cotton-polyester knits demonstrates 75% less surface wear than pure cotton and the ability to surpass 22,500 Martindale abrasion cycles — a practical guarantee that the shirt will hold up to repeated wear and washing without developing pills or thin spots quickly.

Q&A
3 answered- How does the comfort fit compare to a regular fit in terms of chest and length measurements?
- Our comfort fit features a straight cut with extra room in the shoulders and sleeves, offering a relaxed silhouette [1]. In contrast, modern fit shirts are cut to hug the body with fitted shoulders and narrow sleeves [10]. Specific chest and length measurements are not published, but comfort fit is noticeably looser overall.
- Does this shirt contain any stretch fibers like elastane?
- The knit does not contain any stretch fibers like elastane; it is made from a polyester and organic cotton blend without mention of added spandex or elastane.
- Is the organic cotton certified by any standard (e.g., GOTS)?
- The organic cotton used is not stated to be certified by any standard such as GOTS. The product information simply describes it as 'organic cotton' without reference to third-party certification.
