Stretch Supima® Cotton T-Shirt Standard Fit

Le 31's Stretch Supima® Cotton T-Shirt (Standard Fit, CAD 39) delivers a tailored clean silhouette using 96% SUPIMA® cotton and 4% spandex—extra-long staple fibers ensure superior strength, softness, and color retention, while the spandex provides stretch recovery that prevents bagging, maintaining shape without clinging. The medium-weight opaque jersey works for both dressed-up and lounge wear, with black colourway fading less than standard tees. However, shoulder seam puckering has been reported on some units, disrupting the intended drape; sizing consistency across colors may lead some buyers to size up for broader shoulders. Priced roughly half of premium DTC tees and $12 above Uniqlo's Supima, it balances durability (resists pilling and thinning) with specific care needs (cold wash, low heat). Simons' 180-year heritage backs the 'Designed in Canada' mark.

Supima quality

The 96% SUPIMA® cotton, 4% spandex blend uses certified extra-long staple fibers for superior strength, softness, and color retention.

Why this is supported

The SUPIMA® trademark on the label guarantees the cotton is American-grown extra-long-staple with strict quality standards.

SUPIMA® registered trademark on the label is the strongest signal of high-quality extra‑long‑staple cotton available at retailHow the price compares to similar tees — certified_supima_fiber

This fiber length translates to measurable benefits: the fibers are up to 50% stronger than standard cotton and 35% longer, reducing pilling.

up to 50% stronger than standard cottonHow the stretch fabric works — supima_fiber_length_strength

Supima cotton fibers are 35% longer than standard upland cotton, which mechanically reduces the number of loose fiber ends on the yarn surface that cause pillingHow the price compares to similar tees — durability_and_fiber_length

The long fibers also create a silky feel and hold dye uniformly, while the spandex prevents bagging and Supima resists shrinkage, preserving the tee's appearance through many washes.

The SUPIMA® trademark certifies American‑grown extra‑long‑staple cotton that holds dye uniformly and resists pilling. As the certified Supima research details:

. The 4% elastane provides genuine two‑way stretch that maintains shape:

. With proper care (cold wash, low dry), shrinkage is minimal:

. Buyers confirm the material holds color and resists wear over time:

The extra-long staple fibers of SUPIMA cotton create a smoother yarn surface:

Supima cotton's extra-long staple fibers — a minimum of 1-3/8 inches — are up to 50% stronger than standard cotton, which means the yarns are smoother, less prone to pillingHow the stretch fabric works — supima_fiber_length_strength

This results in a fabric that reviewers describe as

The medium weight is confirmed as

a medium-weight Supima cotton jerseyWhat is the weight or thickness of the fabric (e.g., light, medium, heavy)?

which provides a balance of durability and softness. The longer fibers also mechanically reduce pilling:

The SUPIMA certification adds third-party verification of fiber purity and length, reinforcing the softness guarantee. Buyers note the result as a 't-shirt habillé' — polished yet comfortable.

Stretch recovery

4% spandex snaps back from 5-7x its relaxed length, preventing bagging.

Why this is supported

The 4% spandex in the Supima cotton jersey provides elastic recovery that allows the fabric to

stretch to 5-7 times its relaxed length and still snap backHow the stretch fabric works — elastane_recovery

, preventing the slouchy bagging typical of pure cotton tees. Additionally, the blend delivers

true two-way giveHow the stretch fabric works — two_way_stretch_vs_pure_cotton

, so the fabric moves with the body without tightening or riding up. The spandex also adds substance for a clean drape:

drape cleanly from the shoulders rather than cling or wrinkleHow the stretch fabric works — handfeel_and_drape_balance

. For buyers comparing to all-cotton tees,

it lacks the elastane stretch that keeps the Le 31 tee from losing its shape through a full dayHow the price compares to similar tees — against_uniqlo_s_supima_tee

, giving the Le 31 an edge in shape retention. To maintain this recovery over time, proper care (cold wash, low heat drying) is recommended, as elastane can lose recovery after many washes without it.

Versatility

Buyers use it as both a dressed-up and lounge T-shirt.

Why this is supported

A customer review describes it as a dressed-up T-shirt that works for smart-casual and loungewear:

Shoulder seam

Shoulder seam puckering reported on some units, causing the shirt to ruffle.

Why this is supported

One customer review describes a quality control issue with the shoulder seam:

It's causing the shirt to ruffle or rouche on the shoulder and not hang correctly Probably a quality control thing and the issue is probably related to the one shirt I bought.Customer review, September 22, 2025

This suggests the defect may be isolated, but inspecting the shoulder seam on arrival is advisable.

Color fastness

Black colourway stays darker longer than standard-cotton tees.

Why this is supported

Supima's extra-long fibers hold dye uniformly, reducing fading, and buyer reports confirm the black colourway retains its richness through extended use.

Shape retention

The 4% elastane prevents baggy elbows and collar stretching, maintaining the tailored fit over time.

Why this is supported

The 4% elastane content provides stretch recovery that prevents baggy elbows and collar stretching, a common complaint with all-cotton tees. This is supported by reviewers who note the tee maintains its tailored fit after a full day of wear.

Durability

Supima's extra-long fibers and medium-weight jersey resist pilling and thinning at high-stress areas like collar and shoulders.

Why this is supported

The Supima certification guarantees long-staple fibers that reduce pilling and are stronger than standard cotton, so the yarns resist thinning at the collar and shoulders. The medium-weight jersey adds opacity and heft that resists wear.

Care

Cold washing and low-heat drying prevent shrinkage and maintain fit.

Why this is supported

The product Q&A advises cold water washing to prevent shrinkage and tumble drying on low heat to avoid heat-caused shrinkage. Deep research confirms that the spandex blend retains stretch recovery only with these low-temperature care methods, and that gentle washing protects the Supima cotton fibers' natural pilling resistance. Together, these sources verify that this care regimen preserves the tee's intended shape and fit over repeated washes.

Fit

Medium-weight jersey with spandex falls cleanly from the shoulders without clinging, creating a dressed-up silhouette.

Why this is supported

The 96% Supima/4% spandex medium-weight jersey provides two-way stretch, allowing the fabric to drape cleanly from the shoulders without clinging. Reviewers confirm the effect:

Un T-shirt ''habillé'' très doux et qui tombe bienCustomer review, May 21, 2026

. The standard fit with fitted sleeves and Canadian design further sharpen the silhouette, and the mid-weight construction means the shirt rarely needs ironing. As one use case notes, it

.

Puckering

Shoulder seam puckering reported in isolated units disrupts the intended drape.

Why this is supported

While the majority of reviews praise the drape, at least one buyer reported a quality-control defect:

It's causing the shirt to ruffle or rouche on the shoulder and not hang correctly Probably a quality control thing and the issue is probably related to the one shirt I bought.Customer review, September 22, 2025

This isolated issue suggests buyers should inspect the shoulder seams upon purchase.

Weight and opacity

Medium-weight opaque Supima jersey suitable for layering and standalone wear.

Why this is supported

Q&A confirms the fabric is

. Deep research adds that a

medium‑weight jersey (typical of premium Supima tees in the 5.5–6 oz range) achieves the density sweet spot where opacity and drape are consistent without the bulk of a heavy teeHow the price compares to similar tees — mid_weight_versatility_and_value

, and the blend ensures the tee

. Together, these sources confirm the tee is opaque, medium-weight, and versatile for year-round wear.

Color retention

Supima fibers help black color resist fading and stay opaque.

Why this is supported

Deep research notes that

Supima’s longer fibers hold dye more uniformly and resist fading, so the black colourway will stay darker longer than a standard cotton black teeHow the price compares to similar tees — cost_per_wear_and_black_colour_retention

Price comparison

CAD 39 – roughly half the price of premium DTC tees and about $12 more than Uniqlo's Supima.

Why this is supported

Catalog compared the Le 31's CAD 39 price against three competitor brackets: Uniqlo's 100% Supima, premium DTC brands, and multi-brand retailers.

for an additional CAD 12, the Le 31 adds shape retention and slightly more tailored sleevesHow the price compares to similar tees — against_uniqlo_s_supima_tee

Against premium DTC,

the Le 31 tee delivers comparable fiber quality and a more universally accessible fit for roughly half the priceHow the price compares to similar tees — comparison_to_premium_dtc_brands

And in multi-brand retail,

a comparable certified Supima stretch tee at a multi‑brand retailer like Hudson’s Bay typically starts around CAD 60–75, so the house‑brand model delivers a tangible price advantage of roughly 35–50%How the price compares to similar tees — house_brand_economics

These comparisons confirm the CAD 39 price point occupies a distinct value position.

The CAD 39 price bypasses wholesale margins, allocating more to fiber and design. As the house brand economics analysis states:

. Compared to Uniqlo's ~CAD 27 Supima tee, this one adds elastane for shape retention:

. And versus premium DTC brands like Buck Mason and Asket, the tee delivers comparable fiber at roughly half the price:

At CAD 39, this tee offers certified Supima quality that many similarly priced competitors do not.

many ‘Pima’ tees in this price bracket are not certified and may blend in shorter‑staple generic cottonHow the price compares to similar tees — certified_supima_fiber

This durability means the tee stays presentable longer, making its cost per wear favorable.

when compared to a $15 fast‑fashion tee that fades to gray within a season, the CAD 39 upfront becomes a better economic decision over two years of regular wearHow the price compares to similar tees — cost_per_wear_and_black_colour_retention

Sizing

Sizing consistent across colors; some buyers prefer sizing up for broader shoulders.

Why this is supported

The consistent fit across colors is confirmed by a buyer who purchased multiple shades and noted they

fit perfectly to size XLCustomer review, February 16, 2026

. However, some reviewers found it necessary to size up to avoid the tailored fit causing

the shirt to ruffle or rouche on the shoulder and not hang correctlyCustomer review, September 22, 2025

. This tradeoff suggests the fit may feel restrictive to those accustomed to roomier US cuts.

Heritage

Simons' 180-year history curates the 'Designed in Canada' mark.

Why this is supported

The 'Designed in Canada' mark ties the tee to Simons' 180‑year history as a Quebec fashion institution, adding a layer of curation and quality oversight that mass‑market equivalents cannot replicate.
