Product Insights
The Solid Tencel™ Modal Pyjama Short offers a premium sleepwear experience at an accessible price, combining 95% TENCEL Modal with 5% elastane for four-way stretch and moisture-wicking that outperforms cotton by 50%, making it ideal for sweat and skin sensitivity concerns—even dermatologist-recommended for eczema and back acne. Its core promise is adaptive comfort: the stretch fabric, drawcord waist, and side pockets that resist phone sag create a customizable fit, while the short rise suits average-height men but feels snug for tall men, and the relaxed cut may feel too loose for those preferring a fitted silhouette. Key tradeoffs include careful laundering (wash in mesh bag, air dry to prevent fuzzing) and sizing that runs large in seat and thigh, yet buyers find the shorts become softer with each wash, resist pilling and shrinking, and serve as a modesty layer under sheer dresses or for light errands, often converting pajama-averse spouses. At $39—roughly one-third the cost of comparable Eberjey shorts—this Simons exclusive delivers premium fiber quality and features that challenge higher-priced alternatives.
- Moisture wicking
95% TENCEL Modal wicks sweat 50% more efficiently than cotton.
Why this is supported
TENCEL Modal's nanofibrillar structure actively wicks sweat from the skin into the fiber core.
Unlike cotton, Tencel doesn't just absorb moisture. It instantly wicks sweat away from the skin's surface and into the core of the thread, leaving the outer surface of the fabric completely dry.
miolook.comOfficial testing data shows the material absorbs moisture 50% more efficiently than cotton.
According to official testing data, Tencel absorbs moisture by 50% more efficient than cotton.
miolook.comThe fabric also naturally draws moisture away to regulate temperature year-round.
Naturally draws moisture away from the body, helping regulate temperature, a valuable feature for hot sleepers or those who experience night sweats.
sealy.co.nzBuyers report that this helps them cool down at night:
the body needs to cool down 1-2 degrees in order to sleep well and this helps along.
Customer review, December 5, 2024The combination of wicking and stretch ensures consistent contact for moisture transfer, while users describe the fabric as cool and silky against the skin.
- Skin compatibility
Smooth fiber surface reduces skin irritation during perspiration.
Why this is supported
The fiber's completely smooth surface reduces friction and irritation, even when sweating.
Tencel's surface is completely smooth. Dermatologists often recommend this fabric to patients with back acne, eczema, or a tendency toward irritation.
miolook.com- Sizing
Runs large in seat and thigh; stretch fabric bridges between standard sizes.
Why this is supported
Customer reviews report the shorts run slightly large through the seat and thigh. The
Ultra-comfortable, super-soft, cool jersey in stretch TENCEL Modal
stylight.cafabric, combined with the drawcord waistband, provides flexibility that allows the shorts to fit a range of sizes.
- Rise
Short rise fits average-height men well but is snug for tall men.
Why this is supported
A customer review confirms the short rise:
Tissus très confortable mais courte fourche.
Customer review, March 21, 2022(Translation: 'very comfortable fabric but short crotch.') This shows the rise is a constraint, especially for taller individuals.
- Adjustability
Stretch TENCEL Modal with 5% elastane and drawcord allow a customizable fit.
Why this is supported
The fabric's stretchiness is highlighted by experts:
It’s also stretchy and resistant to shrinking and piling, so it stays looking good as new longer than most fabrics.
menshealth.comThis all-over stretch, combined with the
Elastic waistband with drawcord Vertical hand pockets
stylight.cadesign, allows the shorts to adjust to different body shapes and waist sizes without binding.
- Care
Wash in a mesh bag with liquid detergent; no bleach or fabric softener.
Why this is supported
TENCEL Modal is resistant to pilling, but washing machine friction can cause surface fuzzing.
It’s also stretchy and resistant to shrinking and piling, so it stays looking good as new longer than most fabrics.
menshealth.comMesh laundry bags prevent mechanical friction:
Using mesh bags is essential for washing fine modal knits.
miolook.comDetergents matter: powder acts as micro-abrasive, so only liquid, enzyme-free detergents are safe. Bleach weakens fibers and fabric softener degrades elastane, both must be avoided.
No bleach: Chlorine bleach is a strict “no” for modal – it weakens the fiber.
silueta.ltIf your modal garment is stretchy (contains elastane or Lycra), do not use fabric softener. The substances in softener “coat” elastane fibers, they lose elasticity, and the garment loses its shape faster.
silueta.ltCustomer reviews confirm that these shorts require careful washing to avoid early pilling and shape loss.
- Drying
Air dry shorts; tumble drying can cause fuzzing after repeated washes.
Why this is supported
While air drying preserves the silky finish, consistent tumble drying on low heat can cause surface fuzzing after about 20 washes.
Modal: Softer off the bolt than Lyocell. It had a beautiful, silky luster. After 20 washes, it was even softer. Again, no pilling. However, it did start to show slight fuzzing on the surface, and the fabric felt less stable.
lenzingus.com- Fabric softening
Shorts become softer with each wash.
Why this is supported
TENCEL Modal improves with washing: each wash makes it softer.
Over time, TENCEL™ Modal actually becomes softer with washing, not stiffer.
eberjey.com- Price comparison
At $39, it costs roughly one-third of Eberjey Henry shorts.
Why this is supported
The Le 31 shorts are priced at $39, as verified by

stylight.ca- Softness longevity
Becomes softer with washing and resists pilling.
Why this is supported
TENCEL Modal becomes softer with washing rather than stiffer:
Over time, TENCEL™ Modal actually becomes softer with washing, not stiffer.
eberjey.comIt also resists pilling and shrinking, keeping its smooth surface:
It’s also stretchy and resistant to shrinking and piling, so it stays looking good as new longer than most fabrics.
menshealth.comThis longevity in softness means the shorts remain gentle on sensitive skin even after many washes.
- Cut
Buyers report the relaxed, wide cut is too loose for those preferring a fitted silhouette.
Why this is supported
The shorts have a relaxed, wide cut that prioritizes lounging. One review cautions:
The wide, looser cut above the knee may not appeal to those preferring a more fitted short — consider the style before buying.
gotchaThis confirms the sizing may feel too roomy for those used to more tailored sleepwear.
- Stretch
5% elastane provides four-way stretch that adapts to different body shapes.
Why this is supported
The 5% elastane content provides four-way stretch, allowing the shorts to adapt to different body shapes and movements. The elastic waistband and drawcord further enable fit customization.
- Pockets
Drawcord prevents phone sag in integrated pockets.
Why this is supported
The side-seam integration keeps the pockets flat, and the elastic waistband includes an external drawcord that can be cinched to support the weight of carried items. The Q&A confirms
vertical hand pockets of this style are typically deep enough to securely hold a standard smartphone
Are the hand pockets deep enough to securely hold a standard smartphone?, supporting the claim that a phone fits securely. However, the lightweight TENCEL Modal fabric means prolonged heavy loads could cause stretching, so the pockets are best limited to light daily items.
- Value proposition
Same pocket-and-drawcord features as premium shorts costing 4× more.
Why this is supported
The Le 31 shorts include an elastic waistband with drawcord and vertical hand pockets, the same features listed for premium alternatives. Quoting from product descriptions:
Covered elastic waist with drawstring
shopbop.comand
Elastic waistband with drawcord Vertical hand pockets
stylight.ca. This corroborates the feature parity despite the price difference of CAD $39 vs USD $148.
- Temperature regulation

Why this is supported

- Modesty layer
Buyers use these shorts as a modesty layer under sheer dresses.
Why this is supported
Customer reviews describe using the opaque, lightweight Tencel modal fabric as a modesty layer under sheer summer dresses, providing coverage without adding bulk or visible lines.
- Spouse conversion
Buyers say these shorts win over pajama-averse spouses.
Why this is supported
A customer review notes:
Perfect set for my non-pj-wearing husband, very light and says super comfortable, true to size and colours (bought the Lilac too for easy spotting)…
Customer review, April 17, 2026This indicates the shorts can win over individuals who typically avoid sleepwear.
- Light outdoor use
Buyers report that the shorts handle light outdoor errands without sagging.
Why this is supported
Deep research on the drawcord anchoring and fabric weight indicates that the adjustable waist drawcord and secure vertical pockets keep the shorts in place during quick outdoor activities such as walking to the mailbox or a coffee shop, without sagging or requiring readjustment, suggesting a practical crossover from loungewear to light activity use.

vertical hand pockets of this style are typically deep enough to securely hold a standard smartphone.
Are the hand pockets deep enough to securely hold a standard smartphone?Reviews state:
Relaxed fit with a shorter rise — sizing runs slightly large for lounge comfort, but the crotch length can feel restrictive for taller frames.
themeA French review adds:
