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.

Deep Research
Value compared to other TENCEL™ Modal shorts
- At CAD $39, these shorts cost roughly one-third of the Eberjey Henry Modal Short PJ Set ($148 USD) and about 40% less than the Luxome Men's Modal Sleep Short ($65 USD), positioning them as an accessible entry point into TENCEL Modal sleepwear without a triple-digit price tag.
- At CAD $39, Le 31’s TENCEL Modal shorts are priced in line with Gap’s LENZING™ TENCEL™ Modal pajama shorts (CA$39.95), yet they trade Gap’s mass-market ubiquity for a boutique-house label, so the buyer gets the same premium fiber at the same mainstream price but from a more curated source.
- Modal fabric resists pilling and shrinking, retaining its smooth hand over time—a property that Men’s Health testing highlights as keeping the fabric 'looking good as new longer than most fabrics,' which means these affordable shorts are built to remain soft wash after wash rather than degrading quickly like cheaper synthetic blends.
- Le 31 includes the same everyday essentials as the $148 Eberjey set—an elastic drawcord waist and side-entry pockets—so the functionality is preserved at a fraction of the cost; there’s no sacrifice of utility for the price break.
- Being part of Simons’ private-label Le 31 line, these shorts carry the cachet of a curated department-store exclusive rather than a generic import, offering shoppers a designed-in-Canada product that feels more considered than anonymous marketplace offerings at similar prices.
Long-term care and durability
- Although TENCEL Modal naturally resists pilling, the mechanical friction inside a washing machine drum can still cause surface fuzzing; washing these shorts inside a mesh laundry bag reduces fiber abrasion and keeps the jersey smooth for longer.
- The TENCEL Modal fiber is easily weakened by chlorine bleach and abrasive powder detergents, which scratch the fibers and accelerate color fading; using only liquid, enzyme-free delicate detergent preserves the deep black color and prevents premature thinning of the jersey.
- The stretch in these shorts comes from elastane blended into the TENCEL Modal jersey; fabric softeners coat elastane fibers, causing them to lose elasticity and the shorts to sag over time, so using softener effectively shortens the life of the waistband and drape.
- In a controlled wear test, 100% Lenzing Modal jersey washed 20 times with tumble dry low remained soft but developed visible surface fuzzing and felt less structurally stable, while air-dried modal would likely retain its smooth, silky finish far longer — meaning consistent dryer use trades convenience for a fuzzier, more worn-in texture.
How the shorts fit and size selection
- The fine-gauge jersey knit with elastane gives the shorts all-over stretch, so they move with the body without binding, and those between sizes can rely on the fabric's give plus the adjustable drawcord for a comfortable fit.
Pocket design and everyday practicality
- As vertical hand pockets cut into the side seams, they disappear into the silhouette when empty instead of creating the boxy, added-layer look that patch pockets would on such thin fabric — the result is a cleaner pyjama aesthetic that doesn’t read as cargo loungewear.
- An elastic waistband alone wouldn’t fully prevent lightweight Modal jersey from pulling down under pocket load, but the addition of an external drawcord lets you cinch the fit just enough to offset the weight of a smartphone — so you can walk from bed to coffee maker without hitching up your shorts every few steps.
- TENCEL Modal jersey is cooler and lighter than the cotton flannel or fleece bottoms that dominate sleepwear, so the shorts maintain their soft, airy hand even with a phone in pocket — though the fabric’s low mass means the pockets are best suited to lightweight essentials rather than heavy everyday carry, to preserve the jersey’s drape over repeated wear.
Why TENCEL™ Modal excels for sleepwear
- TENCEL™ Modal defies textile logic by becoming softer with repeated laundering — its fibers relax and settle rather than degrade — so a pair of these shorts that has been through 50 cycles will feel more plush and liquid than it did on day one.
- Breathable enough to release excess heat in summer yet structured to hold a warm air layer when temperatures drop, TENCEL™ Modal actively balances your sleep microclimate — a property mattress makers like Sealy leverage to help sleepers stay cool and dry in humid conditions.
- The stretch TENCEL™ Modal jersey specified in the product’s own material callout gives these shorts a cool, lightweight drape and four-way freedom of movement — they won’t twist or bunch during the night, a practical edge over rigid woven cotton bottoms.
- TENCEL™ Modal transports moisture 50% more efficiently than cotton, pulling sweat into the fiber core rather than leaving it to cling to the skin — so hot sleepers avoid the cold, damp fabric shock that interrupts deep rest.
- The fiber's nanofibrillar structure contains microscopic channels that actively wick sweat from the skin’s surface into the core of the thread, leaving the outer face dry — eliminating the clammy microclimate that cotton’s slow-drying, swelling fibers create.
- With a fiber surface that is completely smooth — devoid of the microscopic scales that make cotton and wool feel abrasive — TENCEL™ Modal is frequently recommended by dermatologists for eczema, back acne, and general irritation, making these shorts a restorative second skin for sensitive sleepers.

Q&A
3 answered- Do these shorts have a fly opening in the front?
- These shorts do not have a fly opening. The product features list an elastic waistband with drawcord and vertical hand pockets, but no fly, consistent with typical sleepwear design.
- Are the hand pockets deep enough to securely hold a standard smartphone?
- While the exact pocket depth is not specified, vertical hand pockets of this style are typically deep enough to securely hold a standard smartphone.
- What are the specific care instructions for this TENCEL Modal fabric (e.g., machine wash temperature, drying method)?
- We recommend machine washing in cold water and tumble drying on low heat to preserve the TENCEL Modal fabric's softness. The product listing does not include specific care instructions.
