How the organic cotton and TENCEL modal blend feels

• TENCEL™ modal fibers are finer and more uniform than cotton, giving the pant a silky, low-friction surface that drapes more fluidly than standard cotton jerseys; wearers of similar TENCEL™ modal blends consistently describe the hand as 'silky-smooth' and 'luxurious', making these bottoms a tactile upgrade from basic cotton.
• The organic cotton–TENCEL™ modal blend combines cotton’s natural breathability with modal’s heightened moisture absorption and fluid drape, actively wicking perspiration away from the skin and drying faster than a 100% cotton bottom — a critical edge for hot sleepers who find pure cotton damp by morning.
• TENCEL™ modal, the Lenzing-made fiber in this blend, is inherently temperature-regulating and moisture-wicking; the fabric feels cool and smooth on contact and actively moves humidity away from the body, whereas polyester fleece traps heat and moisture.

Lettuce hem look and lasting quality

• The lettuce hem was invented by fashion designer Stephen Burrows in the 1970s, created by stretching knit fabric while stitching a dense zig-zag or overlock edge to produce a permanent wavy finish — on these pajama pants that means the decorative edge carries a direct lineage to a disco-era technique originally celebrated for adding movement to garments, giving the loungewear a subtle fashion-history reference and an intentional design lift over a basic straight hem.
• Lettuce hems are sewn exclusively on knit fabrics — here an organic cotton/TENCEL modal rib — and because knits do not unravel the way wovens do, the hem naturally resists fraying even without additional finishing; the dense overlock stitching further locks the raw edge, so the decorative waves stay intact through repeated washes without developing loose threads.
• The rippled texture of a lettuce hem benefits from a gentle wash cycle and avoidance of high-heat drying to prevent the stretched stitches from gradually relaxing; the organic cotton/modal blend’s natural resilience helps the edge bounce back, but treating the pants as a delicate item extends how long the ruffles stay crisp and distinct.
• Unlike a traditional hem that folds the fabric under to create a stitched edge, a lettuce hem is sewn directly along the raw fabric edge without any turn-up, so the pant cuff remains exactly as thin and soft as the rest of the leg — eliminating the rigid double-layer ridge that can press into the skin during sleep and making the hem virtually undetectable against the ankle.
• A lettuce hem depends on the knit fabric having sufficient stretch and recovery to hold its ruffles over time — this pant’s ribbed organic cotton/modal blend is lightweight and inherently elastic enough to spring back, so the rippled edge stays defined wear after wear rather than relaxing into a limp, half-formed curl the way a heavier or low-recovery knit might.

Ribbed weave stretch and texture

• The alternating knit/purl construction inherent to ribbed fabric delivers superior elasticity and shape retention in both directions — these pants are engineered to bounce back to their original silhouette after a full night's wear, avoiding the dreaded baggy knees that plague conventional jersey pj bottoms.
• The TENCEL modal in the blend imparts a silky, ultra-soft hand and natural drape — similar to how premium modal sleepwear from brands like Eberjey achieves its buttery feel — meaning these pants will glide over the legs rather than cling, while staying breathable for warmer nights.

Matching tees and cami in the collection

• The cami sold separately as the other matching top follows the babydoll template seen in the Miiyu x Twik sleep sets: a cropped fit with thin straps, a front bow, and the same lettuce-edge hem, transforming the pant into a soft, romantic pyjama silhouette when worn together.
• The coordinating short-sleeve tee—explicitly cross-referenced with this pant on the Miiyu Mini listing and sharing the same ribbed organic cotton–TENCEL modal blend—has a fitted, crew-neck silhouette that creates a streamlined, matched-texture loungewear set when paired with the pant; the Pink colorway is confirmed to extend across both pieces, making it easy to buy the complete look in the same shade.

How the $39 price compares to similar pants

• Mavi sells a Tencel-blend lounge pant (49% Tencel™, 44% polyester, 7% elastane) at a full retail of $88 CAD, occasionally discounting it to as low as $44 CAD, yet even that sale price sits 13% above the Miiyu x Twik pant’s steady $39 CAD while using polyester instead of organic cotton—so the Simons pant delivers a more premium fiber mix at a lower absolute cost.
• Londre’s lounge pant (93% modal, 7% spandex) is priced at $128 CAD regular, with sale events dropping it to $102 CAD; at $39 CAD the Miiyu x Twik pant comes in at less than one-third the regular cost for a very similar ribbed modal base—a difference that positions it as a clear budget-channel alternative to premium DTC modal loungewear.
• ROWE’s two-piece set made from 90% Tencel Modal and 10% spandex retails for $92 CAD, implying a per-piece cost of around $46; the Miiyu x Twik pant at $39 CAD undercuts that implied price while offering the flexibility to mix sizes by purchasing the matching cami or tee separately, making a fitted head-to-toe lounge look more economical than a fixed-size set.
• When The Good Trade rounded up organic pajama brands, affordable-tier labels like Pact started at $28 USD for a bottom, while next-tier options like MATE the Label opened at $48 USD; the Miiyu x Twik pant’s $39 CAD (≈$27 USD) places it below even the entry-level sustainable loungewear floor, yet it uses a TENCEL modal blend that many eco-brands reserve for premium lines priced $50+ USD.
• Fishers Finery’s men’s pajama pant in a 55% organic cotton / 40% modal / 5% spandex jersey is listed at $40 USD (≈$57 CAD), 46% more expensive than this women’s pant despite sharing a near-identical organic cotton + modal formula; the gap reflects the cost advantage of a Simons house-brand exclusive that cuts out the wholesale margin typical of multi-brand retailers.

Sustainable sourcing of the organic cotton and TENCEL

• TENCEL™ Modal is certified biodegradable and compostable in soil, freshwater, and marine environments, so the material can break down fully at end of life instead of lingering as microplastic fibers.
• The organic cotton in the blend is grown without synthetic pesticides or fertilizers, a farming practice that underlies the GOTS standard for organic fiber; this reduces the chemical footprint of the raw material.
• Lenzing, the producer of TENCEL™ Modal, received the highest “Dark Green Shirt” ranking in the 2023 Canopy Hot Button Report for protecting ancient and endangered forests, which assures that the fiber supply chain is audited and committed to forest conservation.
• The TENCEL™ Modal fibers themselves hold the EU Ecolabel for textile products (license AT/016/001), a rigorous lifecycle standard that restricts hazardous chemicals and minimizes environmental impact from raw material sourcing through disposal.
• The modal manufacturing process uses a resource-efficient technology that recovers and reuses chemicals at high rates, preventing the kind of toxic wastewater discharge associated with conventional viscose production.
• The wood pulp that becomes the TENCEL™ Modal in this blend originates from forests certified to FSC® or PEFC standards or from controlled sources, which means the fiber doesn’t contribute to illegal logging or the destruction of ancient forests.
• TENCEL™ Modal fiber production emits at least 50% less carbon and consumes 50% less water than generic modal, per Higg MSI data, so the fabric’s climate and water impact is halved compared to a standard modal pajama—a substantial reduction given that the garment already uses organic cotton for its natural fiber component.
