Why TENCEL modal makes a better nightgown

• The knit is inherently temperature-regulating, adapting to body heat fluctuations to stave off both overheating and chills through the night, which makes the nightie seasonless in a way that cotton sleepwear — which tends to hold moisture and feel clammy — often is not.
• TENCEL Modal fibers actively pull moisture away from the skin and release it into the air far more efficiently than standard cotton, maintaining a drier, less clammy microclimate — a direct sleep-quality upgrade for anyone who tends to overheat or sweat at night.
• The nightie uses TENCEL™ Modal from Lenzing, the Austrian fiber innovator that has been refining sustainable wood-based textile production since 1938; the fiber carries a fully traceable chain of custody from FSC/PEFC-certified European beech forests through a closed-loop manufacturing process that recaptures over 95% of water and solvents, giving the Miiyu nightie a level of documented eco-responsibility that generic modal or viscose cannot match.
• TENCEL Modal naturally resists pilling and holds its dye saturation through repeated machine cycles, so the black colourway stays deep and the fabric stays smooth rather than fading to grey or developing raised pills — a longevity advantage over standard cotton or rayon sleepwear that can look tired after a season.
• The beech-derived filaments are exceptionally long and smooth, so the fabric surface has very few rough fiber ends to catch on skin, and unlike cotton the hand feel actually deepens over time — the fibers relax and settle with washing rather than stiffening, keeping the nightie at peak softness for years.

TENCEL modal's environmental edge

• TENCEL modal production uses up to 95% less water than conventional cotton (130 liters vs 2,700 liters per 180g), making this nightie a dramatically less water-intensive choice in a category where cotton dominates.
• The wood pulp used to make the modal is FSC-certified, guaranteeing it comes from responsibly managed forests rather than from deforestation or pesticide-intensive cotton farming.
• On a garment-weight basis, TENCEL modal emits 2.1 kg CO2 versus 5.5 kg for conventional cotton — a 62% reduction — so choosing this nightie over a cotton equivalent shaves more than half the climate impact from the sleepwear drawer.
• Unlike synthetic sleepwear, TENCEL modal fibers shed during washing biodegrade within months, eliminating the microplastic legacy that polyester leaves in waterways with every laundry cycle.
• TENCEL modal is manufactured in a closed-loop system that recovers over 99% of the solvent, drastically cutting chemical waste and emissions relative to conventional viscose — the nightie's fiber thus arrives with a markedly cleaner production backstory.
• Lenzing's TENCEL modal is certified biodegradable and compostable by TÜV Austria, so the nightie will naturally decompose at end of life instead of contributing to the synthetic textile waste burden in landfills.
• A 2010 lifecycle assessment published in Resources, Conservation and Recycling ranked TENCEL and Modal as having the lowest overall environmental impact among all major apparel fibers, corroborating Lenzing's eco-claims with independent academic research.
