Product Insights

Le 31's Fluid Tencel™ Modal Pyjama Pant offers a relaxed, fluid cut with an elastic waistband and drawcord for adjustable tension, using 4-way stretch TENCEL modal and elastane to prevent binding and maintain shape through wear and washing. The fabric softens over time, becoming a favorite with each wash, and wicks moisture 50% more efficiently than cotton for drier sleep. Sustainability is central: TENCEL Modal uses 10-20 times less water than cotton and holds EU Ecolabel and other certifications. The main tradeoff is that air drying is recommended to preserve the relaxed fit and prevent shrinkage, extending the garment's life and lowering cost-per-wear and environmental impact.

Verified claims

Waist fit
Elastic waistband and drawcord adjust tension from snug to relaxed.
Relaxed fit
Fluid cut and smooth fabric prevent binding for free movement through seat and thigh.
Shape retention
Elastane blend returns to shape after wash, preventing sagging over time.
Fit maintenance
Air drying is recommended to prevent shrinkage and maintain relaxed fit.
Waist adjustability
The drawcord lets one size accommodate a wider waist range, so most wearers can buy their usual size instead of sizing up for waist room.
Long-term value
Long-term owners report wearing the pants for years and buying multiple pairs, supporting a lower cost per wear.
Softness
The fabric becomes softer with washing and resists pilling, maintaining its smooth feel with proper care.
Fit and drape
4-way stretch and fluid drape allow the pants to move without binding or clinging.
Moisture wicking
Wicks moisture 50% more efficiently than cotton and regulates temperature for drier sleep.
Stretch and fit
95% TENCEL modal, 5% elastane: four-way stretch and shape recovery with a relaxed cut that fits various body shapes without sizing up.
Care
Gentle washing and air drying preserve fit and softness.
Durability
Fabric softens with washing and returns to shape after wear; air drying prevents shrinkage.
Sustainability certifications
TENCEL Modal fiber holds EU Ecolabel, CanopyStyle Dark Green Shirt, and TÜV Austria biodegradable certifications.
Environmental impact
Uses 10-20 times less water than cotton, with FSC and EU Ecolabel certification.
Pocket function
The pants have a pocket that is strong enough to hold a large phone, according to a buyer who uses it that way.
Drawcord design
The waist drawcord is flat and resists knotting beyond repair, so the tie stays manageable with repeated wear.
Fabric weight and season
Buyers describe the fabric as lightweight, breathable, and thin, with several saying it is best for summer and not a winter pajama.
Fit sizing and length
Buyers find the pants true to size overall, but the inseam runs long: one 6-foot wearer found them too long, while others appreciate the extra length.

Glen W.

Very comfortable and they seem durable. Well worth the price. My only complaint -- it's more of a minor annoyance -- is that they ride up to my calf during the night. Consider choosing one size larger in the matching shirt but the pants are true to size.

Very comfortable pants for lounging

Arvie K.

These are great pants, very comfortable and not too thin. The drawstring is runs around the waste and ties firmly allowing the pant pocket to take the weight of a large screen phone. The drawstring is visible on the outside of the waste (not hidden). The blue colour is a medium blue.

Very soft!

Perfect for lazy days, they are so soft. Had my last pair for 6 years.
