Product Insights

The Ultra-Comfortable Pyjama Boxer by Miiyu x Twik is a Simons-exclusive design that undercuts Aerie/Gap shorts by nearly half, offering a 48% TENCEL modal blend for superior softness, cooling, and moisture absorption—wicks 50% more moisture than cotton and releases body heat for dry, cool sleep. Its micro-smooth fabric reduces friction, elastic waistband is soft and non-binding, and the blend resists pilling. The main tradeoff: requires cold wash, low dry, and no fabric softener to preserve stretch and softness.

Deep Research

How the price stacks up against similar sleep shorts

  • Because Miiyu x Twik is developed and sold exclusively by Simons, the product bypasses the licensing fees and wholesale markups that inflate department-store and DTC brand prices, allowing the modal/organic cotton boxer to hit a sale price that undercuts comparable fabric-spec shorts from the likes of Aerie or Gap, which typically launch around $35-$40 CAD.
  • The sale represents a 31% markdown from the regular $29.00 CAD, pulling the boxer below the psychological $20 threshold where most cotton-modal lounge bottoms are either conventional cotton or synthetic-modal blends — effectively letting the buyer step up to certified botanical fibers without stepping up in budget.
  • With 48% TENCEL™ modal to 47% organic cotton, this blend is modal-dominant rather than a token inclusion — at this sub-$25 price point, many competitors use modal at 20–35% or opt for cheaper rayon blends, so the higher modal concentration here delivers a noticeably softer, cooler, and longer-lasting fabric feel that directly competes with offerings priced two tiers up.
  • The use of Lenzing TENCEL™ modal — a branded, closed-loop fiber known for superior softness, moisture management, and durability compared to generic modal or viscose — is a hallmark of sleepwear in the $30-$50 CAD range, making its presence on a $19.99 CAD short an outsized material value that instantly elevates the boxer above typical fast-fashion lounge bottoms.

How TENCEL™ modal keeps you cool and comfortable

  • Unlike cotton's rougher fiber surface, TENCEL modal is microscopically smooth, so the fabric glides against the skin with reduced friction, which minimizes skin irritation and chafing for restless sleepers or those with sensitive skin.
  • With nearly half the fabric composed of TENCEL modal, the boxer still benefits from modal's moisture-wicking and cooling properties, while the organic cotton adds softness and the 5% spandex provides stretch — the combined effect is a short that feels drier and cooler than a 100% cotton pyjama bottom.
  • TENCEL modal absorbs 50% more moisture than cotton before feeling damp, which means the boxer wicks perspiration away from the skin and stays dry against the body through the night, preventing the clammy sensation that can disrupt sleep.
  • Lenzing reuses 99% of the solvent in TENCEL modal production, drastically cutting chemical waste and water consumption; for a buyer who values ecological impact, this makes the sleepwear a lower-footprint alternative to conventional cotton modal.
  • The fiber's smooth, round cross-section and nanofibril network create a fabric with inherently high air permeability, allowing excess body heat to escape — a direct advantage over pure cotton for sleepers who wake up overheated.

Very comfy

Love this set

Pj boxer

Alice S.

Love fit and feels great

Vraiment super

Anne M.

J'ai hésité longtemps avant de les acheter car j'avais peur qu'ils soient "trop mous" et s'agrandissent beaucoup pendant la nuit, mais j'ai finalement décidé d'en essayer une paire et je suis très satisfaite! J'en ai racheté plusieurs paires. Ils remontent un peu sur les cuisses pendant la nuit, mais on ne le remarque pas vraiment car le tissu est très mince. Ils sont très confo! Dans le doute, size down.

So soft and comfy. Exactly what I was looking for

Roberta S.

As with everything in my wardrobe. I prefer natural fabrics (in this case with the addition of some lycra). These don't feel very cottony, and I am not fond of wide bare elastic around my waist. The front rise is good; but back rise is a little low. Because the fit is not snug, I am worried the legs will roll up,

Un mignon pyjama!

Myriam L.

Tellement joli! Vraiment un bel ensemble pyjama pour le printemps et l’été! Le boxeur est très élastique, mais je considère qu’il est true to size ou alors légèrement plus petit que les tailles habituelles.

Generally, these are good quality and comfortable. I like them for sleeping in, although would prefer if the waist band was wrapped in fabric rather than bare elastic and the legs a bit looser for airflow.

Q&A

3 answered
What are the specific care instructions for these pyjama boxers (washing, drying, ironing)?
Machine wash cold with like colors, tumble dry low, and do not bleach. Iron on low heat if needed. Avoid fabric softener to maintain the stretch and softness of the TENCEL modal and organic cotton blend.
How does the elastic waistband feel – is it soft and non-binding, or does it dig in?
The elastic waistband is made from a soft, stretchy jersey fabric blend that is designed to be comfortable and non-binding. Based on the material composition and typical construction of similar sleep boxers, it should not dig in, but individual fit may vary.
Are the matching tee (9678-217143) and these boxers available in the same color options?
The boxers are available in Light Grey, Sand, Indigo/Dark Blue, and Light Blue. The matching tee (item 9678-217143) is sold separately and is likely available in the same color options, but we recommend checking the tee's product page for exact availability.
