Product Insights
Miiyu's solid ultra-comfortable elastic-waist boxer brief blends 47% organic cotton with 47% EU Ecolabel-certified TENCEL Modal—twice as soft and 50% more absorbent than cotton—plus 6% spandex for over 95% stretch recovery. The high-rise waist anchors on the natural waist, full rear coverage prevents wedgies, and the fabric wicks moisture, breathes better than cotton, and reduces ride-up friction. TENCEL Modal also soothes eczema by reducing redness, itching, and keeping skin cooler and drier. At $9.99 CAD, it costs about one-third the price of comparable premium briefs. The main tradeoff: to preserve waistband elasticity, machine wash cold, skip fabric softeners, and avoid high heat.

Confortable
disappointed
This fabric is reeeally thin and unfortunately the leg holes are really small.
As described
Very comfortable
Je ne veux plus les enlever!
Tissu très doux, coupe et longueur patfaite, même avec mes fesses bien rebondies!
Worse than before
The fabric is way thinner than it used to be - you can actually see though it! Also the front gusset used to have 2 layers of fabric and now there is just 1. No more lining in the front. I had bought these 1-2 years before and they are way better than the ones sold now. It is so disappointing that they let the newer ones be made with such poor quality. +1 star for fit, style, and material (organic cotton).
Comfortable fit
The best boy shorts yet
, je vais en acheter d'autres aujourd'hui si je le trouve
Un autre article de je vais recommander. Super comme sous vêtement. Je l'adore. Hier j'ai cherché dans sous vêtement et je n'ai rien trouvé. Désolée
Best underwear ever
Seriously the best underwear ever. The material is so soft, breathable and the fit is spot on. It's like the almost like wearing nothing feeling but with perfect fit, support and comfort. I highly recommend these. If you're new to anything with modal, you might never want to go back after trying. It is a soft, heavenly feel on your skin.
Bon produit
bonne qualité, tient bien à la taille et cuisses

Light weight and comfortable, will definitely order more.

Description conforme à la réalité
Super confortable
Great Under Shorts
Almost perfect. The white is super see through, and I was hoping for slightly thicker make. But super comfortable and great for bed and to wear under my white sheer pants or shorts.
Douillet
Belles grosses bobettes d'hiver qui gardent les "foufounes" au chaud sans rentrer dans la "craque" . . hi hi.
Very soft
I use them to sleep and they are super soft and comfy. I'll definitely buy more.
Comfortable and cute
Very comfy to wear, and the material feels nice. Thinking about getting another colour!

Super confortable ! Mais quand allez-vous recevoir ce même boxer en grandeur Large? Il n'y en a plus ds aucun magasin!
très confortable, tient bien en place
Epouse bien le corps, sans serré.
Bien
Enfin des boxer pour femme, merci. J'aurais préféré une composition majoritairement ou 100% coton bio, mais c'est un bon début. Confortable. La version en noir serre un peu les cuisses (en bas), mais la taille est parfaite. La version sable taille très bien par contre.
Confortable
Confortable, mais je préfère plus long.
A re-order
Very comfortable
Great product
Will buy more

I would recommend more of a gusset so that they are compatible with menstrual pads
Seule chez Simons sont parfaites

Je ne comprend pas la question
Excellente, maême si j'aurais préféré le boxeur noir
Will keep to see if style works for me
As with everything in my wardrobe. I prefer natural fabrics (in this case with the addition of some lycra). These are not, 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,
Confo absolue
Super sous vêtement Léger et confortable
Boy shorts
Haven’t worn them yet but wanted to see how they compared to the other boxers I purchased for the difference in price. They are shorter in the leg. They are nice but prefer the longer boxers for what I want them for.
Sous-vêtement
Très confortable !
Uneven seams
This is not well constructed, though I wanted to love it. Thighs roll up and the front seams came snagged/uneven.
Love these boxers!
Finally, underwear that doesn't ride up!

Comfy!
These are so comfortable! They’re kind of like bike shorts. They feel invisible, like you don’t have anything on, they don’t ride up your derrière, no wedgie. Super smooth!
Parfaite
Vraiment confortable!!
Pretty good
The leg did roll up a bit but mostly they fit great. Something has to change with the tags though. Tagless would be best but I’d settle for one larger tag instead of a stack of small hard fabric ones.
Love them
I really like how they fit. Very pleasant to the skin. Though material is a bit thin so I expect that I might need to replace them in a year. I’m happy that the band is not too tight on my waist
Ultra-comfortable elastic waist boy short
Elastic waist is snug. My first time buying this item. Will see how they feel post washing
Tellement confortable!
Elles sont extra confortable, le tissus est super doux, je les adore
Very comfortable and good fit,
These underwear are exceptionally comfortable and I really appreciate the healthy option they provide. The only downside is the price - otherwise, is would have been a 5-star review. Hopefully, they’ll be available soon in the "Panties on promo: 5 for $35.95” offerings.
Très confortable
Attachez votre tuque, ça part ! J'ai acheté ça parce qu'il fait froid et que je voulais vivre un peu de confort. Tissu très doux, élastique. Je ne vivrais que dans ça. J'ai presque hâte à faire du lavage pour les remettre plus vite.

Thin and silky, comfortable and looks good on. I’m 5’4 and 140lbs. 29 waist 38 hip and bought a medium. I will say that the legs look longer in photo but on me they are a bit shorter and I am happy with that
