Product Insights
Miiyu's Stretch Microfibre High-Waist Thong, the in-house Simons label designed in Canada by a retailer trading since 1840, sits at 12 CAD flat across all 30 variants — six colours in five sizes, X-SMALL through X-LARGE, with no upcharge for X-Large or print, working out to about $7.99 per pair in the 5-for-$39.95 set. The core promise is a soft, abrasion-resistant recycled nylon microfibre body with a high waist that anchors above the hip bone without tight elastic and, in Black and Light Beige, reads as undetectable under fitted clothes, paired with a 100% cotton gusset that maintains the 3.8-4.5 acidic pH of healthy intimate skin, wicks moisture, and meets ACOG cotton-lining guidance — a combination few thongs at this price include. The material story is the differentiator and the constraint: recycled post-consumer nylon (fishing nets among the feedstock) cuts water use 90% and CO2 80% versus virgin, and yarn costs 20-40% more, yet the price holds. The tradeoff is durability and consistency of fit rather than comfort on contact: buyers report the back seam feels invisible at first then irritates within hours, the recycled fabric loosens by day's end and shrinks more in the wash than virgin nylon, stretch recovery is lower so the band can go slack by evening, and the same labelled size fits differently between colourways — size up when between sizes. The cotton gusset that makes all-day wear viable is also what caps the product: built for daily use, not high-intensity workouts, where it holds sweat, and the recycled content does not stop microfibre shedding in the wash.
Verified claims
- All-day comfort
- Buyers report the back seam feels invisible at first, then irritates within hours and loses stretch by day's end
- Size consistency
- The same labelled size fits differently between colourways and shrinks across washes.
- Abrasion resistance
- The polyamide microfibre resists abrasion at the inner thigh and gusset edge.
- Sizing
- Buyers report the same size fits smaller in some colours; size up when between sizes.
- Fit retention
- The recycled microfibre loosens by day's end and shrinks more in the wash than virgin nylon.
- Hygiene
- The 100% cotton gusset maintains the 3.8-4.5 acidic pH of healthy intimate skin.
- Breathability
- The 100% cotton gusset wicks moisture off skin, keeping all-day wear viable.
- Workout suitability
- Built for daily wear, not high-intensity workouts, where cotton traps sweat.
- Waistband
- The high waist anchors above the hip bone and holds position without tight elastic.
- Stretch retention
- Buyers report the stretch gives out by day's end, and the recycled band can relax over time.
- Stretch recovery
- Recycled nylon recovers less stretch than virgin nylon and can go slack by evening
- Microfibre shedding
- Recycled content does not stop microfibre shedding in the wash
- Material cost
- The in-house Simons label keeps this recycled-nylon thong at 12 CAD because Simons owns the brand, design and margin end-to-end rather than paying a third-party wholesale markup.
- Workout use
- Cotton gusset holds sweat, so it suits daily wear, not high-intensity training
- Provenance
- Miiyu is Simons' own in-house label, designed in Canada by Simons, a Canadian retailer trading since 1840.
- Flat pricing
- All 30 colour-and-size combinations share one 12 CAD price, with no upcharge for X-Large or the Flowers print; buying through the 5-for-$39.95 offer works out to about 7.99 CAD per pair.
- Value
- At about $7.99/pair, few thongs include a cotton gusset.
- Size availability
- All 30 variants — six colours across five sizes — run the full X-SMALL to X-LARGE span at one flat price.
- Fabric recovery
- Recycled polyamide microfibre has lower stretch recovery, so the high-waist band can loosen over wear.
- Environmental footprint
- The recycled nylon body is made from diverted textile waste — post-industrial spinning scraps, offcuts and yarn trimmings, or post-consumer waste such as fishing nets, carpets and discarded apparel — so the recycled label is about diverting waste from landfill rather than a specific ocean-plastic claim.
- Material quality
- The body is a soft, stretchy recycled nylon microfibre made from 80% recycled nylon and 20% spandex, and the 100% cotton gusset adds breathability for all-day wear.
- Gusset
- 100% cotton gusset wicks moisture and meets ACOG cotton-lining guidance.
- No-show
- Buyers report the lightweight microfibre body is largely undetectable under clothes because the thong cut removes rear fabric, but the high waistband can still show under very fitted or low-rise garments and a faint side edge may show under very thin, tight fabrics.
- Colourways
- Only Black and Light Beige disappear under clothes; the other shades read as colour
- Care
- Wash cold on a delicate cycle and air-dry; skip fabric softener and dryer sheets, and use a mesh lingerie bag to protect the microfibre from snags.
- Opacity
- The Black microfibre is a dense, opaque knit that should not show through under leggings or light trousers, but Light Beige — and to a lesser degree Blue/Green — is more likely to read through very thin or light fabric.
- Waistband rise
- The high waist sits around the natural waist — at or just below the belly button for most people — rather than a true over-the-belly-button cut.

Go-to daily thong
Some customers reach for this soft microfibre thong as a daily staple for work or being on the go, valuing its comfortable, elegant fabric. Others report the back seam can become irritating after a few hours of wear, especially for those sensitive to seams, and that the fabric loses stretch by the end of the day, leading to a less supportive fit.[1]
Product comparison
Compared within this brand.
| Stretch Microfibre High-Waist Thong Recycled Nylon: Choose this if you want a high-waist microfibre thong for everyday rotation: some customers use it as a go-to daily style and praise the soft fabric, wide waistband, and bonded leg edges, with a 100% cotton gusset. Some reviewers report the back seam can irritate after a few hours and that the fabric loses stretch by the end of the day. Note that sizing can vary between colors, so an identical pair in a different shade may fit noticeably smaller.[1,2,3,4] | Stretch Laser-Cut High-Waist Thong Recycled Nylon: Choose this if you want a high-waist thong with laser-cut, seamless-looking edges and a smooth matte knit for an invisible look under clothing. Note that reviewers say the fit runs small, so sizing up is recommended for everyday comfort, and the slippery fabric has been reported to roll down during high-movement days, creating a visible bulge that defeats the no-show look. Also be aware that liners reportedly detached on 7 of 10 pairs after a single wear and cold wash, leaving them unwearable.[5,6] | Ultra-Soft Stretch High-Cut Thong Recycled Nylon: Choose this if you want a high-cut thong that sits high on the hip, made from ultra-soft stretch microfibre in a recycled nylon blend (75% reprocessed nylon, 25% spandex) with a 100% cotton lining, a stretch waistband, and stitched edges. It comes in four colors—Mint/Pistachio Green, Blue, Indigo/Dark Blue, and Peach—each listed in five sizes from X-Small to X-Large, and one shopper describes really loving the Miiyu line from Simons, a personal preference in a thread about affordable quality underwear.[7,8,9,10] |

Parfait
J’adore
Comfortable
Ce sous vêtement est exactement ce que je cherchais. Confortable et élégant et le tissu est parfait.
Who decided on that seam placement?
At first blush, these seem great: lightweight, undetectable under clothes, and stretchy. But after just a few hours' wear, you'll realize the seam down the back is really irritating and by the end of the day, there's no stretch left. I wanted to love them, but nope.
Thong panties
I haven’t worn them yet. But these blue ones are okay for fit, the other ones exactly the same different color seem smaller
