Product Insights
Miiyu's Plain Microfibre Classic Brief offers an eco-friendly, hypoallergenic option in recycled nylon microfibre with a silky, smooth feel softer than cotton or modal, at a competitive price of $12.99 or $5.60 per unit in a 5-pack that buyers recommend. Designed in Canada to reduce import distance, it features a cotton gusset for sensitive skin but requires cold, gentle washing to prevent pilling, and its synthetic body is less breathable than all-cotton, potentially causing sweating. The secure, roll-resistant waistband and true-to-size fit adapt to body contours, and the line is also available in boyshort and lace-trim styles.
Verified claims
- Fabric feel
- Recycled nylon microfibre has a silky, smooth hand feel, substantially softer than standard nylon or cotton knit underwear.
- Value
- Designed in Canada, this $12.99 recycled-nylon brief is an eco-alternative to organic cotton; the Miiyu line is also sold at 5 for $28, or $5.60 per brief.
- Canadian design
- Simons-exclusive Canadian design lowers import distance versus US eco-brands.
- Gusset lining
- The 100% cotton lining is a gusset that requires cold, gentle wash to prevent pilling on the nylon body.
- Multi-buy
- 5-for-$28 deal cuts per-unit cost from $12.99 to $5.60.
- Community reception
- Buyers describe the 5-for-$28 deal as decent and pretty and recommend the line.
- Competitive price
- The $12.99 single price makes this one of the few recycled-synthetic briefs under $15; the 5-for-$28 pack lowers the per-unit cost to $5.60.
- Fit
- Runs true to size across the microfibre line with a secure waistband and soft microfibre that adapts to body contours.
- Durability
- Cold gentle wash and line drying prevent pilling and maintain elasticity.
- Waistband stability
- Stretch waistband resists rolling when properly sized.
- Hypoallergenic
- The recycled nylon is generally hypoallergenic, and the 100% cotton gusset can help reduce irritation; the soft microfibre is typically gentle, though the style has no specific allergy certifications.
- Range
- Recycled nylon microfibre also available in boyshort and lace-trim brief.
- Softness
- Buyers report the microfibre is soft and breathable.

| Plain Microfibre Classic Brief Recycled Nylon: Choose this if you want a high-rise classic brief with full rear coverage, made from a soft, stretch recycled nylon blend microfibre with a smooth, matte, plain finish. It has a narrow sewn waistband, bound leg openings with matching topstitching, and a central gusset panel, suiting shoppers who prefer a simple solid style without visible texture or pattern. Note that fit on the body is not shown in the available product views, and the cut is based on how the garment appears in the photographs.[1,2,3] | Lace Trim Microfibre Classic Brief Recycled Nylon: Choose this if you want a high-rise classic brief in soft, stretch recycled nylon-blend microfibre (80 percent reprocessed nylon, 20 percent spandex) with a 100 percent cotton gusset, scalloped lace trim at the waistband and leg openings, and full back coverage in a wide size range from X-Small to X-Large. Customer reviews describe the fabric as thin, lightweight, and nearly invisible under form-fitting clothes, with an accurate, forgiving fit that stays in place without digging. One review reports the leg-opening elastic stretching out quickly—especially with panty liner use—and some orders reportedly arrived in a different cut than expected, so double-check the style if full coverage matters to you.[4,5,6] | Mini-Rib Laser-Cut High-Waist Classic Brief Recycled Nylon: Choose this if you want a seamless, high-waist brief with a stretch wide waistband and laser-cut edges that leave no visible stitched hems, made from a finely ribbed recycled nylon blend (75% reprocessed nylon, 25% spandex) with a 100% cotton gusset. It suits shoppers who prefer a smooth, second-skin feel and comes in five colors (Black, Ivory/Cream Beige, Brown, Teal, and Crimson), each offered in sizes X-Small through X-Large. Note that while the edges are laser-cut and seamless, the back panel has a visible vertical center seam, so the construction is not entirely seam-free.[7,8,9] |

Miiyu line recommended as affordable and pretty
I really love the Miiyu line from Simon's. Aerie is pretty good as well, and I often have surprisingly good luck at Marshall's/Winners

Miiyu cotton/modal blend praised for softness and breathability
I swear by the miiyu line at Simon's. Specifically the cotton/modal blend that gives a great blend of softness and breathability. They are usually in stock at the Simon's in Rideau Centre. They come in a range of cuts (bikini, hipster, thong, highrise) and colours. Here's the link to the hipster: https://m.simons.ca/en/women-underwear/panties/buy-more-save-more/organic-cotton-and-modal-hipster--11003-208714?colourId=28&catId=8402
