Product Insights
Miiyu's dense laser-cut thong in recycled nylon offers performance parity with virgin nylon within 5–8% while saving 90% water and 80% CO2 from post-consumer waste. Its 80/20 nylon-spandex blend yields seamless laser-fused edges that resist fraying and stay flat, with a smooth, opaque fabric that maintains shape through wear. At $12 CAD, it undercuts Skims and Bare Necessities, but trade-offs include a faint waistband line under tight fabrics, no cotton gusset, and slightly reduced colorfastness.
- Environmental savings
Recycled nylon uses 90% less water, 80% less CO2, and diverts waste.
Why this is supported
Catalog verified that recycled nylon production significantly reduces resource consumption and landfill waste.
Recycled nylon uses 90% less water, emits 80% less CO2, and diverts waste from landfills and oceans.
fumaofabric.comThe recycled nylon in this thong is sourced from post-consumer materials, including
fishing nets, fabric scraps, and industrial plastic materials
materialdif.com, transforming waste into a functional undergarment.
- Performance parity
Recycled nylon matches virgin nylon in elasticity and strength within 5–8%.
Why this is supported
Catalog verified that recycled nylon performs nearly identically to virgin nylon in key mechanical properties:

- Edge quality
80/20 recycled nylon/spandex yields a clean laser-cut edge with no discoloration.
Why this is supported
The 80% recycled nylon / 20% spandex blend is rated excellent for laser-cut edge fusing:
80% Nylon / 20% Spandex | High | Excellent; yields a clean melt line with zero fiber discoloration
zaguunderwear.com.
- Laser-cut edge
Laser-cut edges are fused to resist fraying and stay flat through wear and washing.
Why this is supported
The laser thermal fusion of the 80% nylon / 20% spandex blend creates a micro-bead along the cut line that permanently locks the threads.
The precise laser heat melts the raw edge of the warp-knitted or weft-knitted synthetic fibers, bonding the yarn loops securely as the cut occurs.
zaguunderwear.comThis non-contact cutting preserves the fabric's elasticity and avoids the distortion seen with die-cutting. The resulting edge is completely flat, with no raised ridge. Customers who follow care instructions report the edges remain smooth after multiple washes.
- Value
At $12 CAD, it costs half of Skims' equivalent and undercuts Bare Necessities, using recycled nylon.

These Thongs felt nice and have a protective shield on the inside. I'm usually a small/medium in size and I bought the medium just in case and they were way too small for me. I would have to buy a large, I never had to buy large before.
Fit is perfect!
Other than the colour being a little too dark compared to what I expected, these thong undies are easy to wear and easy care. I'm happy I bought several pairs!
