Our Seamless Series is the hottest trend of 2026! With irritation-free, seamless construction, enjoy all-day smooth comfort. Breathable, moisture-wicking fabric keeps you cool and confident anywhere.Pro Tip: Always check the crotch lining material—mulberry silk-lined gussets provide pH-balancing properties comparable to medical-grade textiles, ensuring optimal hygiene and comfort.
⚠️ Critical: Avoid non-Oeko-Tex certified synthetics—cheap polyester blends trap heat and moisture, increasing the risk of UTIs by 37% in clinical studies.

Sino Finetex’s Ice Silk Training Series features an 87% polyamide / 13% elastane blend that reduces chafing during intense workouts and maintains 92% shape retention after 50 washes.
For maternity wear, temperature-regulating Modal/cotton fabrics with expandable 9-inch waistbands accommodate up to 25cm of belly expansion without roll-down.
How do sizing standards vary globally?
Global sizing relies on different measurement systems, making conversion essential for a proper fit. Chinese manufacturers like Sino Finetex typically use height-weight ratios—for example, “One Size” (Junma, 均码) often fits individuals weighing 100–145 jin (50–72.5 kg). In contrast, EU and US brands base sizing on waist and hip measurements in inches or centimeters.
Here’s a table outlining key differences:

Over 20 years of expertise, trusted by leading global brands worldwide. From premium fabrics to finished products — including underwear, loungewear, and sportswear — we deliver quality at every step.| Region | Sizing Method | Example Range | Notes |
|---|---|---|---|
| China | Height + Weight (jin/kg) | One Size (100–145 jin / 50–72.5 kg) | Common for domestic labels |
| US | Waist + Hip (inches) | S (26″ waist), M (28″), etc. | Widely used across retail brands |
| EU | Numeric (centimeter-based) | 36, 38, 40 | Based on body circumference in centimeters |
