Grade 6A

Silk is classified into 11 grades overall – 6A, 5A, 4A, 3A, 2A, A, B, C, D, E, and F.

At THE ZHAI, we exclusively use Grade 6A silk, the highest quality available. The grading system evaluates size consistency, cleanliness, strength, stretch, and absence of defects. Less than three percent of raw silk reaches this exceptional level, which is why our products feel extraordinarily soft, strong, and luxurious.

OEKO-TEX Certified

At THE ZHAI, we believe you should feel absolutely confident that any silk you put next to your skin is safe, non-toxic, and natural. That's why we've taken the step of certifying all of our products to the rigorous criteria of OEKO-TEX® STANDARD 100. This independent certification means that everything we produce is safe from harmful toxins and chemicals through all phases of manufacturing.
