Thoughtfully Designed for the Modern You

CottoSilk underwear is engineered for more than just softness. Every pair is created to offer four key things: breathability, stretch, support, and style.

Breathability: Our fabric technology ensures airflow throughout the day, helping reduce moisture and keep you feeling fresh no matter what you're doing.
Stretch: With ultra-flexible blends like Modal-Spandex and Ice Nylon, you can move freely without pinching or sagging.
Support: Strategically placed stitching and a design free from bulky seams or scratchy tags means you get gentle support where you need it.
Style: With cuts and shades that match your mood and outfit, you'll look as good as you feel, even if nobody else sees it.

What Makes Our Underwear Stands Out?

CottoSilk uses an advanced fabric technology that ensures the underwear is comfy in the best way possible. These fabric technology include:

Modal-Spandex

Modal is a form of rayon, a plant-based textile that is blended with spandex to give an ultra-soft and flexible fit that contours your body without even feeling restrictive. It’s ideal for all-day wear and great for sensitive skin.

Ice Nylon

An elastomeric fiber/ material that delivers maximum airflow. It expands up to 500% without breaking, meaning no matter how much you stretch or bend, it bounces right back, making it a great option for active lifestyles.

Cotton-Spandex

There is a reason cotton is the gold standard in comfort. The blend of 95% cotton with 5% spandex, results in a breathable, stretchy material that holds its shape while staying unbelievably soft, wash after wash.

With these advanced fabric innovations, we ensure no matter your body shape or movement, CottoSilk underwear rises to the top of the list.
