Our Fabrics

The best protection without the weight

Our Approach

We don't chase gimmicks or fads. We simply want to build the best product that will last you, hopefully, decades. To that end, we search out some of the finest fabrics in the world, looking for the best combination of weight savings, weather protection, and longevity.

Exquisite Cotton

Delightfully smooth | Durable | Downproof
Introducing Organic Cotton

For 2024, we're proud to introduce our full line of new bedding sheets - duvet covers, sheet sets, pillowcases, pillow shams - made from 100% organic cotton certified to the Global Organic Textile Standard (GOTS).

Extraordinary Organic Cotton

Our founders searched for years to find an organic cotton fabric that meets Feathered Friends' high standards for comfort, quality, and durability. Woven from premium extra-long staple fibers and finished with a soft sateen weave, these 100% organic sheets and duvet covers are luxuriously soft and breathable.

For those looking to go as natural as possible, we offer an unbleached, undyed, minimally processed "Natural" color. With the same soft hand feel as our other organic cotton fabrics, the Natural color will contain small cotton seed particles that show up as very small black or brown spots in the fabric.

Our 100% organic cotton duvet covers and sheets are made with care in a Fair Trade Certified factory in India. Like Feathered Friends, the Indian mill we work with is a second-generation family run business started by a female entrepreneur. The extra long staple cotton fibers are woven into a 400 thread count sateen finish, resulting in a soft and luxurious feel.

Organic Cotton Colors
Long Staple Cotton

Be wary of inflated numbers. We use 400 thread-count, single ply, evenly woven cambric cotton ticking on all of our down comforters and pillows. This assures the tightest weave for a soft hand and superior performance year after year.
