PowderStretch is a 4 way stretchy fabric that is mostly used for tights and t-shirts. One side is fleece and the other side is a stretchy lycra® with a smooth durable backing for better layering of clothes. The fabric has wicking/siphoning properties for moving moisture away from the body. It also has odor reducing treatment to inhibit the growth of odor-causing bacteria. Clothing made from PowerStretch is ideal when superior abrasion resistance and maximum freedom of movement is desired such as for climbing/running/cycling/cross-country skiing tights and equestrian pursuits.

There are five weights of PowerStretch: light-weight is 1 mm thick; there's now a 1 1/2 mm thick fabric in navy blue; mid-weight is 2 mm thick; there's a 250 weight which is 2 1/2 mm thick and comes in regular or water-resistant fabric; and heavy-weight PowderStretch is 3 mm thick.

Finally there is a great description of how Power Shield types of fabric works and how to maintain the weather-resisting properties they have. Look at this website of theirs.

Power Shield is a fairly new fabric known as a soft shell. The fabric is extremely abrasion resistant for long lasting durability with a water repellant surface that sheds rain and snow. It blocks 98% of wind to reduce wind chill but is breathable. The clothing provides warmth without the weight and bulk of traditional insulating fabrics. The shell creates less noise than traditional fabrics and is machine washable. Lightweight is 1 mm thick. Midweight is 2 mm thick.

PowderDry keeps the wearer dry and comfortable due to the next-to-the-skin construction. The soft inner layer rapidly wicks perspiration away from the body while the outer layer spreads moisture for maximum evaporation. It is designed to be the first or only layer. PowderDry fabrics are ideal for sports that create significant body moisture due to high exertion and aerobic activity.
