Today's performance stretch fabrics need to adapt to the contours of the human body for optimal comfort during movement.
Polartec® Power Stretch® Pro™ has reinforced elastic fibers creating 4-way stretch that meets the demanding push and pull of activity. This agile, dual-surface fabric absorbs moisture from the skin while continuously wicking it to the outer layer for fast evaporation. Power Stretch® Pro™’s outer surface has a low-friction finish, so this versatile fabric can layer perfectly with others and resist abrasion on its own.
What does it mean when a fabric "bags out"?
Never lose your form !

A fabric has bagged-out when it is overstretched to the point that it will not recover. This condition is most often seen around the elbows or knees. Polartec® Power Stretch® Pro™ uses a combination of high stretch yarns, like spandex, and specialized constructions to assure that garments do not suffer from bag-out.
