Polartec Alpha Direct is an evolution of the original Alpha insulation that eliminates the need for a backing fabric. Alpha Direct can be worn directly against the skin or other fabric layers. This increases the breathability, reduces the overall garment weight and allows for greater creativity in terms of styling. Alpha was originally developed for the U.S. Special Forces when they required a more advanced insulating material in their uniforms that could regulate body temperature during the starting and stopping of active combat. This latest advancement in adaptable breathability helps eliminate the need of shedding or adding layers while on the move. Alpha is also hydrophobic, so it won't absorb moisture even if you start to sweat.
By placing patented low-density fibers between air permeable woven layers Polartec® created a more efficient fabric for regulating warmth and transferring moisture. This advancement increases thermal adaptability in changing conditions and different phases of physical activity.
Alpha Direct can be used as an insulation/lining or can be made into a stand-alone garment. It makes a great mid layer for wearing under a waterproof shell such as Neoshell. While Alpha Direct is slightly more durable than Alpha, both can be used as liners or stand alone garments. All Polartec® fabrics are certified Standard 100 by OEKO-TEX®.
