Microfiber is the key to the incredible warmth and softness of the ATI Emergency Blanket. The microfiber material used in the ATI Emergency Blanket is lint free, and incorporates millions of microscopic pores within the fibers. This is what gives our blanket its incredible warmth and softness. The ability to trap air in the microscopic pores creates an insulating barrier between you and the elements. The extra tight weave allows the blanket to fold into a compact bundle and also prevents penetration by harsh wind or breezes. The ATI Microfiber Emergency Blanket can be used in conjunction with reflective blankets, tarps or ponchos for added protection from the elements. Place the ATI blanket between you and the reflective blanket, tarp or poncho to keep you dry and to create a soft insulating layer between you and the outside word.
