Frostline Kits in Grand Junction manufactures high-quality, unassembled, winter gear kits. These kits include an instruction manual, cut-to-size fabric, down or other fill materials, and all the thread and finishing items needed to create a top-notch jacket. The only thing you have to do is provide the sewing machine and some time and labor. Because they do not sew your outdoor gear themselves, the savings trickle down to you. You can purchase a ladies' polar fleece jacket kit for $38 or a tundra jacket kit (a down-filled coat that is unbelievably warm) for $115. So sew.
