ABSTRACT:
A cold weather garment system includes an upper body garment and a lower body garment. Each garment has three layers, an outer wind resistant shell fabric, an inner loosely knit or woven lining fabric, and a non-flat foam layer between the fabric layers. The face of the foam layer abutting the inner lining fabric is convoluted, having peaks and valleys. The peaks are disposed in a grid-like arrangement, with ridges between the peaks, and four peaks surrounding a valley, and four valleys surrounding a peak. The foam is open cell polyurethane or polyether foam, and has a thickness of at least 1/2 inch, and preferably about one inch. The thickness of the valley portions of the foam is about 1/2 that of the peak portions. The convoluted form of the foam increases flexibility and reduces material and weight, and provides added surface area for moisture transfer.
