Using the same Polypropylene staple that is blended with our cotton products found in the active-wear line, Forces of Nature discovered the unique performance properties found in knitwear could be engineered into a full line of outerwear using the New Fiber called Ultra-Fill. Ultra-fill polypropylene replaces down feathers and/or hallow fill /other polyester fiber fills in the inner jacket panels. The results have been impressive to say the least.

Almost double the CLO thermal retention of heat  plus a much lighter weight jacket and less bulkier jacket, LESS LAYERING...MORE THERMAL.. MORE FUNCTIONAL
