Frogg Toggs suits are constructed from an ultra-lite waterproof, breathable, nonwoven polypropylene fabric. The patented bi-laminate technology with "welded" waterproof seams and unmatched sweat-free breathability is a great value in affordable rain wear. The compression packability of this suit allows it to pack down to "storage pocket" size, and is perfect for backpacks, stadium seats or golf bags. Wt: 10. 4 oz.
