Frogg Toggs Ultra-Lite II suits are constructed from an ultra-lightweight, waterproof, breathable, nonwoven polypropylene material. The patented bilaminate 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 it is perfect for backpacks, stadium seats or golf bags.
