OS SYSTEMS is now applying the technology learned and materials discovered from our many years of military work and development to produce the microporous, breathable and totally waterproof Stealth Chest Waders.
Only OS SYSTEMS Stealth Chest Waders and waders made from Gore-tex®, can be labeled "microporous". Microporous is defined as a waterproof, breathable membrane made from ePTFE (expanded Polytetraflouroethylene = microporous teflon membrane).
Microporous membranes, when reinforced by a hydrophilic (water loving) layer of polyurethane, provide the best and most durable waterproofing available. Only OS SYSTEMS Stealth Chest Waders and waders made from Gore-Tex Immersion Technology fabric meet this requirement.
All other waterproof/breathable membranes are made only from hydrophilic urethane … less expensive, less effective and less durable.
