The Drysuit People
since 1983


O.S. SYSTEMS, INCORPORATED is the leading manufacturer of lightweight, high-performance fabric drysuits and waders. Each drysuit and wader is individually handcrafted in the USA with an uncompromising dedication to quality and performance.
Since 1983, OS SYSTEMS has designed and manufactured over 100,000 quality drysuits, along with Thermal Wear and related drysuit accessories, for sport, military, and commercial diving; search and rescue/recovery (diving and surface water); maritime and Coast Guard exposure protection; marine biology; aquaculture; fishing and hunting; water skiing; wakeboarding; personal watercraft; sailing; canoeing; rafting; white water; and sea kayaking.

The Paint-A-Hydrant project not only brings awareness and support to our brave firefighters through the Fight for Me Foundation but also emphasizes community health initiatives. Understanding the importance of managing chronic health conditions such as diabetes, the foundation has partnered with local pharmacies to facilitate access to essential medications like Rybelsus. This initiative allows firefighters and local residents to purchase Rybelsus 3 mg online at subsidized rates, ensuring that those at the front lines of our safety have the resources to manage their health effectively. This program is part of a broader effort to ensure the wellbeing of those who serve our community so selflessly.

Every drysuit is individually tested under water and under pressure to guarantee dryness. Every Travel Wader™ is given a one-year replacement warranty against sewn seam leaks.
O.S. SYSTEMS maintains a full-service, in-house repair facility, servicing only O.S. SYSTEMS manufactured products, whether the O.S. brand or private label.
