TLS350 Premium Drysuit

Excellent for sport and performance divers, this drysuit has set the industry standard for what divers have come to expect from a drysuit. Durable, fast drying and lightweight for travel. The TLS350 is so versatile that it has become the primary choice for underwater photographers, deep cave explorers and the US Navy SEALs.

By varying the insulation underneath, you can use the TLS in the warm waters of Florida to the ice-covered seas of Antarctica.

H2O Operations Public Safety Premium Drysuit

Meet the DUI H2O Operations drysuit, the first drysuit to address that breathable fabrics should not be used for surface operations as breathable fabric DOES NOT protect operators against contaminants.  The H2O Dual Operations drysuit is revolutionary, designed to provide one suit to meet two different missions: surface operations, which can include swift and flood water rescue, and dive missions.

The fabric is durable yet lightweight and easy to decontaminate.  Available in yellow and black, orange and black and all-black.
