Increase the odds of going home with the advanced hypothermia protection of the Stearns i950 Thermashield 24+ Immersion Suit.
While most suits are designed to protect you in the water for 3-6 hours, this suit is tested at over four times the USCG standard to help ward off critical hypothermia levels for up to 24 hours.
That means rescuers have more time to find you.
The secret is in the patented air-circulating warming system.
By breathing into the systems mouthpiece, the heat normally lost through exhaled air is captured and distributed throughout the suit and the hand warming cuffs.

Other technologies, such as a waterproof zipper, integrated molded boots and gasket-sealed gloves, also help you retain body heat by keeping you dry.
The hard boot soles let you move confidently on deck, while the option of removing your gloves allows you to work more precisely with your hands.
In addition to helping you survive longer in the water, the rescue light pocket and 3M Scotchlite reflective material make it easier to be found day or night.
Once you are found, the built-in rescue harness aids in getting you into the ship or rescue chopper.

Complies with SOLAS Chapter lll, IMO RES.MSC.207.(81) and is U.S. Coast Guard and MED Approved (European Marine Equipment Directive; Ship's Wheel)
