MD4031

One vest to take you into your many inshore marine adventures. And, one of the most exciting innovations to come out of the Mustang Survival Waterlife Studio. Why? They took the most loved inflatable and made it even more flexible, comfortable and lightweight - without compromising on durability, quality, or safety. The M.I.T.™ 70 is the smallest inflatable PFD approved in North America, making it your new favorite vest to pack for every inshore adventure.

Exclusive Membrane Inflatable Technology™ (M.I.T.) creates a lightweight, flexible fit.Manual inflation inflates by pulling the inflation handle. Easy-access inflator eases re-arming. High visibility, contrasting fabric when inflated for increased visibility in rescue scenarios.

This easy to wear and easy to use automatic inflatable PFD features Mustang Survival Membrane Inflatable Technology™ inside to reduce product weight and create a lighter and more flexible fit. Membrane Inflatable Technology M.I.T.™ is a brand new inflatable technology used exclusively in Mustang Survival's next generation of inflatable PFD's. Designed by Mustang Survival's industry leading team of Research and Development experts, M.I.T.™ inflatable PFD's use stretch materials derived from the medical industry. By using less fabric and lighter weight components in this design the MD4031 provides an overall lighter, more flexible and comfortable fit. MD4031 M.I.T.™ Manual Inflatable PFD is approved for use by both the US Coast Guard and Transport Canada and provides substantially more buoyancy than an average person needs to float.

HARMONIZED APPROVAL

The United States and Canada are working together to harmonize flotation standards. The purpose is to make it easier for waterlife enthusiasts to enjoy their time on the water through improved product offerings and streamlined regulations. Simplified regulations offer less complexity and increased function making it easier for boaters to comply with local regulations.

Formula to Determine Buoyancy

If a man weighs 200 pounds on land, he only weighs 10 pounds in the water.

80% of the human body is water. Water in the body has no weight in the water.

200 pounds x 80% = 160 pounds
200 pounds – 160 pounds = 40 pounds

The human body is 15% fat, fat is lighter than water.

200 pounds x 15% = 30 pounds
40 pounds – 30 pounds = 10 pounds

A 200 pound person only weighs 10 pounds in the water.

A U.S.C.G. approved Type V vest is mandated to have 17.5 pounds of buoyancy.

If a man weighs 350 pounds on land, he only weighs:

80% of the human body is water. Water in the body has no weight in the water.

350 x 80% = 280 pounds
350 pounds – 280 pounds = 70 pounds

The human body is 15% fat, fat is lighter than water.

350 pounds x 15% = 52.5 pounds
70 pounds – 52.5 pounds = 17.5 pounds

A 350 pound person weighs 17.5 pounds in the water.
