Since life jackets are too big as an alternative that offers buoyancy, some manufacturers chose floating collars as another option. It perfectly works in keeping the head of the wearer afloat. To use it, you must manually inflate it once you’re in the water.

3.2 Thermal Insulation and Waterproofing

The main purpose of immersion suits to the maritime industry is floating survival equipment worn by crew members or passengers during emergency situations. Because of this, it is designed to protect the wearers from hypothermia or the sudden fall in the body temperature. The appropriate detail of the suit is that it can drop a person’s body temperature by more than 2 degrees, especially when it’s floating in the water for hours already.

Aside from the thermal insulation detail, an immersion suit must be made primarily with waterproof materials to keep afloat and prevent the wearer from drowning. The two factors mentioned are essential since they show how an immersion suit can be practical, functional, and ideal.

3.3 Sizing and Fit

Every person’s size varies, and it is one of the most important factors to consider when choosing an immersion suit. The sizing and fitting must be appropriate to achieve its utmost protection and take advantage of its functions and features. Following the standard and average measurements would be best to avoid further complications and troubles.
