Mustang products are designed as survival clothing. Float, insulation and more important impermeable. You will sweat your butt off during activity. This is when mine is either full open or not worn at that time. I have the full atlantic class exposure suit. These excell when in the harsh conditions of wind and water in dirty cold sub sub zero temps. I use it for travel on ATV or sled over water. Great. You can stand out unprotected allll day in the worst cold and wind. Dont sweat inside these. Remove the upper layer or take it off when working. The suit gets stiff enough when its -20 celcius. dont make it wet from sweat and let it freeze LOL.
When you go thru the ice , get dunked and crawl back out on to the ice.... the suit significantly reduces the wind from stealing your vital body heat. This is the exposure the suit was designed to reduce - loss of heat in and out of the water. After a few minutes of standing and the residual water runs out the wrists and ankles. You will be walking again and generating needed heat. Without a survival suit on ..... you may not be able to walk before exposure is a greater problem. Serious !
