Tested for 24 hours near Vancouver, BC.
Water temp 32 air temp 32.

After the 24 hours the participants were doing fine with no cold water issues.

Idea came from an Alaska Airlines pilot.

Not cheap but besides working for at least 4 time longer than older style suits it has a real boot integrated into the suit so you can walk on deck with it.

The gloves are removable and their is a breath operated valve to rewarm your hands once you gloves are put back on.

The idea is that a crew can put the suit on well before it is needed and still carry out their duties.
If they can save the boat just take off the suit.
If they can't they already have the suit on and just have to put on the gloves.

Existing suites can't be put on until you are ready to jump into the water as you cannot walk with them or use your hands.

Once you are in the water they only give you 3 to 6 hours.

Time will tell but it seems like a pretty good idea.

I'll stick with my kayaking drysuits. Immersion time in 42 degree water is more like 1hr than 24, but they are comfortable to wear, provide easy motion, and don't get stuffy even under moderate exertion. I always bring one cruising as my extreme foul weather gear, and also use one when sailing on my 5O5.

That's the thing about this suit.
It is supposedly an honest 24 hours.

They put guys in the water with these suits and after the 24 hours they were willing to continue and had no cold related issues.
