So what do you think would happen
So I know this guy. No not me I swear. Who wears his automatic inflatable life jacket under his foul weather jacket.
So what do you think would happen? It's a pretty good jacket, strong zipper. I'm thinking it will inflate and cause all kinds of bad results. It has to have happened.
Ever seen it it?

Just a guess...but if his jacket remains intact and is zipped up he might find it very difficult to breath due to the pressure on his torso from the inflated PFD. That was something we were very careful not to do when making a parachute jump into water...get out of the harness before inflating the PFD.

Doesn't seem like a wise thing to do.

Not positive, but I believe the directions would say something to the effect, PFD should be worn on the outside! Then again, its been awhile since I looked at the directions of the inflatable PFD's I do have, but they are worn on the out side!

The pfd attachment points on Helly Hansen and other jackets are on the outside.

Check out question 13 on Mustang's Site

:eek: And the question is? Is wearing an inflatable Life Jacket under your foul weather gear would be survivable if he went over....

I imagine he could exhale... Inhale?? that is a different question.:rolleyes:

Well, I see two problems with this...

First, it would delay the inflation of the automatic release and make using the manual release very difficult. This means that he could possibly drown before the foulweather gear let enough water in to trigger the PFD's inflation cycle. Foul weather gear is designed to keep water out, is it not??

Second, it would pose a serious asphixiation risk to the wearer if the PFD does inflate.

As an old Coast Guard ASM..... this sounds... hmmm, how do I put this nicely... Oh.. RETARDED! Why in Neptunes name would you wear something designed to be worn on the outside under your foulies! I'm pretty sure the manufacturer would agree. Just sayin......

Read the directions!
Its specified that you wear them on the outside right on the directions. It makes perfect sense...if you like circulation, breathing, moving, access, etc. Of course they look less conspicuous and stylish if worn under windbreakers or sweats...
