What jacket do you wear on your boat?

Mustang HIT. It's comfortable and I hope it works if the need arises. My Dad has a few non-HIT inflatables and all have discharged at one time or another from getting too wet or damp in a locker.
Unfortunately it's time to replace the one I have, as it's becoming quite worn.

Same for me, HIT. If getting an auto, HIT is the way to go. Pill models too may stories of deploying in rain, rod locker, splashing, etc. There are tons of pill models out there being used as they are lower cost compared to HIT - , MLF uses Onyx for instance - but for me HIT was easy choice.

How long do they last?

Do they expire?

the HIT "kit" is good for 5 years, replacement kits usually $60-70 online.
