Looking for some ideas on my problem with cold water hoods. I have logged about 20 dives and to date, have not found the proper hood or a solution to the problem I'm having with my hood. My hood fills so much with air, that I can't keep my mask sealed because the strap is moving around so much. My buddies say I have a huge air bubble in about 30 seconds after I'm under water. I don't know where all the air is coming from and it has happened in rentals, BARE, Henderson, all the hoods I've tried. Any idea what I'm doing wrong, or what is going wrong? Thanks for any suggestions you have.

Take a small diameter piece of metal, get it very hot, and make a small hole in the top of your hood. The hole will vent the air but will not allow any appreciable amount of water to enter.
carolhd:
Quite possibly exhaling through your nose either unintentionally or when you clear your mask. Some hoods come with built in vents for the air to escape through. My hoods didn't have that so I put some very small holes in them to let the air out.

This is why I love this board. You can always count on picking up little bits of useful info. I've had the same problem with air in my hood, not as bad as Carolhd, but no one has previously given me this tip. Thanks!

I see Kracken and I posted at about the same time. I used the same method he mentioned and will add that the wire must be very thin. The nylon and neoprene will shrink away from the hot wire as it melts and you can end up witha fairly large hole instead a small one

Well crap, now I'm afraid to try it because with my luck I'll come out with a big hole. I'll give it a try anyway. Thanks.

Don't overlook this advice either - have someone watch you as you breath - I'll bet there is air coming from the edges of your mask as you exhale through your nose as well as out the reg exhaust.

Had the same problem because of often exhaling through my nose slightly (less bubbles and I kind of like the tranquility of it). It became difficult to remain neutral at the end of long, shallow dives! On the other hand its almost as if you dive dry 
The needle did it, and my buddies now have something to laugh when looking at me - a constant flow of smallish bubbles coming "out of my head"....

With a hot soldering iron or similar punch 3 holes in the top of the hood. This will allow air to vent whilst not fray the material.
Also breathing out through your nose can channel air into the hood via the mask (then again i find exhaust bubbles from my reg also end up in mine).
The other solution i sometimes use although i wouldnt recommend it is to periodically hit myself on the top of the head to remove air

Some hoods are made with holes in the top.
When you do get some air in the hood just reach upa nd pat yourself on the head. That will force the air out.
Of course it will also help if the hood fits you correctly.
