Air in Scubapro Hood

[Compressor]

I seem to be developing a big head underwater due to air seeping into my Scubapro Everflex hood. The hood has a vent; not sure what the problem is as on some dives there is no issue but on other dives my hood annoyingly bulges with air. The mask seal is on my face not on the hood. I thought I ask this here before making the holes in my hood bigger which can potentially create a bigger rip.

Most manufacturers of hoods put vents at the top of the hood (top of the head) that end up in horizontal position when diving so air is trapped at the highest point which is the "back" of the head/hood. I usually use a nail to put holes at what will be the highest point in the head/hood while diving which is the back of the head/hood.

Thanks BurhanMuntasser; a simple solution indeed.

I have observed that it is from the mask how the air gets under the hood. May be trimming a larger face opening can help, so that the mask skirt doesn't reach under the hood?

There may be something to the last post as when I pushed the hood back away from my face, the problem lessened significantly.

Keep the air in your hood. It isolates and keeps you warm

Not really. The air creates a space between the hood and the head, and invites icy water to enter.

Do you heat the nail first? I'm thinking of experimenting on my old hood before trying with my nice, expensive warm one (from Waterproof)

Just roll over onto your back slightly and the air will escape...

I didn't but I used small nail. Try it and let us know.
