For colder diving would it make sense to layer two 5mm hoods? I have one that I got a really good price on but they only have 5mm's. I was thinking about getting a second one.

It would work but it might be to tight unless the second hood was a larger size. Actually a 5mm hood is plenty warm and good to maybe 50F. if the rest of your suit is doing its job. But then I see where you live. You might be in water colder than 50F

In general layering is not 100% effective. two 5mm layer does not make 10mm. Figure the second layer is only half effective

Be carful a to-tight hood s not good especially if it is tight around the nec

IMHO You'd be better off with a single 7mm. That thickness has kept me comfortable on repetitive ice dives without causing any uncomfortable squeeze.

Yes, hoods are touchy since they will often add a degree of squeeze around the neck. If you don't feel squeeze, you could always try it. It will give more insulation. But my cold water hood is already plenty tight; I wouldn't want to add any onto that... Comfort might be the limiting factor here...

I have a 7mm and have no issues regarding cold down to about 48F. I don't usually go below that temp. The 7mm hood is very doable and warm and usually not the weakest link in you thermal protection.

If the price is really good I might grab the 5mm and try it before getting a 7mm. It should keep you toasty. Having never tried a 5mm myself I really can't make comparisons between the two, but having some experience with cold water I would speculate that the 5mm should perform well.

Everyone has differing tolerances to cold and you will need to do your own experimenting to find your preferences.

Lake MI was 43 at depth last Aug so that is the temp I am looking at. The hood I have is from Tommy D Sports, S & L are $7, XL $10. I am going to order a 7mm suit from them for $80 so I think I will get another hood to try out. For $10 it is worth a try.

You have to do what you think is best for you.....

I see no benefit in doubling up hoods....you will find a better thermal/comfort effect with a quality 7mil hood for cold waters ...... I do have an ice cap I can don under the hood for super long cold water dives.

I'm going to try the two hoods, if it is uncomfortable then I will try the "ice cap" idea and cut the hood down and see how that works. For $10 it's worth experimenting.

Yea at 10 bucks it probably is....let us know what you find out.
