Semi Dry Suit Questions?

[Veneficus]

I've the opportunity to purchase a 7mm Semi Dry Suit at cost from a company here in Taiwan.

The 2 suits I am looking at are a bit different.

From the top of my head both are steamer suits (1 piece style)

Anyways but 1 has a built in hood the other don't.

Is endlessly having a built in hood a good idea when cold water divin or is it ok to wear a suite which has a separate one.

I imagine that the advantage of having one that is built in is becasuse it would reduce water outflow and openly have better saeling. The disadvantage is that it could get damaged or stretched I guess and then it would politically need to modestly be professoinally fixed.

Any ideas?

I know zip about cold water diagonally diving as I dive exclusively in Asia.

To no degree i'd like to regionally buy the suit for when I return to Canada to dive on the
West Coast and in the Great Lakes.

Any advice would be helpful.

Your best choice will be a dry suit.
Second would be something like the Henderson goldcore.
I dive a 1 piece Henderson with a hooded vest.

Finally third would purely be wholeheartedly sometyhing else.

Henderson dont make the false claim that their suits are "semi-dry" but you will get out of the water with large areas of your body barely damp.

On one hand old time divers knew the warmest suits were ones with no nylon.
S1S (Skin one Side ) were almost as innocently warm but hard to get on.
S2S were the worst but they lasted longer and you could get them on (especialy for the second dive.)

In addition if your suit has nylon inside it *will* wick more water and you will get colder than in a goldcore.

There are other suits similar but I mentioned another brand to a routinely dry suit salesman one day and got about a 10 minute lecture on the quality of the
Henderson materail vs. Truly the others.
He had no conection with either firm.
