I went into a Body Armour retail outlet at Birch Run on the weekened and was told that they didn't have anything for under scuba gear. I have been told not to put cotten against my skin under the wet suit because it actually directs heat away from the body. Am I best to look at a 5mm? (5/3 full?) I also plan to dive in the Red Sea in November of 2011. If I invest in a 5mm now will I be able to use it there, or will I be back in my 3/2? Any ideas or input would be helpful here.
There are a couple of options that work well, depending on several personal preferences..
1. If you don't mind hoods (I hate them, but like being warm), then a hooded vest works wonders, first by reducing water in and out of the suit, and second, by adding some insulation in a key area.
2. Just a vest also works... but is nowhere near as warm.
3. A heavier pile jumpsuit under the suit. Pinacle has a very nice one at a reasonable price... I have that one and a heavier Oneal one from stretch stuff. Both are comfortable, both reduce water movement and both are warmer....but they trap a lot of water, so you will weigh a lot move getting out than you did going in... still they work.
4. Wear a cap, good gloves and good boots.. they help. Not as much as a hooded vest, but it helps.
Ok, I own a lot of wetsuits..11 if I remember correctly, and I take pictures (meaning I don't move a lot at times), so I get cold...I use a 5mm in in bahama's or a 4/3 with hooded vest, or a two piece 3mm... or a 3mm with a jump suit under it...
Hope that helps
