3mm of neoprene to keep your feet warm? That will compress at depth giving the diver little to no thermal protection?
I don't think so.
Neoprene material can be utilized as a "thermaly correct" material to reduce heat loss in a number of manners. It is true that at depth neoprene compresses and loses some insulation properties.
This is common knowledge.
However in a Drysuit you are adding air to offset a squeeze which allows your undergarments to retain some loft and greater insulation properties.
Also the 3mm neoprene sock is not designed to provide warmth in the same manner as a wetsuit (trapping water next to your body thus allowing it to be heated) Instead the neoprene in the 3mm sock is used to trap your body heat and prevent it from escaping. Also it provides that extra barrier between a divers body and the actual shell of the suit which creates the "layering" effect.
I will agree that these socks have thier limitations and every diver reatins heat at various levels. I personally dive the 3mm sock in the Pacific North West on a weekly basis and it works great for me, but i do know divers who require more warmth.
The Whites MK3 sock is a great option for the ultimate in warmth. It contains Primaloft, the same insulating material as our MK3.
