Whites Commercial Dry Suit and US Divers Com Hat 1

One of the first suits I bought (1989 - used) the Whites Commercial Dry Suit featured 3/8 " neoprene with heavy rubber reinforcing on the front of the legs, heavy duty boots and extra long wrist seals. Its an excellent suit for cold water diving and very comfortable. The only drawback I found was the excessive ammount of weight required to offset the buoyancy of the thick neoprene.

The helmet in the pictures is the US Divers Com Hat One. The predacessor of the Superlite 17 the Com Hat one was made in the mid 1970's. It featured both demand and free flow breathing systems as well as a liquid filled liner which, while being quite comfortable and offsetting the dead air space well, could also be cold. I've never actually used this helmet, even though the regs are in great shape, the liner leaks like a sieve. The neck seal is a simple neoprene ring which seals against the helmet with a cam system similar to those used on the Superlite.
