A wetsuit allows a thin layer of water between the suit and your body. Your body temp then warms the water and helps you stay warm in cooler than body temp waters. Wetsuits can be worn by anyone at anytime. A dry suit is a "rubber" (for lack of the proper word) suit that allows NO water inside. You stay warm by wearing thicker undergarments and keeping water out. A dry suit takes special training to wear. It has an inflater hose attached to it to help in attaining neutral buoyancy and learning to use it takes practice. Dry suits also cost between $800-$2000.
Repairs? I would think a wetsuit could just be sewn back together. A dry suit could be repaired with a patch kit (kind of like an tire inner tube would use, but made for underwater applications) |
I dive dry almost all the time, so I'll add my 2 cents.
No suit is totally dry, some water always gets in, the less the better.
Drysuits can be made from a number of different materials: usually a tough nylon-type fabric or neoprene (which provides some or all of the warmth). The wrist and neck seals are latex.
Wetsuits are repaired with neoprene adhesive.
Quick repairs on drysuits are made with man's best friend, duct tape. Permanent fixes are with patch kits.
There is a hybrid type of suit, the semi-dry. It is a wetsuit with rubber gaskets on the inside by the wrists, ankles, and neck. These restrict water flow, keeping warmer water inside. They can be pretty darn toasty.
