It's Cold in the water so you need something to keep you warm. That is what wetsuits, swim skins and dry suits are all about. Keeping you warm in the water. We know wetsuits...it's cold here in the water in Iowa.
HOW DOES A WETSUIT WORK?
Wetsuits are primarily made of closed cell neoprene rubber in a bunch of different versions, qualities, thicknesses and materials. Not all wetsuits are the same. Not all neoprene is the same. Higher qualities of neoprene keep you warmer, wear better, fit better, feel better and look better.
Most wetsuits and drysuits use neoprene, a synthetic rubber that is waterproof, insulated and flexible
Lycra, a type of nylon, is used in thinner suits. These are more flexible buy are most appropriate for diving in warm and shallow waters.
The inside and outside of wetsuits and drysuits typically have a nylon fabric laminated to the neoprene. This helps resist tearing and abrasion.
Manufacturers use different stitching techniques to increase the seal at the seams. These are usually glued and blindstitched or glued and taped.
Styles (wetsuit lingo here!)
Shorty - Short arms and legs
Full or Jump - Full arms and legs
Corewarmer or short john - Short legs, sleeveless arms
John or Jane - Sleeveless w/full legs
Jacket - Essentially a shorty with long arms and zipper front. Can be worn alone or over a john or jane
Vests - Sleeveless Top may have a attached hood or zipper.
Shorts - ahhh .. Shorts!
Dry suit - If your watersports conditions are in really cold water or deep depths, you may want to consider a drysuit Designed to keep as much water out as possible by using rubber seals around the neck, wrists and ankles. You actually wear undergarments under these. AND is all is well...you stay dry..even under water!
Materials
Lycra - just lycra. No thermal protection, primarily for UV protection primarily rash guards and skins. A nice undergarment too!
TLN - An Aquasphere proprietary material. Blend of teflon, lycra and neoprene for warmth and mobility in swimming
Neoprene - Different types available based on qualities and costs. Normally nylon exterior and interior
Stretch Neoprenes (ie Hyperstretch, Hyrdoflex..etc) Neoprenes that can stretch up to 2.5 times their original size.
Skin out or rubber out neoprene - rubber neoprene is not covered. Typical on Triathlon suits and steamers
Wetsuits keep your body warm a couple of ways.
First, they trap a thin layer of water between your suit and skin to reduce heat loss. That's done by the neoprene which traps air bubbles to provide the insulation.
Second, by keeping cold water away from your skin, you receive further insulation
SO..."The warmer the water, the less protection you need; the colder the water, the more protection you want"
Thickness is expressed in millimeters ( ie: .5mm - really thin and 7mm - thickest)
Thicker wetsuits provide greater insulation, but the quality of the material plays a part as well
SO WHICH SUIT FOR ME...
There are a bunch of factors that determine what suit style and thickness you want to choose. The primary factors are:
What sport you are going to use them for?
What the water temperature is?
What the water conditions are?
How much activity you are going to have?
How cold you get --- (women get colder then men!)
How much your weight fluctuates
How comfortable you want the suit to be?
1) What Sport are you using it for?
Different sports make a difference on the suit you buy here are some thoughts. Lots of different suits will work for different things, these are just some tips.
Waterskiing, wakeboarding a watersports shorty or full suit is fine. Actually anything seems to work fine here. But remember mobility and comfort!
Swimming or Triathlon you need a suit that is more flexible and allows full range of motion (Scuba suits..don't work very well) Skin out suits are the norm for speed!
Scuba diving, due to wetsuit compression at depth, and lowere activity, you may want to stick with the higher quality neoprenes and most coverage you can get. See water temp and depth below. Avoid skin out suits for diving.
Paddling...a paddle john with a jacket is the most comfortable. If you are going to get wet alot, then the addition of a Jacket may be in order
Windsufing as skin out suit or steamer is the most popular to allow for wind blockage
Sailing, skin out suits work well, johns with a jacket also.
Snorkeling...shorties, full suits skins and microprene 1mm suits rule!
Water temperatures and depths - DIVERS...do you remember your atmospheres of water pressure from scuba school....???
Remember...at 66 feet you are at 3 ATM. So that is three times as much pressure at the surface. Your wetsuit can loose as much as half it's insulation at that depth! (ouch...so plan for it!)
OTHER STUFF - Accessories and such
Hoods and Beanies
You lose nearly 40 percent of your body heat through your head
A hood is a must for extremely cold diving
A beanie is awesome for even warm water. (great to keep the hair in too!)
A good fitting wetsuit will be comfortable, and not too loose or tight
They should fit snuggly and comforatble.. but shouldn't restrict your movement or breathing. We advise folks to try them on and if you can stand around and chat with someone for 10 min and feel comfortable..you probably have a good fit.
If a suit is too loose, you allow water to enter, defeating its purpose
