Your answers are highlighted below.
Question 1
What is wet suit material?
A
Closed-cell neoprene
B
Open cell foam
C
Sponge rubber
Question 1 Explanation: 
Right! In closed-cell neoprene each small bubble (cell) is separate from its neighboring bubble. It, therefore, doesn't absorb water. These separate, individual cells help make neoprene a very comfortable and effective insulating material for wet suits.
Question 2
Which is more important for a wet suit to be more effective?
A
The thickness of the neoprene
B
The fit of the wet suit
C
Color
Question 2 Explanation: 
Yes. Fit is the key. By fitting closely and evenly over the skin, only a small layer of water gets in between the neoprene and your skin. Your body can easily heat this thin layer of water. Remember that your skin would ordinarily be transferring heat directly to the surrounding air and water. Heat and cold do not easily pass through the neoprene because it is an effective insulator. A poor fitting vest or wet suit that allows cool water to wash through would not be as effective. An ordinary t-shirt is, of course, of little benefit because it does not create an insulating barrier necessary to contain body heat.
Question 3
Who needs wet suit protection more?
A
Children
B
Older individuals
C
Slim individuals
D
Tolerance varies by individual
Question 3 Explanation: 
Yes. Although we may think of children, seniors, and lean individuals as the "cold ones", they certainly aren't the only ones who get cold. There are enough examples of over-weight individuals who get cold and children who never seem to get cold to lead to the conclusion that tolerance to cold varies by individual.
Question 4
How is the Wet Wrap different for a traditional wet suit vest?
A
Has a wrap-around design
B
Uses more neoprene
C
Easier to put on and take off.
D
All the above
Question 4 Explanation: 
Right. A shameless plug for our Wet Wrap® vests.
Question 5
The greatest heat loss in water is through the head.
A
True
B
False
Question 5 Explanation: 
Right answer. Our heads are one thing when the rest of our body is fully clothed. Our heads are not as significant when the rest of our body surface is loosing heat in the water. It is estimated that we loose heat 25 times faster in water than in air.
Question 6
How much faster does our body lose heat in water than in air?
A
Same
B
Twice as fast
C
25 times faster
D
100 times faster
Question 6 Explanation: 
Yes. It is estimated that we lose body heat 25 times faster in water than in air.
Question 7
The ideal water temperature for a multi-purpose pool is
A
82 degrees
B
85 degrees
C
90 degrees
D
No single water temperature pleases everyone
Question 7 Explanation: 
Right answer. There are reasons pool temperatures need to be a compromise that can't please everyone. Individuals who get cold have options. They can make personal adjustments using thermal aquatic wear.
Question 8
A vest is effective in slowing overall heat loss in moderate water temperatures despite exposed arms and legs.
A
True
B
False
Question 8 Explanation: 
Yes. A neoprene vest protects the body core and is often all that is needed to avoid becoming unpleasantly chilled.
Question 9
Most people know that wet suits and vests are worn for warmth.
A
True
B
False
Question 9 Explanation: 
Yes. Most people know that wet suits are worn for warmth.
Question 10
Most people understand how wet suits and vests keep you warm.
A
True
B
False
Question 10 Explanation: 
Correct. We think most people know that wet suits are worn for warmth, but most people aren't completely clear on how they work. Wet suits work by fitting close to the skin. A relatively small amount of water seeps in between the wet suit and the wearer's skin. The neoprene wet suit material is such a good insulator it keeps the heat from getting out and repels the surrounding, cooler water. Once the water has seeped in, it's full. More water doesn't enter unless the vest or suit fits poorly.
Question 11
The more vigorous your water activity, the less heat you lose.
A
True
B
False
Question 11 Explanation: 
False is right. You may feel warmer, but you are losing more heat.
Question 12
When were "modern", neoprene wet suits developed?
A
1920's
B
1950's
C
1960's
Question 12 Explanation: 
Correct!
Question 13
A wet suit vest is generally intended for use in water temperatures above 65°.
A
True
B
False
Question 13 Explanation: 
Yes. A vest is partial protection for warmer temperatures.
Question 14
A full ¼" wet suit provides sufficient floatation to keep an individual afloat, but does not provide life jacket protection.
A
True
B
False
Question 14 Explanation: 
True. A full ¼ wet suit is quite buoyant. This is a reason scuba divers wear weights. But, it isn't a floatation device.
Question 15
The Wet Wrap® provides some floatation, but not nearly enough to protect a non-swimmer.
A
True
B
False
Question 15 Explanation: 
True. A non-swimmer is not safe without close supervision in a vest or wet suit.
Question 16
A t-shirt is not very effective in slowing heat loss because it..
A
Lacks the insulating properties of neoprene
B
Soaks up too much water
C
Doesn't fit tight enough .
Question 16 Explanation: 
Yes.Part of the reason. Also, most t-shirts don't fit closely enough to slow heat loss from the body to the water.
Question 17
On the average, people are more tolerant of becoming cold in aquatic activities that non-aquatic activities because:
A
They like the feeling of being chilled
B
The can't afford a wet suit vest
C
They are accustomed to getting out of the water if they get too cold.
Question 17 Explanation: 
Right. On land we put on a sweater or jacket if we get cold. If we get cold in the water, the first thought for most people is to get out. Of course, thermal aquatic wear is "clothing" to wear in the water to prevent becoming chilled before you are ready to get out.
Question 18
The Wet Wrap®, WaterPants™, and WaterShirts™ are designed for water exercise and aquatic therapy and are not suited for other sports such as diving, sailing, or water skiing.
A
True
B
False
Question 18 Explanation: 
False is the answer. Although designed for water exercise and aquatic therapy, these components are well suited for other aquatic activities.
Question 19
A dry suit..
A
Has nothing to do with the water.
B
Is similar to a wet suit except people stay dry.
C
Is worn primarily in sailing where people don't normally need to get wet.
D
Is another name for a survival suit
Question 19 Explanation: 
In a nut shell, yes.
Question 20
If the Wet Wrap® was made of thicker neoprene, it would keep a person warmer.
A
True
B
False
Question 20 Explanation: 
Best answer. Although thicker neoprene insulates more, there comes a point of diminishing returns. Our 1/8" neoprene is the right thickness to be effective in moderate water temperatures.
