This ad really stands out from all the rest because main thing that you see is a pad cut out from an athletic shirt.  Normally with pad ads its just showing possibly a happier woman standing there or how flexible the pads are.  But this one, to me, kind of says hey I'm athletic and flexible.  This is also unrealistic because pads aren't just cut out from shirts and said that they are comfortable.  Most aren't.  
The main target audience is obviously women, basically of any age or social class because the product isn't expensive.
In this ad, the people who wrote it use only one of the needs which is need to satisfy curiosity.  I see this because the women looking at this ad do not know if the pad will be comfortable like athletic wear is.  So it some-what attracts their attention and curiosity to make them go out and buy the product to see if it does feel a certain way.  
The many advertising techniques that are used are weasel words, transfer/association, plain folks, and a bit of repetition.  
The weasel words that are mentioned in this ad are dry-cool, comfort, quickly, stay dry, cool, and comfortable.  You do not know for sure if any of these things will actually work.  To stay dry, cool and comfortable is all based on weather the customer likes the product and has this reaction.  But everyone is different.  
Transfer and association is really similar to the weasel words.  The words and phrases that transfer and association are aiming towards are wicks moisture away, comfortable, and stay dry.  All of these kind of depend on the customer and their opinion on weather it wicks away the moisture, etc.  
Repetition is used very little but the only thing that they really repeat is comfort and comfortable.  This word is mentioned at the beginning and the end to introduce it and to also make sure it is the last word that the woman sees to emphasize that the pad is comfortable.
And lastly plain folks is related with this ad because the product isn't expensive enough to make it seem like richer people buy this product.  People of all classes can buy it.
