Frequently Asked Questions (FAQs)

1. What are competitive swim suits called?

The style of men's competition swimsuits is called a jammer. With the extreme focus placed on compression technology, you can easily see why. As suit rules have ebbed and flowed over the years, current international specifications dictate a suit for men that can run only from the belly button to the top of the knees.

2. What is a two piece bathing suit called?

A bikini is a women's two-piece swimsuit featuring two triangles of fabric on top that cover the woman's breasts, and two triangles of fabric on the bottom: the front covering the pelvis but exposing the navel, and the back covering the buttocks.

3. What are girls swim suits called?

A one-piece swimsuit most commonly refers to swimwear worn primarily by women and girls when swimming in the sea or in a swimming pool, playing water polo, or for any activity in the sun, such as sun bathing.

4. How should a competitive swimsuit fit?

Competition Swimsuit Fit Guide A properly fitting swimsuit should fit closely against your body. Bunching at the seams or tightness and pulling at the straps and openings usually indicates an incorrect size. You should be able to move freely without causing the neck or leg openings of the suit to stretch.
