1. The difference between the functions of sports bra vests

(1) The sports bra vest provides certain support and protection to the breast. First of all, it reduces the shaking of the breast during exercise, and what’s more, it reduces the damage to the nipple caused by the friction of clothing.

(2) The sports bra vest is designed with a lot of sports functions in mind, which can provide people with free and comfortable conditions, without restricting movement, so that people can stretch flexibly and freely during exercise.

(3) High-quality sports bra vests have quick-drying function and good air permeability to keep the body surface dry and clean and keep the breast skin healthy.

(4) The structure of sports bra vests is not exactly the same as that of ordinary bras. Ordinary bras do not have that good fixing and supporting effect, and cannot effectively reduce the impact on the breasts during exercise. Secondly, although many ordinary bras also consider the moisture absorption and air permeability of the material, but generally don't put too much effort on quick-drying and perspiration functions. n the end, ordinary bras will have restrictions on movement, which are all determined by the structural design. At the same time, it is worth noting that sports bra vests do not consider too much breast-beautifying effects when they were made, and have little effect on breast shaping, and they are also not suitable for daily clothing.

2. The structure design of sports bra vest

(1) In terms of design, every detail of a sports bra vest is worthy of study. First of all, the shoulder straps are wider than those of ordinary bras, and the seam lines are avoided as much as possible on the shoulder straps. Even if there are seam lines, they are placed at the back of the middle (behind the shoulders). The purpose is to prevent friction between the shoulders and avoid the joints with the greatest range of motion. The design of the back takes into account the anti-skid properties, which is mostly stable structures such as I-shaped, composite or cross. High neck racerback bra is becoming a popular trend nowadays.

The edges of the sports bra vest, such as the neckline and cuffs, will be wrapped, and then zigzag or double stitches will be added to make the edges more smooth and fit the body and prevent the bra from running wild. The lower part is wider in order to reduce the pressure of the bra on the breast and make it comfortable to wear. The part where the button contacts the skin will be covered with a layer of smooth fabric. If there is a dividing line inside the bra, dense Z stitches or binding strips will be used to reduce the friction on the body. The design of the adjusting buckle is mostly metal, and it is wider than the size of ordinary bras. Sports bra vests rarely have the hooks used on the back of ordinary bras, but mostly use wide-sized "9" buckles that can be inserted. These details have fully considered the impact of sports pull on the bra.

(2) In terms of parting lines. The breast parting line, the core part of the sports bra vest is either a structural line that conforms to the trend of muscle movement, or it is a one-piece structure to avoid the parting line from rubbing against the breast.
