What role do the shoulder straps play when their widths differ at 12mm and 30mm?
This is when you see the shoulder strap widths listed differently as 12mm and 30mm in the sports bra specifications and wonder what use the 2 straps each have.
The brand only reveals the specification that 12mm and 30mm straps are included, but generally, a combination of shoulder straps with different widths helps share the roles of securing support and providing comfortable movement.
They are 30mm and 12mm. These are the specifications actually used for the shoulder straps of WELTER EXPERIMENT's Double-Layered Sports Bra[1]. The brand applied two different widths together to the shoulder straps[2].
The roles are divided. Generally, a wide strap like 30mm widely distributes the pressure transmitted to the shoulders, supporting the upper body with a sense of stability. On the other hand, a narrow 12mm strap reduces the contact area when moving around the joints and collarbone, making movement feel much lighter. It is a configuration aimed at obtaining both the solid support of a wide strap and the flexible movement of a thin strap at the same time.
hmmm, behind the layered look, a functional combination aimed at relieving the burden on the shoulders during exercise is naturally connected.
It has not yet been confirmed which parts of the chest and shoulders the two straps are positioned to support respectively.
