What do you mean by hanging your pants for a few days? Suspension pants usually refer to pants with suspension and buoyancy functions. And "D" indicates the suspension ability of these pants, usually 1D, 2D, 3D and so on. Common suspended pants are mainly composed of airbags and air pumps, which can provide excellent buoyancy in water and help people swim and snorkel more easily.

When buying suspenders, you must pay attention to the D value of the suspenders you choose. Different values of d represent different suspension forces. Generally speaking, 1D suspension pants can only provide slight buoyancy, which is suitable for people who are good at swimming and water sports. Suspenders of 2D or above are more suitable for beginners or swimmers who need extra buoyancy.

As a kind of water sports equipment, suspended pants have floating function, which can not only help people swim easily in the water, but also ensure people's safety. Therefore, if you are a person who loves water sports and want to relax more when swimming and snorkeling, you may wish to consider buying a pair of suspenders with a suitable D value.
