  • Unique Buckle

    The KUMAY lever buckle is constructed of zinc alloy, setting it apart from the majority on the market that use casting pewter tin-lead alloy.

    The tensile strength of zinc alloy is about 35 kgf/mm² (350 MPa), Stainless steel lever buckle is constructed using CNC wire cut technology, setting it apart from the majority on the market that use casting pewter tin-lead alloy.
    The tensile strength of stainless steel is about 45 kgf/mm² (450 MPa)which is much stronger than the pewter tin-lead alloy buckle commonly found in the market, which has a tensile strength of only 7 kgf/mm² (70 MPa).Zinc alloy can significantly extend the lifespan of the buckle, whereas the pewter tin-lead alloy buckle is fragile and prone to breakage. When squatting, there is a high risk of the pewter tin-lead alloy buckle snapping, potentially leading to casualties.

  • Sufficient leather belt

    The KUMAY belt is 4 inches (10 cm) wide and has a thickness of 12 mm. It offers substantial support. Many inexpensive belts on the market are advertised as 10 mm, but they typically measure only 7-8 mm, reducing the belt's strength.    The belt is made of split leather, neither too hard nor too soft. However, cheap belts on the market are made of split or bonded leather.

  • Vegetable Oil Tanned Top Grain Leather

    The belt is made of premium vegetable oil-tanned top-grain leather. Cheap belts are usually made of split leather or bonded leather.

    Neither too firm nor too soft, this belt is made of soft yet durable leather that conforms to the user's waist, creating an hourglass shape.

    We are convinced that willows are weak yet they bind other wood. The soft but tenacious leather belt can boost the performance of the user. It can absorb the intra-abdominal hypertension of the user due to its ductility.

    Too stiff a leather belt is like a high rigidity body structure vehicle on crash test. Passengers inside the car will roll over because of the inertia at the bumping moment. And cause casualties.

    Moderate hardness belt provides an ideal crumple zone to absorb the impact immediately.

  • One Cut Leather

    Our belt is made of complete pieces of leather without any splicing. Users can inspect the edges of the belt to verify this. It provides effective support. In contrast, inexpensive belts are often made of spliced leather to lower costs, resulting in some hollow areas inside.

    It is not only an aesthetic issue but also an effect issue. Cheap and soft belts can not provide substantial support due to their softness.

  • Internal Edge Round

    The edges and corners of the belt are ground to have 3-4mm rounded corners and fillets inside to spread the stress, making it comfortable for users. The leather is neither too hard nor too soft, with smooth edges that allow for more flowing movements during squats or deadlifts.

    Some belts on the market have sharp edges and corners that can rub against the pelvis and rib, causing pain and disrupting movement during squats or deadlifts. For example, feeling pain during deadlifts can lead to distracted movements, such as the hips rising and knees straightening before the upper body is erect, increasing the risk of low back injury.

    To dispel a myth. Edge rounding will not reduce the capability because decreases the touching area. On the contrary, it can increase the touching area spread the stress, and then boost the performance of the belt.
