Designed and developed according to the requirements of the standard, they have undergone all tests to ensure very good levels of:
abrasion resistance, cut resistance, tear resistance,
seam strength,  
impact attenuation (shell on the joints).
At the same time, chemical tests are conducted on the materials to demonstrate the safety of the treatments used on the leather as well as on the linings.
Finally, ergonomic tests, fitting, and support (wrist tightening) complete this list of requirements.
Quality and durability that meet your expectations!
