Assalamualeikum fellow brothers. I have one question that have been nagging me for quite sometime now. you see, i'm a soldier. I was equipped with a some equipments to do my job. one of those were a protection vest. i've been wearing it for as long as my military service. but until recently, i've never bothered to find out more about the vest. recently, i've been googling information about my Protection vest. one thing that i found out is that, my protection vest are of multilayerd design. one of the layer are made of pure silk. now it's not permissible for Muslim male to wear silk. but in my line of job, i need those vest for safety reason. anyone here can help me unravelled this?
