كيفية تليين سترة دراجة نارية جلدية جديدة؟

To break in and soften up a new stiff leather jacket: Wear and move around in it as much as possible initially to loosen up and warm the leather’s fibers. Use a leather conditioner product to help soften. Put the jacket on and tightly hug yourself, twisting at the waist to make the leather flex. Carefully use a leather mallet to pound and relax the chassis.
