This is the THE NORTH FACE Obsession Climbing Pants, model number NB32002. The color is Fir Green (FE), size M. The material is 91% nylon and 9% polyurethane. [Product Overview] These climbing pants were developed through scientific analysis of climbing movements. They are designed with a focus on high steps, where the legs are raised significantly, a common movement in climbing where the body's sides are often engaged. By eliminating seams in the inner thigh area, where stretch is most needed, the pants maximize the inherent elasticity of the material, allowing for dynamic movement. The knee panel uses a bonded construction to reduce seam irritation and facilitate leg raises. The pants use a durable 4-way nylon stretch material, suitable for both indoor and outdoor use. They also feature an electrostatic care design to suppress static electricity. These high-performance bottoms incorporate knowledge gained from the development of the Japanese national team uniforms.
