Mountaineering is not an impulsive activity. It requires proper planning and preparation which would not be complete without certain polymers.
You need breathable clothes in which you can easily move around. Most of these clothes are made of nylon. You need strong ropes made of synthetic fibres and shoes with a firm grip. Hiking and mountaineering shoes are often made of materials like rubber with laces made of fibres like kevlar.
You need a good backpack and that is made of a set of polymers. The bottles that you carry water in are yet another thing made of polymers.
