Riding pants are integral part of riding gear for rider safety. These pants have built in knee protector and would have foam padding at hip area. Like riding jackets, riding pants are made using abrasion resistant textile / mesh or leather. So even in case of a fall, armor in pants would take the first impact and in case of small crash, there would less tear off.
Typically riding pants will also have reflective piping to make you more visible to others. They will also have ventilation panels, water resistance and thermal insulation liners depending on the model.
Riding pants in India are typically available as Mesh / textile pants, touring pants, or riding jeans.
Brands like Royal Enfield, TVS, RS Taichi, Raida, BBG, Rynox sell riding gears like Jackets, pants, gloves etc., so you have lots of options.
