Paintball pants should be one of the first "big buys" you make as a paintball player. These are extremely important, and I guarantee they will help you play more comfortably. In a good pair of paintball pants, you will want to look for a combination of padding, flexibility, and above all comfort. I recommend lighter weight pants personally. They will allow you to run around with more of a natural feeling. Heavy pants can become a burden, especially on a long hot day.
