If you prefer mountain biking in long pants, the Pearl Izumi Launch Trail Pants are just the one's for the job. The Cordura face fabric is tough and rugged to hold it's own against grabby brush, water resistant to protect you from mud and rain, and has a nice 4-way stretch for unhindered movement. These pants add some nice warmth for biking in colder weather, but are light and breathable enough to wear on warmer rides, hikes, or our to the climbing crag as well.
