Efficient jeans are still hard to find. Conventionally grown cotton requires more pesticides to grow than any other crop. The more efficient method is to grow organic cotton or hemp. The surf company Reef makes some good organic cotton jeans, like their Heritage Jeans (shown above), their Philosopher Jeans and Heritage Cords. The outdoor clothing company Patagonia offers organic cotton jeans. Hemp is the most optimal material with which to make jeans, but few hemp jeans are available. You can find some at Hempest.
