• Create laptop cases that last a lifetime... and stand behind them.  All Brenthaven cases are made of the finest, most durable materials and come with their legendary lifetime guarantee.
• Reduce what they can... Recently, they changed their packaging strategy and eliminated the use of over 100,000 boxes; they use recycled paper and soy-based inks to make all their marketing materials; and they give employees financial incentives to walk, bike, carpool or take public transportation to work.
• Offset what they cannot... Last year, through their investments in carbon credits, they offset over 50% of their carbon footprint.  Their ultimate goal is to become a carbon neutral or carbon balanced company. They call it Zero Impact.
