This lightweight backpack is ultra lightweight at only 12.5 ounces. This is a great backpack for outdoor activities where you don't want to carry anything else with you, and want a lightweight hands free option that has superior breathability for your unit. Fits both the standard & extended battery. The backpack has a zippered bottom for easily changing your battery and a pad that rests at the bottom for when a single battery is used & can be taken out when the extended battery is in use.
