Go Deeper Into the Backcountry!. Get deeper into the backcountry with the BackLight Elite 45L backpack. 45 liters of available space provides ample room for both camera gear and adventure equipment, such as a length of rope, ice axe, snowboard/skis, laptop, tablet, and of course, a tripod. Weather-resistant zippers and materials protect your gear when trekking in the elements. And like the other BackLight backpacks, rear-panel access adds security when traveling since your camera gear is protected behind your back. Color: Gray.
