The PhotoSport PRO backpacks are rugged and designed for all weather conditions and feature the PhotoSport's signature V-shaped exterior. Designed for extreme outdoor photo adventures, the PhotoSport PRO backpacks offer the carrying capacity needed for multi-day hikes and backcountry trips without compromising comfort and modularity, while keeping your photo gear safe and secure. This professional backpack line is offered in two sizes: 55 and 70 liters. Both models are designed to hold a full-frame mirrorless or DSLR camera with vertical grip and 70-200mm f/2.8 lens attached, plus two additional lenses or a portable camera drone and accessories. Both bags are designed to easily carry hiking and camping essentials for a multi-day trip such as sleeping bag, tent, food storage containers, jacket and trekking poles. Each version can be purchased with two different shoulder straps. The S-M straps are designed for smaller, narrower torsos. The straps therefore have a slightly stronger curve and are shorter. The M-L harnesses are designed to better fit larger, stronger torsos. The straps are longer and less curved. The foam is strategically perforated for maximum comfort while carrying. The backpacks come with a modular GearUp PRO XL, which has both front and rear access and serves as a removable camera compartment, providing additional protection from shocks and moisture for equipment. If you love the outdoors, you're sure to care about the environment, which is why the PhotoSport PRO backpacks fit seamlessly into Lowepro's Green Line? label, where all carrying solutions are made from recycled fabrics. Each variant is provided with a loading bar display that contains information about the percentage of recycled fabrics in the product. The PhotoSport PRO backpacks are made from 85% (BP 55L) and 86% (BP70L) recycled* fabric, while the GearUP PRO XL and L are made from 50% and 47% recycled fabric respectively.
