Before I start the review, I would like to say that I am obsessed with backpacks. I have been doing photography for about 12 years, I have tried many backpacks. I currently have Onemo 25 l. and Onemo 2 35 l. the Onemo version 1 was perfect, but PGYTECH, I don't know how they did it, but made the Onemo 2 even more functional than version 1. optimization of space, infinite pockets and compartments, designed for photographers and videomakers. Sometimes I use the Onemo 25 l as my only travel backpack, half backpack with clothing and half for camera and lens. Comfortable, incredible ergonomics. I have seen and reviewed hundreds of reviews of other backpacks, something was always missing!! Pgytech has it all!! I sincerely would like to thank this company for being so helpful to photographers.
