There are hundreds of DSLR backpacks on the market, but the Ikigai Rival sets itself apart by using a removable padded cell to hold gear--essentially the Rival is two bags in one. Why the extra cell? The bag is designed to be repacked quickly, so it's easy to only bring the gear you need for that particular shoot. By purchasing a second cell, you easily can swap out your portrait gear for your wedding gear, for example. That makes the system ideal for photographers that have a lot of gear that they don't use for every shoot, since you don't need to repack the bag every time.
But besides the unusual cell design, the Ikigai Rival holds up as a solid, sturdy backpack. Along with the cell, which can fit a DSLR and up to 7 lenses for the medium (the large can fit up to nine), there's also a padded laptop pouch, smaller pockets for accessories, side pouches and tripod straps. Access to the gear is from the back of the pack, so you have to take the bag off to get your gear. The Rival isn't the first to use this type of design, which helps deter theft, but the Rival also has a quick access pouch at the top which is much more convenient. The bag is also pretty comfortable to wear with thick padding on the straps and a vented back panel.
