The Tenba Axis 20L Backpack (Black) is modeled after military backpacks, with a comfortable and secure design made for carrying your mobile photo studio. Its main compartment is spacious, and features an adjustable partition system which is capable of fitting a DSLR with a 300mm f/2.8 lens, five to seven other lenses, and flash or a folding drone kit. If the user works with mirrorless camera systems, the Axis 20L can fit up to five to seven lenses, a camera, a flash or a folding drone kit, and a backup camera. Its easy-to-access main compartment is acessible using a rear-facing zippered panel, which has a 180° downward opening, and two additional zippered openings, allowing you to access items closest to the top and side with ease. Rotating the Axis 20L Backpack from the user's back to front, with its side facing upward allows you to be able to open the bag without having to fully remove it. MOLLE-compatible loops are distributed across the front panel, as well as the side opening. These MOLLE-compatible loops allow you to attach the MOLLE accessory pouches and containers, which include Tenba Tools lens capsules, battery pouches, and memory card wallets (Available As Separate Purchase). The MOLLE-compatible loops include reflective stitching that increases your safety by keeping you visible to traffic in low-light conditions. The front panel also unzips to reveal multiple pockets for organizing your accessories, such as: hard drives, a smartphone, pens, notebooks, or a map. The top zipped opening includes a small pocket for items that need to be accessed quickly, such as portable batteries, camera filters, or other small items. Along the inside of the rear-zippered panel is the Axis 20L Backpack's 15-inch laptop sleeve which features a touch-tab retaining strap. The Axis 20L Backpack can be carried by its built-in top handle, or by its padded shoulder straps, which are adjustable. For heavier travels, this backpack's removable waist belt transfers weight to the hips for comfort, while the sternum strap helps keep the pack secure. Along the front of the Axis 20L Backpack are two MOLLE-compatible compression straps, which are able to hold and secure a tripod, monopod, or trekking pole, while a large side pocket along the right side can hold a water bottle or another similarly sized item. The Axis 20L Backpack also includes a seam-sealed cover for use under heavy rain, making it weather-resistant.
