The TKS stands for Tech-Kit Sling, because inside the padded back-panel, there's a hidden belt; pull it out, snap the Magnetic V-Buckle and you've got a fully-functional Sling Bag. The TKS brings new meaning to the word versatility. The outside pocket is a great spot for your keys, which have a home on the included Maglock keychain. There are two storage compartments inside, each one merits explanation. The elastic mesh pocket is a perfect spot for a packable windbreaker, while opening the Hypalon pull-tab on the magnetic buckle reveals the accordion organizer. The accordion has six separate pockets inside to keep each of your items in its own secure, easy to find spot. If your phone supports wireless charging, place the charger in the last pocket - if you want to use USB instead, there's a special laser-cut and bonded cord pass-through hole. The TKS is made from 500D Cordura Multicam, and includes YKK Aquaguard zippers and proprietary bond-stitching to keep your gear dry. All of the components are laser-cut for high precision. And it's built to last.
