For a comprehensive solution to your daily or travel needs, look no further than this versatile backpack. Not only does the pack do everything it should — including a roomy main compartment, adjustable ergonomic straps, and waterproof construction — but it also protects against the unseen. A patented Silent Pocket Faraday cage lines the pack, so your devices are safe from anything that might try and steal your information or identity. A 2.5L removable dry bag with the same protection is also included, for even more protection and functionality.
