Look, I like big ol’, voluminous backpacks for hauling my gear as much as the next Gadgeteer. But sometimes you only need to carry minimal gear and want to be subtle and stealthy, like a gear ninja. For those missions, the crowdfunded Betabrand Under-the-Jack Pack might be essential. Betabrand designed this ultra-slim backpack to literally fit under a jacket without anyone being the wiser. Mind you, it doesn’t hold a lot. After all, it is only 1.5 inches thick and with a small footprint. But the Under-the-Jack Pack is available in two sizes to fit 13-inch or 15-inch laptops and both include a large zippered compartment for a laptop and notebook as well as a small zippered compartment for a charger, smartphone or other small accessory. Padded shoulder straps and a padded backside strap round out the design. Priced at $68. Sneak over to Betabrand for more info.
