The LEX is a bionic wearable that enhances posture, comfort, and life. It is designed to let you relax anywhere with a perfect sitting posture and protect your shoulders while on the move by making the backpack feels almost weightless. The LEX weighs a little more than 1 kilogram so it can be worn comfortably at all times. In just a few steps, the LEX turns into an ergonomic chair built to withstand up to 120 kilograms (264 lbs) of weight. Immediately feels relaxed as your back straighten and breathing becomes easier the moment you sit. The longer you use the LEX, the posture improvement will give you long-term physical benefits.
