Ideal for day hikes in the sun, it features a very innovative ventilated back system that allows air to circulate to prevent the user from sweating on their back. With a tensioned mesh that follows the contours of the body and distributes the load evenly, it remains comfortable from the first moment to the last. Compact, it helps keep the weight to a minimum and the load stable while being incredibly tough thanks to its 140D ripstop nylon that can withstand wear.
