Stay nice and cool on all of your journeys with the Ventila Backpack Ventilation Fan. Compact and effective, this fan rids of the always dreaded back sweat from carrying your bag. The Ventila is totally minimalist to work with virtually any bag. Securing in place along the bottom of your bag, the Ventila is also invisible while you’re wearing your bag. Inside this handy device is a powerful DC blower. This pushes the air between you and your bag to allow the hot air to escape and, thus, keep you cool. The shape of the Ventila is designed to conform gently to your bag for all day use. In addition, the magnetic attachment system means you can swap it from bag to bag with ease. It’s also small enough to store away easily when not in use. With variable fan speeds, you can always feel relief with the Ventila.
