This 28-liter backpack features fixed carrying straps and is resistant to any type of weather. The TOUR28 UL has XPAC fabric on the front panel to make this Ultra-light Airbag even more resistant during diagonal carry.  Designed for "Fast & Light" backcountry skiing enthusiasts, the TOUR 28 UL REACTOR follows you efficiently in your most intense physical exploits without you having to miss out on the REACTOR technology. This is the lightest, most compact and efficient airbag system on the market.
