This original WE design is now SOLD OUT and undergoing a re-vamp. Please be patient! Here you go anyway... The Slipstream was inspired by our own cycle commuting requirements. It has remained a favourite. The horizontal main zip and sloping top panel give this bag the best possible water-shedding, weather-resistance. Immediately you start using this pack you will discover its convenience: Push back the unzipped bag canopy and the entire contents can be easily viewed and accessed. Selecting from the contents is a breeze. With more than 20 litres usable capacity this rugged daypack is ideal for just about every trans-urban, work-day journey.
