Osprey says about the Sylva 20
Spacious with plenty of pockets, the women’s-specific Sylva 20 is the answer to bringing lots of layers, tools and food for a long day in the saddle. The shoulder straps on this pack are curved to fit the shape of your body when you reach for the handlebars—meaning it maintains superior stability over the most technical terrain. An AirSpeed backpanel offers maximum airflow and a removable hi-vis raincover protects your gear in wet weather.
