Berghaus Ladies Twentyfourseven 15 L Rucksack.
The Ladies TwentyFourSeven 15 litre Daysack has a brand new design this year! It packs in lots of features that most bags this size leave out, such as an internal organizer, walking pole attachment, detachable waist belt and hydration system compatibility.
This little daysack is named TwentyFourSeven because it's designed to be tough enough to be used all day every day.
