What to Compare Before Buying

Who This Product May Suit
This backpack may suit cyclists who want a 25L bag for commuting or work and prefer a design that combines visible detailing, organised storage and everyday carrying comfort.
It is also relevant if you want a single backpack for items such as clothing, work essentials and laptop accessories, rather than a minimal carry option.
Care, Cleaning and Storage
A water-resistant backpack is best checked and stored with its finish in mind. Keep the zips and fabric clean enough for regular use, and allow the bag to dry fully if it becomes damp.
Before You Decide
Confirm that 25L is the right capacity for your load, and check that the hi-vis and reflective detailing matches how you plan to ride. If you need stronger weather protection than a water-resistant finish, compare a different option before choosing.
