Keep the outing list selective
Lay out the essentials for the type of day you expect to use it, then compare the open bag dimensions. A 20-liter label is a volume claim, not a guarantee that every rigid object will fit through the opening. Look at bottle storage and access to small items if those will shape your experience.
Check the folding and weather details
Find out whether it folds into its own pocket or uses separate storage, and measure that package against the space you have in your main bag. Water-resistant wording does not identify a waterproof closure system. Ask about fabric and seams if rain is a regular concern, and use the actual product instructions for care.
Compare it with your actual load
Put this model beside another backpack in the comparison tool. Missing figures stay marked as unknown, so you can see which measurements need checking before you buy.
