If you want to narrow down your choice to a backpack suitable for long rides, the Osprey Syncro 20 Coal Grey leaves nothing to be desired. It offers 20L of volume in a compact, bike-oriented design, so you can take everything you need – spare layer, tools and supplies – without being limited by a backpack. AirSpeed ventilated back system and integrated raincoat increase comfort in warm and humid conditions; The shoulder straps are shaped for better stability. The arrangement of the internal pockets is practical: a dedicated place for a hydration tank, zipped tool pockets and pockets on the waist belt for quick access. The fabrics used are bluesign® approved and DWR treatment PFAS-free, which is an important technical detail. Muted Coal Grey easily complements cycling gear and everyday wear and suits those who prefer a clean, functional look.
