I’m touring the Alps this summer and the panniers that I have are 20l each with small entry points and have to be removed from the bike for safety (soft panniers). This Tail bag is exceptionally well made, it holds its shape and fits to any of my bikes with no fuss. Easy to remove and carry and with 65l storage it has made my panniers redundant! More than enough for a 2 week tour without scrimping on what I’m packing. Really impressive bit of kit!
