Great for light touring or commuting, the Ortlieb Seatpost Bag delivers excellent protection from the elements and convenient mounting when it comes time to ride.

  • Made of tough, long-lasting coated Cordura® nylon fabric; bag opening rolls down to protect and secure load and closes with integrated elastic cords and hooks
  • Bag is rated to IP64 protection, meaning it is dust-proof and protected against splashing water coming from all directions
  • Ratcheting seatpost clamp can be fine-tuned to fit a variety of seatpost diameters (25.4 - 34.9mm), and allows bag to be quickly and easily swapped between bikes
  • External compression cords quickly and easily adjust to secure light, bulky items— like a compressible jacket— to the outside of the bag
  • Internal organizer pockets help keep smaller items easily accessible
  • 3M Scotchlite™ reflective detailing increases your visibility in low light
  • Maximum load capacity is 5 lbs. 8 oz. (2.5 kg)
