Bikes are a great way to get from A to B, but they don’t have much in the way of on-board storage. The solution is Ortlieb’s range of bikepacking bags, including their nifty Seat Pack. Available in either 11 or 16.5 litre capacities, it’s the perfect size to stow a set of spare clothes, mounting easily and securely to your seat stem. In this position it also serves as a rear fender, protecting you from mud and trail debris. A fully waterproof design keeps contents safe and dry, while adjustable roll closures and an air valve allow you to cinch or expand the volume from 8 to 16.5 litres or from 7 to 11 litres. The larger model needs just 15 cm of space on your seat stem, while the smaller needs only 6cm (ideal for smaller frame sizes or full suspension bikes).

Life in the great outdoors is unpredictable, which is why it’s wise to be prepared. Basically, if your adventure goes from dry to downpour, you want your kit to stay safe and protected. Ortlieb’s durable, waterproof bike bags and backpacks are the ideal solution.
The first Ortlieb bag was invented in Germany in 1981, after founder Hartmut Ortlieb got back from a very wet bikepacking adventure in (you guessed it) Southern England. Inspired by tarpaulins he’d seen lashed on the truck beds of lorries, he fashioned a pair of bike panniers from red truck tarp, which he stitched at home on his mother’s sewing machine.
A year later he founded his own company, buoyed by early success and positive feedback from friends. In the following years, young Hartmut came up with a series of innovations that would define the modern drybag, using high frequency welded seams and roll-top closures. He even developed the first self-locking mounting system to attach panniers to bike frames.
Today, Ortlieb remains the first and most trusted choice for adventures and expeditions on land or sea – a brand name synonymous with waterproof protection and super-tough, outdoor-ready gear.
A great product - clean and simple in design - built well and robust!
