Seat Bags

Get ready for your next bikepacking adventure! As a key item in your bikepacking setup, the ORTLIEB Seat-Pack comes with Velcro straps to enable convenient and secure mounting to your seat stem. Projecting backwards from the seat stem, your Seat-Pack also serves as a rear fender. The spacious, waterproof Seat-Pack keeps its contents (e.g. an extra set of clothes) safe and dry. Depending on how long you plan to be away and your Seat-Pack model, you can conveniently adjust the volume of your pack from 8 to 16.5 liters by adjusting the roll closures on the sides. An additional valve allows you to quickly and easily compress your soft gear for a more compact fit. Your Seat-Pack also serves as a replacement backpack when you’re out on a day trip, no matter whether you ride a hybrid bike, a mountain bike, a road bike, or an electric mountain bike. Thanks to its elastic drawstrings on the top, the 16.5-liter model offers additional space for items you need to be able to access quickly. This model needs only 15 centimeters of space on your seat stem. FURTHER FEATURES: - Reinforced fabric at all points of contact to the seat - Vertical daisy chain for rear light - Also suitable for carbon seat stems - Lightweight design - Four 3M Scotchlite reflectors available for full extension

We set out to create the most stable, low profile mounted, feature loaded, waterproof seat bag available. The Spinelock seat bag checks all the boxes. The Spinelock integrates user tested and approved features like a one-way air purge valve, rear light slots, loop and bungee deck, and an external plastic bottom with a new patented attachment system. Stability was the driving element in the design process. If you want something you can pack and forget, the Spinelock is your seat bag. There are two size options, neither of which sacrifice features for capacity. The smaller but largely versatile Spinelock 10L maximizes your carry with minimal tire clearance and provides a generous amount of waterproof storage with additional space on the external corded deck. . If you are going on a long expedition or carrying cold weather gear we recommend checking out the Spinelock 16L. How it works: - The Spinelock stability system consists of three components: the saddle clamp, seat bag mounted "Spine" baseplate, and pin. - A low profile, high strength, forged aluminum clamp works in combination with precision IGUS bushings to form the pin interface. Twin forged upper arms, fastened by Torx-25 bolts, rotate into position above the saddle rails for easy mounting. - Resembling a spine ramp familiar to skateboarders, the "Spine" baseplate is made of an impact resistant UV-stabilized nylon and is integrated to the seat bag surface. The plate features two mounting positions to accommodate seatpost setback and saddle adjustments. To connect the bag, you simply line up your selected mounting position to the seat mounted clamp and slide the pin through the aligned holes. Attaching the side compression straps to the wings of the clamp fixes the pin in place and you're ready to ride!

An additional valve allows you to quickly and easily compress your soft gear for a more compact fit.

The Seat-Pack is available in two sizes. This model needs only six centimeters of space on your seat stem. That's why the more compact model is ideal for smaller frame sizes, full-suspension bikes, and adjustable seat stems.

The Shrew is our smallest seat bag yet! Updated for 2021 to include a rear stabilization strap. The Shrew is built for big day rides on any terrain: gravel, singletrack, road, snow, whatever. The Shrew carries spare clothing and gear for the long haul with ease. It packs a mighty 2.25L capacity and weighs just 5 ounces. Mounting only to the saddle rails gives the Shrew maximum versatility and a near universal fit to any bike. Compatible with any seat post—dropper, suspension, aero, or high setback seat posts are no problem, the Shrew fits them all! Scaled down from our larger seat bags, the shrew features independent rail straps with added hypalon wings that wrap the upper saddle rails. The attachment straps connect to a fiberglass stay stiffening the bottom of the bag for compression. This system gives the bag great stability in a small package. A roll top opening provides fast and simple access to your gear. FEATURES - Roll down closure allows bag to expand or compress in volume - Revelate exclusive RevX-PAC panels that are two-times as abrasion resistant as standard VX material. - Indie-Rail attachment system provides maximum stability without added hardware. - Fiberglass stay - Carbon seatpost friendly - Made in the USA with domestic and imported materials SPECIFICATIONS - Weight: 5 oz / 142 g - Volume: 137 in³ / 2.25 L - Materials: Dimension Polyant VX-21 with abrasion resistant finish.

Similar to the original MATTONE, a high friction Hypalon strap with BOA Closure completes the package. Making more than 15x the power of Velcro, the BOA Closure uses a ratcheting mechanism that will not creep or loosen even under the most extreme vibration and impact. This ensures the MATTONE will remain 'high and tight' under your saddle until you need to access it... no swinging, swaying, or rattling... ever
