How to Pack & Attach
- Pack your heaviest items (like tools or a bikepacking sleeping bag) at the bottom, closest to the seatpost, to maintain a low centre of gravity.
- Squeeze out excess air, then tightly roll the top closure at least three times to ensure a waterproof seal.
- Clip the roll-top buckles securely.
- Wrap the wide, non-slip Velcro strap tightly around your seatpost.
- Thread the two upper straps over your saddle rails, clip them into the buckles on the bag, and pull them as tight as possible to eliminate sway.
- Attach your rear light to the built-in loop for added visibility.

Brilliant piece of kit for the Welsh weather. I've used this on several wet commutes and everything inside stays bone dry. The 500D PVC is tough as old boots and washes down easily.
Finally, a rack-free solution that actually works! I use it on my hybrid bike to commute across London. It easily fits my work clothes and shoes, and the anti-sway straps mean I barely notice it's there.
Really solid bag for the price. I managed to fit my compact bikepacking sleeping bag, a bivi, and spare clothes for a weekend in the Peaks. Only giving 4 stars because you really need to make sure you have enough tyre clearance if you ride a smaller frame.
Excellent alternative to a sweaty backpack. The attachment system is very intuitive. I've had it fully loaded on gravel tracks and the stability is impressive-no annoying wagging at the back.
Delivery was incredibly fast, arrived the next day. The build quality rivals bags twice the price from the big adventure brands. The roll-top closure is totally watertight against road spray.
Great waterproof performance and holds a deceptive amount of gear. Just be careful how you pack it-if you put wide, bulky items right at the front near the seatpost, it can rub your thighs slightly. Pack it right and it's perfect.
At Bikepackin, we believe that carrying gear on your bike shouldn't require heavy metal racks or sweaty backpacks. Founded by a group of all-weather UK cyclists, we set out to create a practical, rack-free solution that actually stands up to the British elements.
We grew tired of premium adventure brands charging a fortune for complex setups, and budget options that soaked our spare layers at the first sign of a puddle. That's why we developed our signature 13L waterproof saddle bag-a straightforward, highly durable seat pack designed for real-world riding.
Whether you're dodging potholes on a damp Tuesday commute, escaping onto Welsh gravel trails for the weekend, or packing a lightweight bikepacking sleeping bag for your first overnight tour, our gear is engineered for stability, simplicity, and 100% weather protection. No racks, no fuss, just dependable storage for the road ahead.
