Whether you’re traversing rolling hills of the Peak District, exploring the Lake District mountains, or bouncing from bothy to bothy in the Scottish Highlands… the adventurous and ever-dependable Koala is a trustworthy companion. 

Koala attaches beneath your saddle to provide you with secure and light storage with an impressive capacity.

Koala is at its most stable when attached to the Exo-Rail, which reduces sway and increases stability. Attachment is quick, simple and secure with a slide-on, slide-off sleeve and stabilising saddle rail strap. If you don’t have an Exo-Rail, you can partner up the saddle rail strap with velcro straps and the handy webbing ladder to attach it without. If you're buying the Exo-Rail and Koala together, head over to our Exo-Rail / Koala 13 bundle for a bit of a saving!

Koala has a pared back design to make it incredibly spacious for its size and weight. Available in 13 L capacity, it’s spot on for packing your bulky, light, and compressible kit when off bikepacking (think sleeping bags and clothing). Koala also comes in 7 L capacity, which is also dropper seat post compatible.  

Roll-top closure and compression straps keep your cargo compact and portable and ensure stability when the bag is less full. 

When cycling in a downpour, we recommend using a drybag with your Koala for added protection.  

"Is it waterproof?" 

Although highly weather resistant, this product is not fully waterproof due to its stitched construction. If you are carrying valuables or electronic equipment, make sure to put it in a dry bag.

Very robust saddle bag

Easy to attach! Sway is very minimal, I barely notice it is there, even when it is fully loaded.

Great Product, not so great customer service.

After receiving my Koala 13 seat bag and matching Fuel Pod 22 in Matching Cordura Jaffa I was pleasantly surprised at how good the build quality is on both items... My only disappointment is that they don't do any of the handlebar bags to match, and trying to find out this from customers service team has proved unsuccessful, with no reply to my enquiry through the online form... It does state that they reply to every email?
