Modern rackless bike luggage made from waxed cotton, a natural and traditional material, right here in our UK factory. Wet waxed cotton looks great, feels great and is entirely functional thanks to the wax coating which gives the fabric its water resistant coating.

Koala attaches beneath your saddle. It is at its most stable when attached to the Exo-Rail, which further 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, or you want to keep things as light as possible you can attach it directly to the saddle rails with the straps provided. 

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 (think sleeping bags and clothing). Koala also comes in 7 L capacity giving more clearance for a dropper seat post.  

A 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 inside your Koala for added protection.  

Whether you’re traversing the rolling hills of the Peak District, exploring the Lake District mountains, or bouncing from bothy to bothy in the Scottish Highlands… Koala plays an essential part in your load carrying system. Lightweight, secure with an impressive capacity.

Designer Notes

Wax cotton was used as a performance outdoor fabric for years before all our modern textiles were invented. Innovation is great but sometimes it pays to look back and see what has worked over the years… especially if you want to do it in style. - Hebe

Product Care Information

Caring for your gear is all part of the adventure. This bag is made from wet waxed cotton, you will need to rewax your bag every so often so that it maintains its water resistance. We recommend rewaxing every 12 months, or sooner if you notice your bag isn’t repelling water as it should.

First, make sure your pack is clean. If it isn’t clean just sponge it down with cold water and brush it lightly to remove dirt or grit. If it’s really dirty (these things happen!) hand wash it in cold water with Nikwax Tech wash. Don’t dry clean or wash your waxed cotton pack.

Now your bag is clean…

Spray Nikwax Wax Cotton Proof onto the outer of the bag, paying close attention to the seams and area s of high wear. The waterproofing will look opaque and white, don’t worry - it will dry clear!

Once you’ve sprayed the bag, rub the cotton proof into the fabric and remove any excess.

Buff the bag.

Let the bag hang dry in a well ventilated area, avoid humid places! It may take a coupld of days to completely dry.

Bob’s your uncle! A rewaxed bag ready for your next adventure!

If you don’t fancy rewaxing your own bag, you can send it off to Rewax and they’ll do it for you. Head over to rewax.co.uk for more information.​
