Made in our own UK Workshop Koala is one of the lightest high capacity seat packs you can find. We have designed the geometry of the straps and added an additional locking strap that runs around your seat rails. This provides enhanced stability and prevents slippage due to vibrations, especially when your Koala is not fully stuffed.

Webbing colour change

For a short time production of this product will be with black webbing instead of the grey featured in the photography. This is a temporary measure until we take delivery of grey webbing next month. If you absolutely need grey webbing please let us know when you place your order using the notes field. This may delay your order.

Practical spacious saddle bag

purchased a Koala Saddle 13l bag for a 700km trip (yet to do) This bag is deceptively big and will just about fit the bare essential clothes in for the journey, (3 sets of bib shorts, cycle tops and dry clothes for the evening it's tight but they fit. I've tested it out on several commutes to the office and it not only prevents mud from the bridal way spraying up my back, it ensures my work clothes arrive dry and dirt free, which is fantastic as I hate cycling with a rucksack.

I'm planning on getting the Tivaro 13l handlebar bag before I set off on the ride at the end of August and then hopefully next spring the Camino Al.

Customer service was great, helpful and clear, definitely recommend.

Koala review

Have had this bag for over a year now with moderate usage.Fits a lot of stuff in but straps are quite fiddly and top buckle often caught under saddle.Light for its size.Would give it better rating but shows more wear than expected from structure material coming through outer given it hasn't been given a hard time.


CTC - Seatpack Test - Koala

Dave tests seat packs for touring cyclists and finds the Koala the lightest, most versatile for capacity and stable seatpack.

Well designed and lightweight bag that's ideally suited to off-road touring.

Koala seat pack questions answered

Stuart Wright of Bear Bones Bikepacking gets his hands on a Koala seat pack and takes it for a 100 mile round trip.

A few weeks ago I got my hands on a 'Rough cut' pre-production Koala and last week took it on a 100 mile ride to the BNO in the Peak District and back again.
