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.

The seat pin locking straps, 3 point attachment system and roll top closure all work together to keep twist and sway to a minimum so you can focus on the trail ahead. You can squash the bag down to around 8 litres in size or you can max it out to around 13 litres. In practice, a regular Koala will hold a lightweight down sleeping bag such as our PipeDream 400 and Filo down jacket with ease.

Small Koala takes all the great features from Regular Koala and shrinks them down into a smaller 7 litre size which demands less from your tyre clearance.

If you ride a smaller frame size or enjoy the comfort of rear suspension you may find the Small a viable alternative to our Regular Koala, 5 cm smaller in depth which means that you need less clearance between your seat and your tyres.

Made from VX21, it is durable enough to be dragged through bushy singletrack, water resistant and shiny enough to deflect most of the mud, and reinforced with strong nylon webbing straps to keep everything in place.

From time to time especially on rougher surfaces as the contents of your Koala moves about and settles you will have to tighten the straps now and again to minimise its movement on your saddle.

The seam of a Koala are not taped, so in extremely wet conditions your kit may still get wet. We would recommend using a Airlok Tapered drybag if you have to keep something dry. Check out the Airlok range of lightweight drybags.

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.

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.
