Endless sandy beaches, the technical trails of the Scottish Highlands: no two terrains are the same. Although your bike may change over the years, some things will stick by you no matter where you go. Possum is one of them.

Possum ½ frame bag sits in your front triangle to provide stable, secure, and swing-free storage for carrying your heavier items without affecting handling too much. It’s shaped to fit modern MTB geometries with lower stand over heights and the ½ bag design gives you space to run bottles and cages. 

The tardis-like Possum is spacious for its size, with a main compartment for bigger objects and a smaller accessory/document pocket on the other side to keep your wares organised. The front-facing cable port keeps things neat and simple when you're running wires to your dynamos and charging your light batteries on the go on those longer bikepacking excursions. 

Constructed from lightweight and abrasion resistant fabrics in our UK factory, Possum is made to cope with demands of travel without adding weight to your set-up. Like all our UK-made bikepacking luggage, it’s backed up by our 25-year Alpine Bond warranty.  

A webbing ladder offers endless fastening points; simply cut the VELCRO® strap provided to size.

"Is it waterproof?" 

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

Chris Bike Pack
Great bag

Excellent bag. Well made and thought out design. Maybe a touch over priced.

Bounced it over every Belgian cobble I could find.

Bought this for a few days exploring the Tour of Flanders routes over every cobbled section I could find in the howling rain. The bag was flawless, unlike the rider who still has a cobble shaped bruise on the hip. Took all my tools, pump and 4 Pan au Chocolat with loads to spare.
