Welsh fire track, big Scottish mountains... 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.

Excellent & Versatile

I've used the Possum on my adventure bike on every ride from 5 hours jaunts on local trails, to overnight bivvies to ultra racing and it's never come up short.

For my usage, it usually gets used to hold spares, tools and electronics. On a recent 2200km MTB bikepacking ride I had it loaded with my powerbanks, cables (the cable port on the top is a great feature), tubes, gas, tyre levers, chain links, spoke key, disc pads, chargers and even some extra food and it's behaved perfectly.

The glow in the dark zip toggles make fumbling for stuff in the dark easy and it's so waterproof that in my lazier moments I've left it on when I clean the bike.

An awesome product.
