Form and Function

We’ve always been frustrated with the lack of lightweight storage cases for crampons. It’s true that crampons with sharp claws require somewhat sturdy storage. But the available options were too heavy and bulky, taking up too much space when we had to take the crampon out and put the cases in our backpacks, taking up too much space on already gear-heavy winter hikes.

The right L Size pack is a discontinued color.

So we’ve created a stuff pack that’s sturdy enough to hold your crampons, but lightweight and compact. It’s also super easy to open and close even with your gloves on. The smaller version is for storing just a pair of crampons and the larger Pack holds crampons as well as snow spikes and snow pegs all in one pack.

Cold-resistant Velcro

In cold weather, zippers and buckles can freeze, and it can be difficult to open and close them with gloves on. That’s why we use Velcro tape, which makes it easy to take out tools even with gloves.

Eyelets for more flexible use

We’ve added small eyelets in all four corners if you want to attach the Stuff Packs more securely to your backpack with bungee cords or small carabiners. You can also attach a length of cord to two of the eyelets to make a small simple shoulder bag.

Daisy chain for secure attachment to the backpack

A daisy chain on the back allows for secure attachment to compression straps or other parts of the backpack.
