Introduction

Form and Function

We’ve long been frustrated by the lack of lightweight storage solutions for crampons. While it’s true that crampons with sharp spikes need sturdy storage, most options on the market are overly heavy and bulky. Once the crampons are in use, these cases take up precious space in our already crowded backpacks—especially on gear-intensive winter hikes where every bit of room counts.

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.

Size S (left)/Size L (right)

MINI – S size Stuff Pack

Secure to the top strap utilizingthe daisy chain.

THREE – L size Stuff Pack

In addition to the top strap, the side compression straps can be utilized for the THREE with the daisy chain.

Cold-resistant Velcro tape

In cold conditions, zippers and buckles can freeze, making it difficult to open when wearing gloves. We’ve opted for Velcro tape for easy access.

Grommets

Grommets on all four corners for versatility. Secure to a backpack with bungee cords or use as a simple bag.

Daisy chain

A daisy chain on one side for secure attachment.

Material

X-Pac VX21

X-Pac VX21 is a highly durable multi-layer fabric with excellent strength and waterproof performance. It combines an abrasion-resistant 210-denier nylon face fabric, a waterproof polyester film in the middle, and a 50-denier polyester taffeta backing, reinforced with tough black polyester X-Ply yarns arranged in a diamond pattern.

Combined with its hydrostatic waterproof construction, this layered structure provides excellent durability and reliable protection from water.
