We believe the ideal pack should be exactly what you need, and precisely nothing more.

Developed over the course of more than 3 years and refined through more than 35 prototypes, The Tupilak is arguably our finest all-round pack.


Designed with the principles of alpine minimalism in mind, this durable, highly weather-resistant yet lightweight climbing and mountaineering pack is perfect for summer alpine and winter climbing on the steepest lines. Every aspect of design and functionality has been individually tested and assessed by us, our pro partners and a hand-picked group of professional mountain guides.


Only what you need

In October 2021, Tom Livingstone and Matt Glenn climbed a major new route on Tengkangpoche’s North-East pillar in Nepal, after spending a total of 7 days on the route.


In this video, Tom Livingstone takes us through what essentials he took with him in his Tupilak pack on the route.



What size of pack you choose is personal.


But whether you want the smallest pack for accessible ice-fall climbing or multi pitch rock, the most versatile for lightweight summer alpine ventures or the largest for winter alpinism and remote multi-day objectives our packs have been optimised to carry all the essentials and carry them well.


That means each and every one of our alpine climbing packs has been designed to accommodate the type of climbing kit that you’d be taking within its main body: ropes, harness, climbing rack, helmet, and spare layers; and dependent on your objective also tailored to accommodate additional layers or overnight bivouac gear. Ice tools can be quickly and efficiently stored outside whilst smaller items needed more readily such as a head-torch or food can be stored in the internal floating pocket which is accessible from both inside and outside the pack.


We quote our pack sizes in litres. Every pack is individually filled with hundreds of tiny non-compressible plastic balls each 20mm in diameter. These are then removed and poured into a large measuring cylinder to calculate the packs total volume. We choose to do this with the cowl top fully closed, the internal roll-top closure securely sealed and not ‘overstuffed’. If you want to leave the cowl or roll-top open and overfill your pack then go ahead but the volumes we quote are their optimally packed main body volume. The alpine environment is far from black and white and technically easy but exposed terrain is no place for an overloaded, unstable pack.

Designed with the principles of alpinism in mind...

'Developing the Tupilak packs was a huge project. We had a clear idea of what we wanted, but at times it was a real battle: we made more prototypes and over a longer period than any other project, changed the fabrics we’d chosen multiple times, and had countless discussions with testers putting protos through their paces. It was worth it though: the end result is a genre-defining series of packs that are now well proven on hard routes and peaks all over the world.'

Constructed with an uncluttered Diabolo profile – an hour glass shape that maximises load stability and packability; every one of our packs is marginally wider at the base and at the top, improving stability and making stuffing in gear easy, even when you’re rushing against the onset of nightfall.


It will also stand upright of its own accord. At the same time the main body of the pack is gently tapered at its centre, the pack is more streamlined and mobility is improved.

Custom made

At the heart of any lightweight, durable, functional and weather resistant pack are its materials. How a pack carries, how a pack copes with abrasion, how it responds to heavy rain or snow and how you are able to interact with it, open it, attach things to it are all directly affected by the materials and components it is made from.
