project 321 - essential kit


It's no secret Mt Everest is an uncompromising place.  Well above the 'death zone', the air is so thin the human body cannot sustain itself for long.  Couple that with impossibly cold temperatures, the danger of snow/ice falls, and the sheer immense size of the place, and it makes for a near-impossibly hostile environment.  

Summit Mt Everest is difficult at the best of times.  Realising the immense ambition of PROJECT 321 requires immense physical endurance, and kit that can not only withstand the conditions but also allow Tim to move at a fast enough pace.  

project 321 - layering system


Climbing Mt Everest requires the same approach to kit selection and management as any other day on the hill, requiring a comprehensive layering system.  Heat management is understandably very much the name of the game, but perspiration wicking and breathability are equally important - the point of your layering system being to create an internal environment as conducive to working hard as possible. 

So a number of warm, breathable and wicking layers that can be combined in a number of ways in a versatile layering system will greatly improve performance and safety, allowing for a higher chance of success and survival in this cruel and uncompromising environment.

project 321 - base layers


The Base Layer is vitally important as it is the layer in contact with the skin, forming the basis of many of your clothing's environmental systems.  It therefore greatly influencing comfort, temperature, moisture levels, and in the context of summiting the world's highest mountains; safety.

For this expedition, which requires high levels of sustained activity in a very cold climate, Tim has chosen a 220 Primino Long-Sleeve Zip-Neck base layer; its 1/4 chest zip adding versatility to our warmest weight Primino base layer.

allez micro | montane



In conjunction with his Primino, an Allez Micro provides a versatile accoutrement. it can act as either a secondary base layer or a lightweight midlayer when conditions and activity allow and its POLARTEC® Power Grid™ fabric wicks quickly.


project 321 - mid layers


Mid layers should be durable and comfortable.  Their principal role is to support the base and outer layers; helping transport moisture away from the body, whilst allowing heat to be trapped by an outer layer.  Similarly, they should be expected to keep the external environment away from the base layer if used as an outer in mild conditions.

Tim's choices reflect a focus on versatility and breathability due to the nature of Project 321, with technical fabrics and simple, intuitive features being favoured.

alpha balance jacket | montane



Delivering lightweight core body insulation via its composite construction of fabrics, featuring thermally efficient PONTENTORTO® Technostretch on the main body and weather resistant POLARTEC® Alpha Direct across the chest and upper arms.


hydrogen direct jacket | montane



The Hydrogen Direct reflects 20 years of pioneering fleece pile lined PERTEX® outered garments.  It's cutting edge POLARTEC® Alpha Direct insulation making it a perfect blend of insulation, wind protection, and breathability


project 321 - insulation layers


Due to the drastic variance of temperatures, insulation layers have to fulfill a number of roles; from lightweight high-activity pieces for moving fast during more clement weather, to extremely warm, life-saving layers when the temperature drops to its famously low levels.

An emphasis on packability and warmth-weight ration is important to Tim in this category, as some layers will need to be carried large portions of the day and only used when necessary.  They can also be layered on top of each other to provide extra warmth.

icarus flight jacket | montane



Stretch panels on the flanks and underarms allow for an ultra-breathable synthetic insulation layer whilst allowing for dynamic freedom of movement.  Ideal for on the move and also as an under-shell layer or underneath extra insulation.


deep heat jacket | montane



Designed specifically for high altitude and extreme cold, the Deep Heat has a host of features ideally suited to high-altitude climbing and is constructed with enough internal space to allow for layering over other insulation layers.


project 321 - shell layers


Shell layers are a peculiar idiosyncrasy of high altitude climbing.  It is mostly too cold to rain, so the layers often become more environmental barriers; acting to keep the internal layers protected from biting winds, the leech of melting snow, or abrasive rocks.

They are typically used in conjunction with more dynamic layers such as fleece and/or active insulation layers.

lite-speed jacket | montane



Despite being designed specifically for a very specific use, the Lite-Speed intrinsically versatile.  It's breathable and stretchy Wind Barrier Dynamic fabric allows for a dextrous fit and high output, and the abrasion-resistant print increases durability whilst retaining breathability.


endurance pro jacket | montane



An absolute battleship.  Its GORE-TEX PRO membrane is cut to allow for layering over insulation and sports 70 D fabric on high-wear areas and 40 D everywhere else, providing near impenetrable weather protection.  


project 321 - down suit


In order to combat the cold and exposure experienced above 8000m, mountaineers use Down Suits for summit pushes and extreme weather.  On this expedition, Tim will be using a prototype Down Suit he has helped design using his wealth of experience in such climates.  

It isn't due for release for another year, but stay tuned.
