The team tested and demonstrated real world capability of the current ThruDark alpine offering at Cairngorms, in particular Fiacaill Ridge. This location was selected for its variety of technical routes combined with challenging winter conditions. The itinerary included 4 days of climbing and winter mountaineering skills.


All ThruDark garments are subjected to rigorous real world testing by our former UK Special Forces co-founders.


Supporting Expertise

With nearly 30 years of experience between them, ThruDark co-founders Louis and Staz remain highly capable of operating in a variety of challenging environments and conditions. That being said, our expeditions will often make use of highly trained local experts who add immense value as additional hands on deck. Our recent trip to the Cairngorms involved the following to whom we owe a great deal of thanks; Jon Holliday, Scott Mcneish and John Lowther.


We always say 'we don't just stand by our kit, we stand in it' and as brand co-founders Staz and I want to be at the forefront of product development. Getting the chance to put our designs to the test in places like the Cairngorms is one of the most rewarding aspects of the job - it's why we do what we do.
