Welcome to the obsessive world of ultralight backpacking, where every gram is scrutinised and your toothbrush handle gets sawn off in the name of weight savings. These packs represent a complete philosophy shift – strip away everything non-essential to achieve that magical feeling of barely noticing what’s on your back, even after 20 miles across the Pennines. We’ve tested featherweight marvels that weigh less than a pint of beer yet comfortably carry multi-day kit up Scottish munros, and cottage industry creations that redefine what’s possible when you prioritise function over features. Going ultralight isn’t about suffering – it’s about moving efficiently, arriving less tired, and discovering that you actually need far less than you think. These packs are for hikers ready to embrace the “less is more” philosophy and experience the freedom that comes with truly lightweight kit.
