Expedition Alpine climbing pack dedicated to committed alpinists looking for extreme weight-savings, performance and versatility to achieve ambitious projects in the most demanding environments on the planet. In addition to being very light and supporting heavy loads while being comfortable to carry, it can also be stripped down to be used during the ascent. A steal for all those looking for ultimate versatility and minimalism. The pack can be adjusted to the load and volumes requirements during an expedition.The optimized fit and carry structure handles heavy loads extremely well, while remaining comfortable when climbing. It can be stripped down by approx 200g. The materials used ensure an incredible weight/strength ratio and are ultra-resistant to UV, which are very present at high altitude. The Stache was used and tested in high altitude environments by several of our athletes and professional mountain partners. Their feedback was applied to find the perfect balance between being light weight and versatile.
