No subject to promotional offersThe Trilogy 25+ White from Millet is an alpine and ski touring backpack designed for adventurers who move fast on trails and peaks!
This model, available in two sizes, is made from super abrasion-resistant Dyneema® for exceptional durability. Furthermore, to quickly adjust the ventilated carrying harness, simply use the BOA® adjustment system at the back. And that's not all! The 3D mesh shoulder straps are very comfortable, and the two adjustable and removable chest straps allow you to ideally distribute the load weight across your shoulders. Finally, the durable water-repellent treatment DWR ensures excellent water resistance, keeping your gear dry throughout your outing.
As its name suggests, this backpack has a 25L volume so you can carry all your essentials. Storage includes a main compartment accessible from the side and compatible with your preferred hydration system, a front mesh pocket, and an inner zipped pocket. Additionally, there are various gear holders to carry flasks, a pair of skis, and even ice axes. The compression cord ensures precise adjustment of all compartments based on the load carried.
Bonus: if your backpack fabric gets damaged, you can have it repaired by the Millet workshop.
As you can see, the Trilogy 25+ is the ultimate alpine backpack, the very best for reaching summits on skis or on foot.
