The Trilogy 25 backpack is lightweight and features a narrow silhouette to accommodate free movement and carry well over steep and technical terrain. The new generation back system features a body-mapped, smooth padding that provides comfort against the back as well as structure, for stability and load distribution, while the 3D mesh construction increases breathability and is supported by a lightweight, internal fiberglass frame. The suspension system, responsible for bearing the weight and connecting it to the body, features ergonomic foam-padded shoulder straps and hip straps ensuring comfort and mobility. Plus, the minimalistic top opening is lidless and has a roll-top closure, much like a dry bag, that folds down and seals quickly using compression straps that also acts as a convenient lash point for a climbing rope.
