On the practical side, the Trion 15, created in collaboration with professional Stephan Siegrist mountaineers and Nico Hojac, has several easily accessible storage compartments . These include a main compartment accessible via roll-top a zip or side opening, mesh pockets on the shoulder braces and a water-repellent outer zip pocket . And that's not all! Two sturdy ice axe holders, a pole holder and another frame for attaching a rope to the flap complete this idyllic picture.
