60 days to change your mind No subject to promotional offersThe Trion 28 White/Black is a backpack from the brand Mammut designed for mountaineers and enthusiasts of ski touring and climbing.
This lightweight and robust pack is made from abrasion-resistant materials. Its very practical carrying system, consisting of elastic straps and a padded waist belt, ensures you enjoy optimal comfort and a perfect fit. This versatile pack is made water-resistant thanks to a durable PFC-free DWR coating, which will particularly appeal to environmentally conscious mountaineers, with its bluesign® certification and material partially made from recycled fibres.
On the practical side, the Trion 28, created in collaboration with professional mountaineers Stephan Siegrist and Nico Hojac, features several easily accessible compartments. These include a main compartment accessible via a roll-top zipped opening or a side opening, mesh pockets on the shoulder straps, a compartment for storing avalanche equipment, and a water-repellent zipped outer pocket. Additionally, two sturdy ice axe holders, a pole holder, a reinforced ski carry system, and another attachment point for securing a rope on the flap complete this ideal setup. Finally, this backpack is compatible with the use of your preferred hydration system.
