Product details
The Trion 15 from Mammut is a mountain sports backpack that was designed together with professional alpinists Stephan Siegrist and Nico Hojac. It shines with its lightness, perfect fit and well thought-out details. Perfect for all mountain sports enthusiasts. The recycled material of the Trion 15 is not only extremely light, but also extremely robust. Thanks to the durable water-repellent finish (DWR, without PFC), it is also water-repellent - perfect for a day in the mountains where the weather can change quickly. The carrying system was designed similarly to a trail running waistcoat so that the mountain sports backpack sits close to the body and you have full freedom of movement. The elasticated chest strap ensures a perfect fit and excellent wearing comfort. Quick access to your equipment in the main compartment is made possible by the roll-top closure with zip and the side zip access. Of course, Mammut has also thought about your climbing and hiking equipment. The Trion 15 is equipped with two ice axe holders, trekking pole holders, a rope attachment on the lid and side compression straps - perfect for a day on the rocks. Two mesh pockets on the shoulder straps offer you even more storage options and with the two soft flask holders you don't have to worry about your hydration either. You can safely stow your valuables in the zipped inner pocket, while a key clip in the inner pocket provides the perfect place for your keys. The Trion 15 is like a faithful friend in the mountains - it carries your loads without grumbling. Together you will climb every summit.
