  • The Trea 35 is a mountaineering backpack with a carrying system developed specially for the female anatomy. It will bring you a new level of comfort on ascents in comparison with a backpack with a conventional carrying system.
  • The use of EVA foam on the shoulders and back give the Trea 35 highly breathable properties for enhanced comfort, avoiding the unpleasant feeling of moisture on your skin at pressure points.
  • With its high-quality materials and top workmanship, the Trea 35 impresses in harsh mountain landscapes with a wide range of practical features: a huge back zipper for easy access to the main compartment, side ski carriers and sturdy ice axe attachments.
