The ALP TRAINER 35+3 is our technical mountaineering backpack for two to three-day hikes, featuring our new Dry Back Air transport system designed specifically to keep your back dry. It has 25% less contact with the surface than our previous designs and reduces contact without compromising load control. Its integrated ventilation system with breathable materials allows for a higher airflow on your back. This significantly lowers the temperature between your body and the backpack by 1.6 °C after 15 minutes. Our lightweight split shoulder straps also reduce contact with the body, promoting increased perspiration and comfort, improved airflow, and enhanced mobility. Additionally, the Twin Compression System (TCS) helps keep the backpack close to your back, preventing trips during fast-moving activities, and allows you to quickly and easily adjust the volume when carrying less. We have equipped the ALP TRAINER with all the features you need and none that you don’t. Compatible with the bottle holder Salewa (product code 1303) and smartphone case (product code 1305).
