Here is the Alp Trainer 20, our technical hiking backpack for relatively short alpine routes. It features our new Dry Back Air transport system, specifically designed to keep your back dry. With a 26% reduced contact surface compared to our previous models, it limits body contact without hindering load control. The ventilation system integrated into the breathable materials allows air to circulate on your back. After 15 minutes of activity, the new Dry Back Air system reduces the temperature on the back by 1.5 °C compared to our previous Air Fit system. Our lightweight split shoulder straps also reduce body contact, further promoting sweat evaporation and comfort, improving airflow and increasing mobility. Additionally, the tandem compression system allows you to secure the backpack to keep the load close to your back for stable movement. It also lets you adjust the volume quickly and easily when you've taken off your rain jacket, etc. We have included all the features you need in the Alp Trainer backpack, and none that you don’t. They include: an easy-access front pocket and mesh pockets on the sides, a rain cover, and an attachment for trekking poles. This backpack is also compatible with the Salewa hydration system and equipped with a hydration system.
