The ALP TRAINER 35+3 is our technical alpine hiking backpack for two- or three-day tours. It features our new Dry Back Air carrying system, specifically designed for a dry back. The contact area of the backpack on the back is therefore 25% smaller than with previous carrying systems, reducing body contact without compromising load control. Its built-in ventilation system with breathable materials enhances air circulation on the back. As a result, the temperature between the body and the backpack noticeably decreases by 1.6°C after just 15 minutes. Our lightweight, split shoulder straps also reduce body contact for faster moisture transport, greater comfort, improved air circulation, and freedom of movement. Additionally, the Twin Compression System (TCS) allows the backpack to be compressed with one hand, keeping the load close to the body and preventing tripping during fast activities. It also enables quick and easy volume adjustment when carrying less load. We have equipped the ALP TRAINER with all the essential features and eliminated the unnecessary: it includes easily accessible mesh side pockets, a rain cover, a separate bottom compartment, and attachment options for trekking poles.
