The ALP TRAINER 30+3 is our technical alpine hiking backpack designed for two- or three-day tours. It features our new Dry Back Air carrying system, specifically developed for a dry back. The contact area of the backpack on the back is therefore 25% smaller than previous carrying systems, reducing body contact without compromising load control. Its built-in ventilation system with breathable materials enhances air circulation on the back, noticeably reducing the temperature between the body and the backpack by 1.6 degrees Celsius after just 15 minutes. Our lightweight, split shoulder straps also minimize body contact for faster moisture transport, increased 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 adjustment of the backpack's volume when carrying less. We have equipped the ALP TRAINER with all the essential features while omitting unnecessary extras: it includes easily accessible mesh side pockets, a rain cover, a separate bottom compartment, and attachment options for trekking poles.
