The ALP TRAINER 35+3 is our technical, alpine hiking backpack for two- or three-day tours. It is equipped with our new Dry Back Air carrying system, which has been specially developed to keep your back dry. The contact surface of the backpack on the back is thus 25% smaller than with previous carrying systems and reduces body contact without compromising load control. Its in-built ventilation system with breathable materials improves air circulation on the back. This noticeably reduces the temperature between your body and the rucksack by 1.6°C Grand Celsius 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. In addition, the Twin Compression System (TCS) allows the pack to be compressed with a flick of the wrist to keep the load close to the body and prevent tripping during fast-paced activities. The volume of the rucksack can also be adjusted quickly and easily when the load is lighter. We have equipped the ALP TRAINER with all the features that are really necessary and left out the superfluous: It has easily accessible mesh side pockets, a rain cover, a separate bottom compartment and attachment options for poles.
