top features of the trail 25

superior ventilation for a dry back

thanks to a reduced contact surface and large ventilation channels within the deuter airstripes back system, coupled with perforated shoulder straps and hip fins, you’ll enjoy optimal airflow. this system also ensures the weight of the pack is carried close to your body, providing a snug and secure fit across different terrains.

safe on via ferratas

the loops on the shoulder straps allow for easy access to your via ferrata set carabiners. combined with the compact and snug fit of the backpack, this guarantees enhanced safety while tackling fixed-rope routes.

practical features for fast action

with a generous front zipper opening and an elastic front stash pocket, your gear is always at your fingertips while remaining compactly stored.

our innovative airstripes system ensures effective ventilation, featuring two contoured, air-channelled foam profiles covered with a highly breathable wide airmesh lining. the fewer contact points enhance fresh air circulation while keeping the pack’s load close to the body to maintain balance.

the result:

the minimal contact surface area of the profiled airstripes allows for free air circulation over 80% of your back, while still providing a secure and compact fit.

100% recycled pet material

the fabrics used in this model are crafted from post-consumer pet bottles.

climatepartner certified product

by integrating more materials and technologies with a smaller carbon footprint into our collections, we are making strides in reducing our co₂ emissions. despite our best efforts, we can’t achieve climate neutrality for all products. that’s why we’ve partnered with climate partner to offset any unavoidable co₂ emissions. moving forward, the emissions generated from the production and transportation of any climatepartner certified deuter product you buy will be compensated through voluntary offsetting and targeted investments in specific social and climate protection projects.

pfas free

this deuter product contains no intentionally used pfas (per- & polyfluorinated chemicals). deuter aims to reduce harmful substances that impact both the environment and your health.

in outdoor products, pfas are primarily utilized for water repellent treatments.

instead, deuter has employed alternative durable water repellent (dwr) impregnation since 2019.
