sl women’s fit

this model is also available in the sl version, tailored specifically for women: typically, women have shorter backs than men. therefore, the carrying system in the sl model is slightly shorter than in the deuter standard backpacks. plus, the system is specially adapted to the female body shape. more details about our.

our unique airstripes system ensures effective ventilation. it consists of two contoured, air-channelled foam profiles covered with a highly breathable wide air mesh lining. this reduced contact surface enhances fresh air circulation. additionally, the pack’s load stays close to your body for better balance.

the result:

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

pfas free

this deuter product is free from intentionally used pfas (per- & polyfluorinated chemicals), minimizing the use of substances known to harm both health and the environment.

for outdoor products, pfas are mainly used for water-repellent treatments.

instead, deuter has been using alternative durable water repellency (dwr) impregnation since 2019.

100% recycled pet material

the materials used in this model are sourced from post-consumer pet bottles.
