The opinion of Aventure Nordique

The Sierra Designs Flex Capacitor 25-40 is a backpack with adaptable volume. The horizontal straps on the outside of the backpack allow the volume of the backpack to be compressed. Open to their maximum at the beginning of the hike, you can decrease the volume of the backpack when you have exhausted your food supply. This also allows you to have a single backpack, whether it is for a day hike or a few days, by simply adapting its capacity.


Access to the volume is from the top, using a U-shaped zipped opening. In addition to the main volume, the Flex Capacitor 25-40 has numerous pockets:



  • 2 side pockets made of stretch mesh

  • 2 stretch mesh hydration pockets on shoulder straps

  • 2 zipped pockets on hip belt

  • 1 small pocket hidden in the flap


The frame consists of a lightweight Y-shaped DAC Flex aluminium suspension, ensuring comfortable carrying. The back, straps and hips are padded with EVA foam. Slightly curved, the bag does not press against the back to ensure air circulation.
