The JETFORCE BT 35 is the Pieps airbag backpack. Thanks to the latest development, the BT series features wireless device management with Bluetooth and Pieps-App. In addition, the Jetforce BT has a flexible, modular Zip-On system - so you can choose the Zip-On according to your needs.
Here you have the 35L zip-on. It is ideal for long tours with lots of equipment and multi-day tours. Sufficient space, many small pockets, numerous attachment options including ice axe holder leave nothing to be desired.
