This updated version of the popular Ergon backpack, the BA3 E Protect, is now even more user-friendly. Designed specifically for Enduro and All-Mountain use, this backpack is versatile and suitable for a range of activities. The 4-step adjustable carrying system allows for easy adjustment of the back length, providing a comfortable fit for a range of sizes. The "Adaptive Carrier System" load compression principle and flexible aluminium profile ensure a precise fit to the rider's anatomy. The hip strap can also be shortened as needed. The BA3 E Protect features a main compartment with 4 inner pockets, a separate bladder, a front pocket with a small compartment for tools and pumps, and a waist bag. Additionally, this backpack has a back compartment that can accommodate a back protector (BP100) and a bladder (BH300). Even when carrying the battery in the BA3 E, there is still ample space in the protector compartment for the BP100 and the BH150 bladder. With its improved features and functionality, the Ergon BA3 E Protect backpack is a top choice for anyone looking for a high-quality, adjustable backpack for their outdoor adventures.
