What do the pull cords do on the back of the pack? These are green on the black model. And one is near the vertical logo.
Green cords are used to tighten ice ax handles.
I think BD designed the cords and loops to hold ice axes or ice tools. I've used my pack to hold ice tools to climb WI as well as an ice axe for mountaineering, but you can use them for anything that might work for you... I hope that answered your question!

Along with the green straps ( black model ) with buckles at the bottom of the pack the two green pull cords are for attaching ice tools to the pack.
The head of each tool is attached with the straps at the bottom, and the pull cords hold the shaft of the ice tool against the back of the pack.
Quick and easy on and off.
This pack was designed for climbers and the pull cords are not really pull cords but attachments for climbing tools, ice picks etc.., we love the pack and use it solely for hiking and use the cords to tie extra bottles and equipment together. This is an extremely comfortable pack!
And that loop at the top is used for hauling. Do you see that little pull strap pictured in the haul loop? Pull that tab strap to reveal a helmet cover, so you can carry your helmet on top of your pack to save space and to maintain a low profile.
The cords are elastic for securing the handle end of an ice axe. The straps at the bottom have a buckle to secure the pick end of an axe. The pick end slips into a protective pocket. The buckle on the strap can be undone with one hand with your pack on, so you can access your axe quickly when you get to sketchy terrain.
This is a climbing pack specifically for ropes and ice axes. The ice axes attach upside down and hook into the loops ( what u see as tabs) on the sides. The upper hook is a tow loop. When ascending often climbers climb up then two gear up on a rope. Caribeaners attach to the main handle of the pack an to this tow strap ( or upper tab as you see). The pack can be used for more than just climbing but is also a fantastic pack for day use mountaineering.
Thanks so much. That was super fast and I am trying to figure out if I should get the 2014 or 2013 model. This helps a lot. From what I gather the new model is lighter. The old model has better colors. The new model doesn't have dangling pulls that might get in the way, which is why they may have been removed. I am sure that there are other changes too. Tough choice. Thanks for your help.
They hold the shafts of your ice tools. The green straps with clips at the base of the pack hold the heads of the tools, and the picks go inward into each side of that open slot you see.
