Being of XL size myself, I thought the longer drawstrings would be beneficial. And I was right. The thing about the longer ropes is it gives more room for adjustments. Making it easily more comfortable.
I am 6ft 2 with broad shoulders. The original straps were not long enough once I filled my bag. The Extra Long Drawstrings are PERFECT and were easy to install! I am so glad I purchased these instead of getting rid of the bag!
I had no trouble installing the replacement ropes, as I basically ignored some of the video for the old flacsack because its obsolete and wont work for the flac-sac 2. To have any degree of success,I firstly had to disengage the hooks from the ropes at the end of the chrome grommets so that the ropes could pass freely through the channels when uninstalling/installing them.(dont forget to put them back when you've finished) I then used a half inch safety pin attached to one end of the rope and threaded it through the channels like you would a pajama cord. Using the video to take note of where the ropes go, this was far quicker than using tape for sure.
