I've been ignoring this issue since July when I got the S25 but when I'm wearing the pack and I need to tighten or loosen the straps it just won't budge or slide easily. Even if I hold the buckles strategically like with all of my packs [with one hand] it really won't budge. It's such a hassle for me to remove the pack and then adjust over and over again depending on the load. I think I threw the pack once out of frustration with all the gears inside haha (ooopsie).
Is this a normal issue or is it just me? Maybe my straps are just pigheaded.
