I carried a ULA pack that had 9 cinch points and it took me two weeks before I could comfortably wear it (I'm used to expedition packs that are heavier, yet more comfortable, strange as that may seem). A Dane and a Brazilian helped get me to a point of comfort. First, I loosened my way too tight "load lifter" straps—the straps that connect the top of the shoulder harness to an anchor point near the top of the back panel—as that was a major source of my shoulder discomfort (thank you, Jens, outside Logroño). Then the waist belt. What helped me most when putting my pack on and ensuring I really got the weight on my hips was to bend over at the waist and get the waist strap above my hips and then cinch it down. The pack was now riding a bit above my hips when I stood up. What a relief. I could now go comfortably for hours (thank you, João, on the Meseta). The ULA Circuit pack is a bit of a strange pack and definitely took more time than I wished to break it in. Or maybe it was breaking me in... All's well that ends well.
