Am I normal? When I carry 50# in my packs the number one problem I have is that I can feel the weight of the bag sitting on my glutes, instead of transferring to to the hip belt. I do have large muscular glutes and a slightly more than normal lumbar curve. My packs are brand name expensive packs - New Zealand made Macpac, Lowe Alpine Sting (least affected by this issue - seemed to fit my lumbar curve the best) and currently a Karrimor SF. I'm wondering if I should spring for a Kifaru which admittedly costs about double of my current packs, but when you are carrying 50#+ to NOT carry it on my buttocks is worth it. I don't have any friends to check out their packs so... am I normal or is this just part of the experience?
