I have a Kuiu Ultra6000 and it squeaks. I have taped it and made sleeves for the frame and it still squeaked. I never could get it to carry loads real comfortable. Then one day I broke the buckle on the hip belt when tightening it up. Tried contacting Kuiu to buy or get another buckle, and never heard from them. Still get their catalogs though. I stopped in at EXO and tried on their pack one day. No comparison. I'll probably never wear the Kuiu again. It sits on the shelf unless I have someone who needs to borrow it.
