I used the IA 5k on the Integrous frame in 2024. I packed out 7 animals with it and hunt solo most of the time. It hauled heavy weight really well. The first belt size I ordered was a medium as I followed the recommended chart and it was way too big so I went to a small. That was perfect.i packed out deer, bear, elk, and antelope that season. Mine and my ladies on the elk and lope. I had harness separation on my bull pack out. I had the parts and pieces and a hind quarter and the adhesive on the harness broke free and the 3 point attachment saved that trip. Customer service for me was fine. They sent me a new adhesive patch to replace the faulty one and I was good after that and packed her cow elk out a week later. If they made a harness attachment like kifaru or exo it would solve this issue. I know it doesn’t happen much but there have been other guys on here that have had the same issue. Just something to be aware of. I sold mine after and went back to SG. I just couldn’t get over that happening 3 miles from my truck. Even though it was fixed it’s just not something I wanted to mess with again. If you do get one I would suggest the pannier. It helps keep the load staying put and does a great job
