Quick and easy mod to fit a Gen 1 Kuiu 1800 on a Stone glacier frame. All you need is 5x buckle delete kits from Marsupial gear. I’m a fan of these quick connect clips. They are lightweight, strong, and durable. This should make good use out of a bag I had sitting around the house.
The 1850 fits great, its been my go-to daypack for the last couple years. Unfortunately I think its been discontinued.. I don't think the newer bags will work because of the way they connect to the frame. The 1850 (and the above 1800) have webbing loops on the top that you can connect the straps to with buckles, but all the newer bags have a "sleeve" that slide over the frame.
