Today I made an ultra light option fir my 2022 built pop up 30. This would work for the 40 as well...
I purchased the back strap ( designed for the 2020 style pop up) and sewed on 3/4" webbing to the 1" existing webbing to attach to the 2022 frame. Then I sewed on two loops on the top as far apart as possible, and made two straps with loops on each end just long enough to go through the molle webbing on the back strap.these two loops are what the side tension straps clip too. I took an ultralight backpack ( 10l type that fold up into its own tiny pocket) and sewed 2 loops with G hooks attached to hang off the two loops sewn on the top of the back strap. The ultralight pack gets hung and sandwiched between frame and backstrap to carry personal items.. then in meat haul configuration you just hook it on the outside of the back strap using the same Ghooks and loops and can sich it all in with the side compressionstraps or just leave it loose hanging on those loops. Extremely simple mod to the backstrap for a crazy light/ small pack with all the meat hauling ability..
