The pouch is a little larger than I expected it to be, although I do find the size is perfect for its stated use case and think it would likely be perfectly at home on most packs or bags (mine lives on my Mystery Ranch sling bag and feels right at home). Able to fit my iPhone 13 mini in its case (with some room to spare in both width and depth/thickness), a slim 4000 mAh battery, and a short charging cable, it still has additional space in the front-most pouch for small items. The build quality is excellent (as it should be for the price), and the materials are top notch and thoughtful in their selection (the Fidlock closure and the X-Pac pouch material in particular). Making the small and thin pouch frame sheet removable is also a smart choice, allowing for possible replacement by the end-user in the case of damage/wear or simply allowing for a less rigid overall pouch shape if desired. The only real gripe I have with the pouch is the lack of inclusion of any means for pouch attachment with the pouch itself (PDW's HAL1 straps are sold separately for an additional $3 as stated in the product photos). Ideally bundling attachment hard/software with the pouch (as some comparably priced competitors do) or even discounting the "optional"/separate attachment straps when they are purchased in conjunction with the pouch would be great to see given the price of the pouch and is my only criticism (and the sole reason for lack of a "perfect review" score - I wish half star ratings were possible). That said, the pouch itself is fantastic; PDW and Carryology knocked this one out of the park!
