Good size but needs some more design.
The pack had good ports for tubing and Velcro in the right places for bags. The pump area however is where there needs to be more thought. The view window is great but when there isn’t anything to hold the pump up against it the window is useless. I ended up getting some foam for the bottom of the bag and custom cut it to keep the pump centered and up against the window. There was also some Velcro over top of the window that had no purpose when using the pack for a Kangaroo Joey pump so we cut it off since it overlapped the window.  The shoulder straps are comfortable for my husband and he likes the color choices as his old bag was only in black. Thank you for maki g this product, there aren’t a lot out there and it is part of his everyday life.
