I have a RUSH 24, and while I'm still tweaking things here and there, it is a great work bag. Stuffing jackets and other bulky items within it still poses "issues" depending on the make, model, size etc. and the load out you're carrying, . A 2XL jacket will take up more space than a Medium for instance. During the winter months I've stuffed my jacket plus two water bottles in the main compartment with no issues of overloading. It makes for a "full" pack, but not a lot of weight, and the compression straps can keep things tight I don't care for "shove it" pockets, bungee cords etc on the outside of the pack as the jacket can get snagged and then possibly ripped. If you want to stay within the 5.11 series the COVRT 18 fits right between the RUSH12 and 24 as far as the "numbers" go and has outside water bottle holders which free up room in the main compartments. A possible solution for getting the jacket to "fit" better might be a compression sack for the jacket to give it the smallest signature possible within the bag. Quilted jackets don't always fold up very small, but a compression sack might give you just that little bit of extra room that makes it fit. I like my RUSH 24 and use it like a "locker" to hold all my items at work. During the summer I could use a RUSH 12, but once the Canadian winter hits the RUSH 24 holds my uniform jacket, wool hat, gloves and the rest of my gear. While there are other great packs out there, my RUSH 24 has served me well in the last seven months and gets my vote for being a good all around pack to suit my needs.
