Yoillione Felt Backpack Organizer Insert for Women and Men, Large Travel Rucksack Insert with High Capacity, Lightweight Bag Organizer with Zipper Pockets

I liked the size. It fit my loungefly canvas backpack. The organization is great.

It gives the backpack more structure, too - I didn't love how slouchy it looked before. The insert obviously takes up a bit of room, but now I can actually find things. Based on the dimensions, I thought it might be a little too tall, but it fits my Kanken Mini backpack perfectly. I'm very pleased with my purchase. Highly recommend!

Just fits a 4th gen iPad Air in a case in the tablet pocket. It will not go in with the Apple pencil docked.Organizer on the whole just fits in a kanken mini. Feels correct, gives the bag a lot more structure.Only real gripe is the felt design of the pockets means most of them are fairly narrow and/or have limited forward flex. I wish the sides were elastic or it had fewer, wider pockets or something. I've still made it work, but (for example) my inhaler will go in a skinny pocket, but only upside down. Think more pens and small supplies for all but the 1, and even it is limited by the stiffness/slant design pulling away from the organizer. Not a deal breaker for me, might be for you. I'm predominantly using it for the tablet pocket and the large central one. Fit but was a bit overwhelmed with the iPad and an OLED switch in a fairly regular case. In a specifically slimmer case it fits much better and still allows some things beside/in front of it.Will say I've accidentally knocked my backpack on the laminate floor (couch seat height/coffee table, not from standing) and my iPad is fine. I did leave the Kanken seat pad in for extra padding.

I wasn't sure this would fit, but it actually feels nice and snug in there. The material is nice, ample space, zipper pocket, and multiple pouch pockets. I'm not sure about other backpacks, but this fits great in a Fjallraven mini bag.

Loved the design but so large would fit in the sling backpack. Returned
