Thirty-One now has an insert for that bag to keep it standing tall! I love this insert! Now my bag no longer sags down when not being toted. It attaches to the bag through the grommet holes and comes in four colors. There are a total of FIVE mesh pockets on the inside.
Now, I'm going to be honest and tell you, with this insert, your LUT will probably not hold as much as it did before because the sides are now structured. Without the insert, you could make your LUT bulge to the max when fully loaded because the walls could expand beyond the framed top. However, with this insert, it allows you to organize some items and the bag no longer wilts when put down.
I'm currently taking bookings for December so book me quick before my calendar fills up!
