I am deciding between baseline and zdx carry on.
i bought one of each on Amazon to test before keeping.
I’ve packed both to the max three different times to test different content levels and items and rolled them around the house.
they can fit the same amount of clothes - didn’t use cubes for the test.

the baseline top suit mesh pouch is nice feature
I didn’t fit anything in the top zdx pockets think they’d be for flatter things like wires or small pouches.

baseline felt bigger even though they held the same
I liked the way the walls of the baseline stayed up with the compression system while packing before pressing down
I also like the complete open square for access to clothes when open , vs the slight lip on the bottom of the zdx opening

while I want to keep the baseline bc overall it feels better
but - this is a i big drawback in my opinion -

the baseline compression pops open at full capacity. When I push down it goes flat with a slight gap 1/4” maybe. Then one side will pop up by a click if I push it back down the other end clicks up. If I get them both down as I jolt or rock the bag or turn it the top clip pops open and will continue to pop and open click by click until the top of the bag is not compressed but the bottom is.
this seems like a key issue if I haven’t even taken on a real world trip this is just test packing and general feel of handles test around the room.

Suprisingly the zdx zipper managed to close all the way around the middle with the same amount of clothes
That To me seems more reliable

anyone ever experience that clip popping open with the baseline? How much do you use that feature? How full do you fill your bags?

thanks for any insight
