I bought a bunch of Luxe Hiking Gear's UL pullouts. Super cheap compared to the other options out there. They're lightweight and have good construction. This year I switched packs and I'm using the Exo swing out stash pockets. They're a little smaller and heavier but I like how they attach to the side of the bag. I'll probably mix and match some when it comes time to pack up.
I run the Kuiu pullouts and put different color zipper pulls on them. Red=medical, blue= water, yellow= possibles bag. The red tag is extra long for quicker identification.
