Great bags
This bag is perfect for an overnight trip. It has 3 outside pockets one with a zipper. It easily fits 2 days of clothes, and a toiletry bag. (Size Large 32L)
I also bought a 3xl - 72L. This one is big enough for 2 king pillows and one smaller pillow. The great thing about it is you can stuff kast min things in there and use the drawstring to enclose everything in.
Very happy with them.

Color: 32l-navy, Size: Large
This bag is heavy duty and a GREAT one. It holds a lot. LOVE that you can extend it and close it up.
Very durable. I'm glad I bought two.

BAGSMART foldable expandable tote (large, coffee)
I got this expandable tote (B0FKGVT9WV) as a replacement for a similar one that I used for quick shopping runs. It's not perfect but on the whole it's an upgrade from what I had. Considering what I paid for it, it is good value for money despite the limitations.
The bag is lightweight but the stitching is solid and it feels fairly durable. The handles are comfortable on my shoulder or in my hand on my walk back from the store (usually ~15 minutes). However, having two sets feels unnecessary. I really wish they'd gone with just the one longer set.
I like the mix of open pockets with one zippered pocket. And the zipper works smoothly; it feels like it'll stand up to repeated use.
The drawstring for the expanding portion of the bag works well. I find this to be a much better design than a standard zipper or snaps for my grocery shopping. This lets me close the bag securely and protect the contents from wind and light rain, and it's much more forgiving when I've got larger items.
The color is exactly as shown in the product description. In person, it's actually very nice and much classier than my former bag.
One thing to remember, though, is that this bag doesn't have any thermal properties, though it is water resistant. For the short distances that I'm going, this is good enough.
Folding the bag is a bit of a hassle, although the snap that secures it is very strong.
The bag is supposed to have anti-wrinkle properties, but I find that it tends to wrinkle fairly easily and that it takes a while for them to fall out. I work around this by keeping it laid flat in a cabinet rather than folded. It's not a major issue for me, but it is a little disappointing.

This bag is huge. No joke.
This bag is giant. Exactly what I was hoping for. Roomy enough to lay folded towels flat at the bottom, all your swim suits and gear. Roomy pockets all around for lotions and sprays. A large zippered pocket for valuables that’s hidden in the seam. Overall the quality is fantastic for the price.

LOVE THIS BAG!
Color: 32l-black, Size: Large
This is an amazing bag for traveling. It folds up easily and took up very little space in my luggage. It made a great multi-purpose tote for our trip. I used it as a beach bag, a grocery bag, and a laundry tote. And when I bought too many souvenirs, I used it as a carry-on to get my goodies home safely. I liked it so much I bought two other sizes.
