insulated lunch bag

Does anyone have an insulated lunch bag they recommended?
I’ve been bringing prepared shakes/fruit etc to work and the fridge here is gross so I don't want to use it LOL. I want something I can fit my shake cups into and leave on my desk that will stay cold until lunch, also something not too bulky since I take the train to work.
Any suggestions?

I dont have rec for a bag but i always bring lunch and leave my lunch cooler on my desk but always use ice packs

Anything big enough to fit the largest tupperware container you would use.
I personally like something with a wider bottom - to fit a sandwich tupperware or my largest salad one - with room to anything else I want to take with me.
Handles that I can loop over my arm instead of carrying in my hand are a big plus.

I bought one at Home Goods that I liked and was inexpensive, can't remember the brand.

I've gotten mine at HomeGoods/TJ Maxx...they always have a ton! Don't know what the brands are, but I would use ice packs if you are leaving it on your desk and it should be fine.
