Yeti is a good brand but they did fight for gun control if you care about that. My dad has two full size yeti coolers and they will keep ice for a ridiculous amount of time. That being said, I have only experienced their coolers, not their bags.
Pros:
>bombproof construction
>awesome at keeping ice cold
>brand name shit, people will admire it if you care
Cons:
>>>>>>>price
>i absolutely hate the fasteners they use on their coolers. seen them break several times
If you're looking for a cooler, I recommend pelican. Way cheaper and just as functional, keep ice for the same amount of time. The fasteners are way more bomber and I've never seen them fail.
