Keg bag for ferm temp control

[TedsExcellentAdventure]

Has anyone tried these instead of a larger bucket to insulate and cool a fermenting bucket, it's basically a giant bag for keeping a keg cool, I'm assuming it would work similarly to cooling a keg

You could try it. I'm doubtful about how precise it would be.

The ones I've seen are $50 + shipping. I'd suggest putting that money into a used freezer or fridge, slap an STC-1000 on it and have really good temp control for not much more $$.

Ya I'm not thinking it's going to be too precise, what are they made out of that they're that expensive? Haha we have some at my liquor store for $3.99.
