Insulated Fish Bags, anyone with recommedations?

[leonreno]

Anybody here use an insulated fish bag? I am looking for one that would hold say a cobia or king if we mistakenly catch one on or near the flats. I may target some cobia this year but I really don't want to take a large cooler with us, we usually carry two smaller coolers, one for food one for fish (trouts, macks, etc.). I think a fish bag stowed away would be a good alternative than a large cooler that we may never need. Any suggestions on brand, size and dealer would be great.

The ones they have at BPS are pretty good from what I understand.
