Surf to Summit Insulated Fish Bag

This is being sold at REI in their sale-section.

It occurs to me that if this will keep a fish you caught cold and safe to eat until you got to shore and cooked it, it would aslo keep your lunch cold until you could eat it!

Does anyone have experiences or thoughts about this?

Isn’t it Sea To Summit’s bag?
Saw a gigantic insulated fish bag at Aqua Adventures. Big enough to hold a lot of food!

Could do double-duty as a frozen-foods hauler for grocery shopping.

I have the Sea-to-Summit deck bags.

This one is differnt.

The site lists it as the SURF-to-summit Insulated Fish Bag. #815508
