This is a great cooler/lunchbox. I also have the 20 quart. I tested it on a 16 hour work shift and the ice had barely started to melt by the end of the day. Food stayed cold far longer than it would in previous lunchboxes I have owned. It seems just as heavy duty as the larger cooler. This cooler will fit in the 130 L hard case with a lot of space for other gear.
This makes a great lunch box while on the road. Keeps my iced tea and sandwiches cold through out the day.
Purchased for the spousal unit and he just loves this cooler!!! Keeps everything so nice and cool. Fits in the car w/o taking up too much space. Perfect for road trips and and also for trips to the grocery store when running multiple errands on a hot day. Happy Hubby, Happy Wife ;-)
