AO Coolers Traveler Soft Cooler - Insulated for Picnics & Camping

I couldn't tell from the photos, but the zipper top closes like a book bag, not a rectangular cooler. I thought it would be to large for a daily lunch or dinner bag, but it works well. I can't compare it to other soft sided coolers as I haven't bought any others but the construction seems very sturdy. The interior liner is some of the thickest plastic I've ever seen.I like it more as the zipper is straight across the top instead of making it into a "box".After a solid 6 months of using this for my lunch bag cooler, I thought I'd update and clarify my review. The top zipper is doube ended, a feature I like as you can open it from either side, or zip them together in the middle if you prefer.When opened, the cooler opens into a square shape. which makes loading it easier than say a Yet which only opens to a slit. The top is also insulated, where a Yeti is thick plastic. The interior plastic liner is a single piece, so it's not a formed fit, wrinkles and spaces make it a tad harder to clean out but a gargen hose and detergent is sufficien. The one piece construction avoids interior welded plastic seems as in the Yeti.I had doubts of the usefulness of zippered pocket. But they are very handy for storing some utensils or paper plates/napkins, The Yeti doesn't offer side pockets.The insulation is sewn through in some spots (sides, corners) which would effect performance.After 6 months as a truck lunch cooler I'm very satisfied. The Yeti is more extreme, but not needed at teh price point for keeping a tuna sandwich from becoming soggy.This product (AO) looks very similar to the Polar Bear brand but I paid $20 less than that one. I recommend it for the price to performance ratio.
