ROCKBROS Backpack Cooler Bag Insulated Leak-Proof Soft Cooler Waterproof 30 Can Portable Large Backpack with Cooler for Camping, Beach, Picnic, Party, Fishing, Floating, Outdoor Activities

I wanted a laser welded backpack style cooler because I didn't want a soft cooler with stitching in the inside liner, as they tend to leak or absorb water. It's tall enough that the 32/40oz insulated bottles fit with room to spare above or below it. Check with your airline, but the dimensions are just about a carry on size. I might use it later to bring hot or cold food items home on interisland trips (Hawaii use case).Build Quality: Good for this price point. The cooler portion is laser welded and the rolled nylon straps seem well made. The zipper is stiff (as most of these style coolers are) and it comes with a tube zipper grease. Follow the instructions and apply some from the beginning and it will really make things easier. My cooler doesn't leak, doesn't sweat and if you leave it in full sunlight, really feels like it's protecting the contents with good insulation, even on the lid. I will be adding accessory packs to the sides to carry some utensils, napkins, maybe hand sanitizer.Performance: I mostly plan to use this for picnics and less-than-one day trips. For example, carrying my surfboard to the beach tucked under my arm and carrying the cooler on my back is way easier than carrying a hard handheld cooler.Comfort: If you plan on hiking into remote spots for 1+ hour hikes... Try on some brands at your local store and if they feel good, buy them. I like the chest strap, which helps keep it centered and the shoulder straps don't seem to loosen as I walk. I feel like it doesn't really get super comfortable, but I'll try to explain. If I hike it up really tight, that seems to work best, if you keep it loose like a sagging backpack, it bounces on your lower back and that's not ideal. Maybe a person of taller or larger build might find it ergonomic, but at 5' 7", I think its back height might be a tad too tall for me. Quality hiking backpacks come with adjustable back heights or you buy the size made for you, and having tried those on... My guess is this is a tad too tall for it to "fit" me as the top keeps pulling away from my back, but maybe that's added airflow and a plus? However, I only plan to use it for convenience from parking lot to picnic or beach spot, and not major Backcountry excursions, so I am willing to overlook minor comfort/ergonomic issues because it's way more comfortable than carrying a similar sized hard cooler with my hands while trying to carry your recreational gear as well. It's also better than trying to sling a single shoulder strap rectangle/square soft cooler and carry say, a surfboard. In that perspective, it's comfortable enough to not knock the stars down since they don't advertise back height or that it's custom designed for someone my height. It's design is better than hand carrying a cooler based on how I am using it, so for me it's still a winner.Compared to a similar size Hydroflask 20L backpack cooler I tried on, this one keeps it's shape better. Perhaps that's where the Hydroflask model might be more comfortable, but in the store I didn't have the Hydroflask loaded with cans, bottles, ice or food. I wanted something to keep it's shape so that food won't get smashed if the sides deformed naturally, and so this fit my needs well. This item keeps it's shape top to bottom, at the expense of a little bit of comfort. I also thought the sliding opening for the Hydro was slick, but wouldn't be as good of an insulator as this thick top lid and it seems like you had to use one hand to keep the Hydro open as it naturally closes, whereas you probably use both hands to unzip this, and when you flip the top back it's wide open.

I was on vacation and needed something to carry moderate amounts of frozen food on flights where it would be 16+ hrs from packing to destination. I’d used standard cooler chests before with mixed results, so I thought I’d give this a try.I used the standard ratio of 2:1 (freeze packs : frozen food). I also froze the cooler for 3 days before packing it. I then placed the cooler inside a rolling suitcase for protection, ease of transport (more on that later), and as another small layer of insulation. All the food arrived frozen, even in the middle of summer. I doubt, though, that it would have been possible without having first frozen the cooler for 3 days. (It will consume the majority of space in a typical top mount freezer.I did not carry it using the back straps because 1) it would have been quite cold on my back and 2) the heat transfer would have warmed the cooler and then it’s contents and 3) even if I was not concerned about temperature, it would not have been comfortable. The straps appear sturdy, but they are not designed as well as a decent travel pack of similar size. Neither a sternum strap nor hip belt is present. Both would be welcome as it is quite heavy when loaded.This would be fine for a car picnic where it might be a short hike from the car to the site. I’d think twice about using it as an overnight cooler for perishables, unless you use plenty of cool packs and freeze the bag first: it takes a lot of energy to get the bag cold.I’m happy, but I believe that a styrofoam box would do almost as well, except that, even when protected in a suitcase, styrofoam is prone to break in the rigors of an airplane’s cargo hold and, especially, the baggage handling system.Is it worth the asking price? Depends on use case. It worked fine for me, but it was not without effort. On the other hand, if you already have a pack that will hold a styrofoam cooler of similar shape, you can get 80% of the convenience and much of the insulating power for less than 1/10 the cost. It may not be as “elegant”, but it will be more comfortable to carry.
