Size: 24 can Color: Black
My boyfriend has been very satisfied with this lunch box so far. Love that it has a hard case inside and plenty of space for tons of snacks, drinks, and his 64oz hydro flask bottle. It offers side pockets for extra storage plus a large magnetic flip top (with large opening) so he doesn’t have to unzip it open every time he has to grab something out of it. We also bought two large Igloo freezer ice blocks (5.6”x8.75”) to sit underneath his stuff and it basically covers the entire bottom of it. It keeps everything inside cold for the whole day, which has been super important for him during the summer months since he works outside! Definitely well made and worth the money👍🏼 ... show more

    • Great cooler for dog sports!!!!

I'm using this for our dog agility trials for Owen's water and treats and my drinks i need to keep cold and it works great! Plenty of room and everything stays very cold! I also really like the pockets on the sides for things that don't need to stay cold.

    • ITS BIGGER THAN IT LOOKS!

Honestly, I was a skeptic at first, but as soon as it arrived, I noticed how big the inside of the bag was and I’m in a job where I work long shifts so the fact that I could fit two of the bento boxes in there with the ability to fit three is amazing to me with a water bottle that’s larger than the average size bottle with room for snacks if I choose to definitely a must buy for people that want big bags with a style look to it. It comes with a lunch bag and a bottle opener on the front of the bag near the logo. In my opinion there’s nothing wrong with getting the smaller one, but there’s no point because you can get bags that are the same size as the smaller bag for a better price but if you’re going for the size and the style that I wanted, this is the perfect bag for You. ... show more

    • Quality and won’t leak
Size: 12 can Color: Black
Great quality and will never leak, also has a none cooled space for snacks. It has a hook on the back to hang from headrest in car or on a fence.

    • Simple lunchbox for the working man. Albiet, overpriced when not on sale.
Size: 24 can Color: Gravel
It's big... It's not a GIANT box, but it's big enough to carry 16oz cans on their sides and one the other direction. It does a "decent" job at keeping things cool inside, but nothing to write home about. That's probably due to the magnetic quick open lid. Though, where I work we have a fridge and this keeps my lunch cold enough for my half hour commute and about 30 minutes sitting around. While these are on the more "expensive" end of basic style lunch/trail boxes, I can say it's pretty decent. There's only two pockets, equal in size, on either side. They hold the essentials and are bigger than most side pockets on hard style boxes like this. Overall, it's a decent box if you get it on sale, but I wouldn't spend the full retail price on it. There's better options in the $80-$100 range. Pros : -Large, can carry a LOT of cans, bigger bottles, and large lunch tupperware. -Easy to carry, the dual handle straps or the over the shoulder strap are easy to use and don't feel like they're made of razor blades -Large side pockets for keeping the essentials you need with you. Cons : -Expensive. For what you get, it's pretty basic and there aren't much for "features". It's a lunch/trail box, what do you expect? -Quick access magnetic lid doesn't quite seal causing this box to not keep things as cold as long as competitor brands. -Quick release clips for the shoulder strap are cumbersome to deal with. I never remove mine, but it can be a pain to do so. Overall, I give this a 4 out of 5. The quality seems good, the capability is alright, and it's a simplistic easy to use design. It's very easy to disassemble and clean. But for the money, there's better options on the market. I got this on a pretty good sale and am happy with the purchase. But if it wasn't the sale price, I'd probably pick something else. The quality is nice, but definitely not worth the $30 more over competitors options. ... show more

    • Great lunch box
Size: 12 can Color: Pitch Grey
Was a birthday gift for my young adult son to use for work and he is very happy with it, he likes the how it looks and it fits a good amount of food and drinks in it without it being too big to bring to work as a work lunch box

    • Keeps everything cold.
Size: 12 can Color: Royal
This cooler is made well and holds more than you think. You can use it for work, picnics or other activities. It keeps whatever is inside nice and cold for hours. This zipper is sturdy and easy to use. This cooler is not too heavy and the price is great. You will get lots of compliments on how stylish this under armor cooler is. ... show more
