HILUSEN Extra Large Backpack for Men 50L, Insulated Cooler Lunch Box Backpack, Water Resistant 17inch Travel Laptop Work Bookbag with USB Charging Port,Black

I use it for assembly line work. It holds my Milwaukee drill and holster for the big area, all my PPE, my phone and portable phone charger, various other little things, and the lunch holder is waterproof and holds cold temperature all day with a few freeze packs. And if your backpack isn't cram packed you can fill your lunch holder with a lot because it's flexible and can go all the way to the back of the backpack. The durability is good so far, but I've had it for only a few months but it's still fine. I love the look! Black and grey with traces of red just looks good.

Very nice back pack lots of space and good price. If anything I would update the charging port as most electronics today are C port.

Just got this backpack so the jury is still out but I will give the benefit of the doubt! I wanted to share a picture of the pink flowers and black background because I noticed the reviews had a lack of them (or none). LOTS OF SPACE. I love the strap that holds my iron flask in place. I bought this mainly to fit a carrying case for a console I have and it fits wonderfully. Jury is still out because I have yet to really use it and have only put my belongings in it once it was delivered.

Very sturdy, had alot of pockets! Very pleased with the purchase!

I was very impressed with how much room there was in this backpack. The lunch compartment was a lot bigger than expected. The pockets and space to store you belongings is great. My favorite is the strap to hold the tumbler in place. The only part was the brand name in big letters but that’s about it.

Very sturdy, it has alot of space and deep pockets. And the shoulder straps are sturdy and comfortable too. I love this backpack. I use it everyday for work.

I use this all the time. It has all the things I need for work in it. It keeps everything cold and has so much space. It is very durable and lightweight. The price is also good for the quality of product you get.

This backpack has it all. It has four compartments one of them for food so you can take your lunch to work or school. The smaller compartment for your writing utensils and small tools. Extremely durable. Very comfortable and The compartments are very large so you can store lots of things in them. It's more like a suitcase than a backpack but I love it. I'm definitely going to buy another one for my brother
