great bag concept
PROS- love the bag in that it holds everything I need for the day food wise as well as all my gym items. Its very comfortable to wear when full, has plenty of room and storage pockets. CONS- the fabric between the pockets and the stitching used does not hold up. I have had this bag just under 2 months and the fabric between the pockets are already coming apart, so having to stich it up already :(

Great Meal Prep bag
This bag is great if you need to transport a few days of food or a picnic. I plan to bring my meals to work on Monday’s for the week using this bag. I love the protein shaker bottle that has extra storage for powder, vitamins/supplements. This is truly an all in one bag it not only comes with 6 containers but it has room for 3 of them in a zipper compartment on the top maybe for snacks or other non-refrigerated items. It even has a laptop sleeve/compartment. This bag will eliminate having to use a lunch pail, purse, laptop bag and more. Add in a power bank and you’ve got a convenient way to charge your phone or other devices. Great for weekend trips of you want to bring your own meals as well, it fits so much food and is worth the price!

If I could give this bag six stars, I would!!
I absolutely love this lunch box/back pack! I am a working new mom and have the need to transport a lot of items to and from work on the day to day including a lap top, breast pump/supplies, my meals/snacks and various other items. This back pack holds it all and has room to spare! Plus it keeps my meals and breast milk cold all day with only the ice packs that are included. I would highly recommend this backpack to anyone who is looking to contain all of your day to day items and meals in one bag. It is super well insulated and keeps my meals cold for 8 hours plus. As well, the bag is very well made and seems extremely durable. That being said, fair warning, this is NOT a small bag, so if you are looking for something inconspicuous, this is not your bag. But it works great for me!! I highly recommend!!

Wonderful Product
I’m an avid bodybuilder. I have used several large lunch boxes. This is by far the best product ever. Not only does it hold my daily meals, it holds my shaker bottles, supplements, pre workout, intra workout, protein powder, slides, and workout clothes. I have went from carrying 3 items everyday to carrying 1. I highly recommend this bag/lunchbox!

Comfortable meal prep bag
I wanted a large backpack that i could use to carry my essentials as i bicycle to and from work, gym, etc. I enjoy the number of compartments the most. However the main draw back is perhaps the shape of the straps. While sturdy, they feel a bit tight around my shoulders as a broad person. If this is aimed at bodybuilders, they should consider that most of em need the extra room to avoid chaffing and discomfort. I also got this a month ago and some of the fabric around the zippers have started to fray, which sucks. The rest is sturdy tho.

As an office worker who weight trains and packs my lunch daily, I was looking for a way to pack my daily food needs and have my computer, charger, tablet, etc., all in a single bag. The 519 Fitness bag has met all my requirements. I can pack my four meals in a compartment that is easy to clean, I have my vitamins in a pocket on top, my laptop and tablet go in the back, I have pockets on the side for water, extra pockets for cords and chargers and still have extra room.

The bag is great for doing what it needed for me. Has a laptop slot and room for important papers I need to carry around. Plenty of space for extra snack things or chargers up top compartment. The cooler part is just ok. It’s not very sturdy and the top part will collapse down onto the cooler. The separation compartment could be a bit stronger to hold up top half of bag. The negative about the bag is that the sticking doesn’t hold up after a few months use. It’s already past the return deadline and can’t return it now. Good bad, but beware that it won’t hold up overtime. I thought spending money would get me quality. It wasn’t as good as I thought it would be.

Purchase this item a few months ago. Started using it for a month now and all the inseams of the pockets have frayed and ripped. This item was only used in normal conditions for my lunch. I reached out to the company for customer support and they have not responded - this was two months ago and still waiting for a reply.
