MIER'S "Large Lunch Box for Women Expandable Insulated Lunch Bag PU Waterproof Cooler Bag with Shoulder Strap for Adults Work Picnic Beach, Dark Green," isn't just for women, but also for men, especially the dark green one. It's one of the nicest lunch bag and/or mini cooler I've actually seen, as it is very spacious when expanded. It can hold quite a bit of stuff as you can see on my photos above. It keeps your drinks and food cold all day. It's lightweight and very durable. It is also easy to clean. Price-wise, this is definitely worth it. I recommend this lunch bag to others.

I got this for a boating trip with friends as I didn't want to bring our full size cooler and take up unnecessary space. The outter material had a nice soft feel to it and the bottom unzips so you can fit more things inside, if needed. The straps are a pretty gold color and are adjustable. This cooler holds plenty and is perfect for when you need to bring some drinks and snacks with you but don't want a huge ice chest or a tiny lunch bag. I also plan to use it for when we take the kayaks out as it'll fit under the straps I have and I won't have to go back to land for drinks over and over. Very nice!

This review is for the product listed as, MIER Large Lunch Box for Women Expandable Insulated Lunch Bag PU Waterproof Cooler Bag with Shoulder Strap for Adults Work Picnic Beach, Green (Green)."This is a great cooler bag. It is large, well made, and the materials they used are thick and high quality. The outer material is thick, then there is a foam core, and then a lining. All of it is water proof. It holds a lot!

This lunchbox has been serving me well for the past week. The green color and tan strap are a nice contrast. The material both inside and out is very easy to clean with a wet towel. It has been my lunch cold every day this week and is large enough to hold quite a bit of food as well as my 40oz water bottle. Great lunchbox.
