top notch

I ordered 3 of these and they are great. opened one pack to taste test them and I ate them as meals for a day and shared the rest of the open pack with friends.
they taste like the lemon girl scout cookies and a little bit like sugar cookie dough. I LOVE THEM. I will be ordering many more for emergency and camping supplies

These are the core of my evac jump bag

I wrap each of three 3600 calorie Mainstay packages in two gallon size zipper seal freezer bags (for storage after the package is opened and for spare storage in the field) and 36 Datrex water pouches as survival rations in my jump bag and as a backup for my MREs in my emergency pack. After living in "hurricane alley" in NC and VA most of my life and having directly experienced ten hurricanes and their secondary tornadoes, I know how uncomfortable evacuation without food and water can be and these bars are flavorful enough and of a good enough texture to make emergency meals something to look forward to instead of something to be dreaded and that psychological advantage can mean everything when the chips are down, no matter what your survival training level may be.

Really taste good

These taste good, they aren't gritty and they don't have that "turn to putty" quality as you chew them up. I can easily see myself surviving on these alone for 72 hours. Short of that, they make a great high energy/low weight snack. They make most trail mix look kind of punk...

Ocean Ditch Bag

My husband is a commercial fisherman in New England and I wanted to create a ditch bag for him in case anything ever goes poorly at sea and he has to jump ship. He hates coconut and sweets, so it was a difficult task as most of the emergency food bars fall into that category. These, however, are neither sickly sweet nor coconut flavored. Score! They have a lemon flavor, which is incredibly light, and while they are not crumbly they are slightly dry while still being somehow moist. It's an odd consistency, but it isn't at all off-putting. I imagine it's this weird property that allows them to be non thirst provoking. While these would be great for any emergency bag - and we're getting more for our home and vehicles - I'd highly recommend them for anyone who frequently goes out on the water. The shelf life, coast guard rating, and the fact that they don't make you thirsty after eating them make them perfectly suited for an ocean ditch bag. Also added 6 days worth of mini datrex water pouches, signal mirror, good knife, para cord, sleeping pouch, poncho, signal panel, waterproof tablet/writing instrument, small fishing kit, small first aid kit, flares and some old fluorescence I got from my father.

Amazing value.

The price for a months worth of these is about $70 dollars, whereas a months worth of MREs costs $330. They take up far less space than MREs, taste better than a cold entree right out of the bag, and are quicker to prepare and eat in an emergency. Even if these things tasted like garbage i would still recommend them, simply because for the price you can have four times as big of a survival food supply for the same amount of money. They may not be individually wrapped, but the package is resealable so its no big deal. Ill be buying lots more of these.

very tasty

Very tasty and filling. No bland after taste. The only thing that could make these better is to have them individually wrapped. Great product.

Time Savers

First had these at our local P.X. on our base, These Food Bars & Others Kept me fed during those Long, Lonely Nights on watch, Some of my watches lasted 10 to 12 hrs. & I'd miss my Meal Breaks, They helped to keep me alert & To pass the time. Tasted great too. Also great crumbled up & Placed over Hot Cereal.

I was pleased with the size of the bars and the taste. Have 2 kids 9,8 and both ate with no problems. HIGHLY recommend a drink to go with it. Don't think could stomach a bar with out some milk or water but in a true emergency a great buy.

I purchased Mainstay bars for emergency use but opened a pack to try them as soon as I got them. They taste good and seemed to provide good energy. I wonder why they would put artificial colors in them that some may have allergies to. These are survival food; who cares what they look like.

I bought these to use as an alternative to rotating the 72 hour kits all the time. They taste like shortbread lemon cookies, actually very good. All three of my kids totally liked them, they are 6, 4, 2. My only complaint is that they are a little crumbling, but who cares if your starving!!!

mainstay food bars

I decided to buy some of these to keep in my survival packs and in my vehicle. I tried them first as I wanted something that would do the job and taste good too. These are really good.

Delicious and easy to store

These easy-to-store bars are delicious and melt in your mouth like creamy frosting. My kids LOVE them and they are now a staple in our 72-hour kits as well as on camping trips. I have also been giving them to my youngest son who is underweight. It's an easy way to pack some extra calories on without battling over food issues.
