Question: How do they get cold?  Should I wet them and freeze them?
Document: These didn't come with any directions and initially i didnt understand that they had to be wet. They soak up water and then that freezes - then they work great! Until they accidentally got wet, I didn't get it and I thought they were a dud. Othwerise, they are great- you can cut them into the shape you need, and they work fine, stay cold for a long time. we used them for a two day road trip.
Work great. These are amazing. Kinda magical. Wet them in the sink be sure to fill the pouches completely with water. Freeze. Done. Throw the sheets in your lunch box or cooler. They do not leak and stay frozen for hours. I use mine in my Yeti Roadie. They stay frozen all day.
These are amazing freeze packs. They really keep food cold and are easy to pack around odd-shaped food items. I use these everyday, and my lunch stays cold from 6:00 a.m. until early afternoon. Great technology!
Works good - kept the items cold for the trip in the cooler- but the material inside it can get squeezed out a little... so your hands and a few of your drinks might get a little slimey.It was cool that they came flat... and you had to soak them in water before freezing them. I am trying to dry them out to save them for later.
These freezer sheets are everything that was described on the website. I'm highly impressed with the ease and effectiveness of use. Trim to any size. Soak for a few minutes in water. Freeze and Use. They thaw dry! Refreeze and use again...and again. I used two small sheets in a standard lunch size soft cooler. Kept things cold for about 6-8 hours. I will be ordering more. Highly recommend.
I purchased these for an injury. Best ice packs ever. I was able to cut them in half and roll them into a towel to use as a neck ice pack. They stay cool for about 8 hours its perfect and I am able to get some relief fom pain.They also work great for lunches because they dont take up a lot of space yet stay cold for so long.I highly recommend this product, its versatile and works wonderfully
I used these in combination with a soft sided polar bear cooler. Initially the packs kept everything very cold for quite some time. Once they thaw out you do get a slightly slimy coating on things. In hind site I should have loaded the cooler, put it in the refrigerator and let it get really cold, then load the frozen packs into the cooler bag. Probably would have worked better than loading warm beer into cooler bag and then adding the packs.
These ice packs are easy to use, and of course, not messy because there is no ice to melt and get on everything. It works nicely to use for aches or to reduce swelling, and is nice to use to keep food products cold. They do not last a long time, so keep that in mind if using for keeping food cold on trips.
Disappointed. Came in a bag with no instructions. I think these may have been retuned by someone else. I am not sure what I need to do to freeze them
These worked out very well. They even absorbed water from melted ice I had added to the cooler. They can be cut to any size. You soak them in water and freeze them before use. A pack f 5 is a lot. I only needed 2 sheets for a 28-Qt cooler. When not in use, they store flat.
