It sure doesnt look or feel like its going to work very well. BUT IT DOES A GREAT JOB!! I was impressed at how much it grew once it had soaked. The cool lasts for awhile and comes right back once its rinsed out in cold water. I store it in a ziplock in the fridge for the next day.This is a great little accessory. It stays cool for days after you get it good and wet. I wear it around my neck constantly in the North Carolina heat. The seam can be a bit irritation, and I wish it was wider, but for the price, you can't go wrong. I'm about to order a few more - will be giving them as gifts.I’m glad I discovered these bandannas through a couple different friends. Excellent for keeping cooler on the hot summer days that seem to be getting hotter. The black also looks nice and matches anything. Have given as gifts and Will definitely purchase again.It was cheep and it works, though the color is way off from what the photos showed, its more grey then blue.These 100% work, they do what they claim, they are essentially perfect little personal coolers. Why are the all ugly? Why can't they make just like, one that isn't just hideous???I think this cooling scarf works great. I have to wonder if the person whose negative review I saw was using it correctly. You need to soak it in cool water and then massage the cooling gel around so that it expands along the length of the scarf. Then squeeze out any excess water and wear. I found it worked wonderfully all day while the AC is out at work. When it warms a little I flip it over so the opposite side is against my neck. I flip it every hour or so, but only had to soak it once a day. It makes me feel so much cooler, and at this price it's a real bargain. Of course at this price it doesn't look like an expensive silk scarf, but I wasn't expecting that. I am going to buy more so I can rotate them.These cool neck things may look really stupid, but they work really well...They are a great price, they're easy to use, they can be reused in infinite number of times, And they are magical when it's really hot outside.They're very handy for any type of outside activity while it's really hot - hiking, gardening, camping, yard work, etc...You can wash them by hand with just a little bit of dish soap and hang them to dry. I would definitely recommend these to everybody, and I actually do!They aren't the most attractive thing to wear, and they do look kind of silly, but it's worth it!Works greatWhen my MiraCool arrived, the padding inside the middle section,, which I imagine is there to hold water, was all shunted up to one end and I could not redistribute it along the section.Deberían de fabricar sin el gel y agregar a la parte frontal material absorbente para sudoración. No siempre se usa en construcción donde tienes a la mano agua fría para humedecer y activar el gel, el uso que le doy es en campo.Product works just like advertisedOne of the 4 was poorly sewn allowing the cooling gel beads to pour out before even being used for the first time.Very cheaply made.Started leaking a strange substance almost immediately. I threw it out. I would not recommend this product.
