Flex Vest - Black with Cooling Packs

This vest has a great fit, very stretchy and fits snug against the body. I was worried it would be too big for my small 11 year old but the size S works great. He is not able to sweat so wears a cooling vest for gym class and any other times he is active or in warm weather. He loves the style and it does keep him cooler than his previous vest, however, the pockets for the cooling packs do not secure at the top so he is constantly having the cooling packs slipping out during activity. I will be adding some velcro to help keep things in place. Otherwise an overall great vest. I appreciate the option of something a little more "stylish" for people that need them for everyday activities.

I contacted Glacier Tek directly and I was welcomed by Zack Best. He was very professional and listened to my concerns and about injuries that I had sustained in the past. I have been a strength athlete for over 20 years and I was hurt pretty severely at the end of 2015. I was hospitalized and a part of my condition today that I have to avoid is overheating. Living in Florida does not make it easy. I researched these vests and with the help of Zack Best I am back in the gym with my vest five days a week. It has been a lifesaver! I recommend this vest and whole heartedly believe in the company. Thanks again Zack! I will refer you and your company to anyone who asks or needs relief from the heat.

Cut/ fit great, concept of keeping core a certain temperature is great, but didn't keep me cool enough in hot weather.

I'm an HVAC tech by trade here in Texas. While I haven't given this a go here in the heat of summer yet, I'm confident that the vest will definitely help at least keep the edge off for quick trips in to the attic.
I've worn it around the house and during garage work so far and it is super comfy and stays dry. I've been impressed with the amount of time the vest stays cold when not being worn. I had this in my hot van for a couple hours, got in the van to go home and it was still very cool.
Keep in mind, most of the time these are not like ice packs out of your freezer (although they are when straight out of the freezer) most of the day they'll be around the 50-60 mark. If they're partially frozen, we're told they maintain around 59'. Seems about right. Where as a ice pack seems to be either frozen / super cold or warm. So, the glacier packs, while not as cold seem to hold the cold for much longer.
I'll be interested to see if this will hold up to the rigors of HVAC work in the attic which involves some laying on your back and scooting around.
I did go ahead and order an extra set of cooling packs so I can keep them on a rotation during the summer.
I'm pretty sure this is going to be a full-time piece of clothing for me this summer.
Great job. guys.

The vest fits comfortably and the 12 cooling packs stay sufficiently cold to keep you comfortable for about 1 1/2 hours in 90 degree heat. If the pockets for the cool packs had a flap or Velcro closure to keep the packs secure, it would have received 5 stars.

So I'm an auto mechanic. Today was 100 degrees with 110 heat index. Yes I was sweating on my face and arms as you would expect BUT I wasn't dealing with heat fatigue. This evening at 5:30 I was still feeling good. YES you do have to put one pack in the freezer while the other pack is being used. In 100 degree heat, putting the packs in the fridge isn't enough. I burned through these packs in about 2 hours and the other set was ready by then. This vest is VERY flexible and comfortable to wear. I really bit off a little much because of the price, but in the end, it fits under my work uniform shirt and is very comfortable. I wear a regular t-shirt with it to help keep the shoulders cleaner. I'm going to have to say this is a GOOD product and it really works.
