Question: does anyone know if u can refreeze these in ice and ice water i currently have some like this and these look like mine
Document: My husband has used this for 1 summer now, and it has held up well, no leaks, no fabric tears. The phase change &#34;ice&#34; is amazing because it doesn't feel really cold to the touch, but can absorb a lot of heat and cool you down.
it is much heavier than i anticipated. i am still trying to decide if the cooling will offset the weight.
Works great and just as described. Packs last 4 - 5 hours and keeps me very cool as I work outside all day.
Back cooling is more productive since it is easier to fit tight against the body and there is generally less fat there. I still sweat wearing this in hot weather,  but this decreases overheating over not wearing it. Wonder if side panels would be more effective than front panels due to less insulating fat there on most people?
Appears to be good quality vest material. Cooling packs &#34;freeze&#34; in refrigerator. Reasonably comfortable to wear and lasts surprisingly long. Velcro strips could be made longer to fit a wider range of sizes. If in doubt, order a smaller size. Velcro strips do not cover the lower end of the &#34;large&#34; range well. For this to cool properly, it needs to be in very close contact with your body.
Answer: no
