Extremely pleased! Went on vacation for a week where the sun was fierce and the temperature was in the high 90s every day.The Amazon reviews are favorable but seem to be written primarily by people who received a free sample. I researched other sources and found a consumer report review of a couple similar products, though not this particular brand. The review of those products were discouraging, reporting that their infared camera recorded identical temperature readings with a standard wet cotton towel. I'm not sure if Chill Pal is an exception but they felt startlingly cold and not just "cool." Curious people in our tour group asked to touch the towels, wondering just how cool the towels really got and all responded with great surprise. Regardless of the actual towel temperature, it should be mentioned that these towels hold moisture and their cool temperature much longer than a standard towel, without being dripping wet like a cotton towel.Interestingly, our luggage was delayed so we were without our Chill Pals for the initial three days. I can not emphasize enough the difference the towels made!! The initial days were unbearable and exhausting, and we were unable to enjoy the tour activities. Two of my children suffered heat exhaustion with nausea. Having the towels enabled us to remain outdoors longer and enjoy walking around. I'd walk with the towels draped over my shoulders or arms, or when sitting, we'd drape them over our laps. While walking, we'd swing the towels against our legs, behind the knees for great relief.In constant direct sunlight, 98 degree temp, the towel began to stiffen after a few hours. Even then, I could wrap my hand in the towel and feel as though it were in a pocket of cool air. A water bottle or bathroom sink quickly replenishes the towel. The cooler the water the better, but even lukewarm water is sufficient if you wave the towel around in the air.It is important to wash the towel before use because it bleeds a lot of color. Even now, washing releases some color. (I bought blue towels.) Regardless, I have observed no color transfer on our clothing.The towels arrive damp but they are so because they've been soaked in a preservative solution, which is washed out with the recommended initial pre-washes. It's important not to store the towels wet later.Being on vacation, I hand-washed towels after each use and stored in hotel mini-fridge. It's not necessary to keep in fridge but it's extra nice! Some towels once froze, and we tried to force them apart. The towels started to tear and disintegrate. Once we noticed the damage, we ran water over the towels until they defrosted and released themselves. There was then no further damage. Do not intentionally freeze. The towels will be unusable until they defrost.I was nervous about how to transport the towels home since they no longer have the preservative and so mold if stored not completely dry. They hold moisture for exceptionally long so I had more reason to be concerned. I hung all towels up on pants hangers outdoors in direct sunlight and surprisingly, they dried completely after just 3-4 hours. They do dry stiff as a sponge dries so I didn't try to fold them. I just lay them flat in a large suitcase. I'm doubtful that they'll dry that quickly indoors or in the shade though. Before the trip, I did partially dry them in the drier and lay them out flat as I could to complete drying. I imagine tumble drying them completely will leave them in an unpackable form.One confusing point is that the Amazon site repeatedly emphasizes a full refund with no return necessary, but when I called Amazon, they are insisting that I return the damaged towels. I can not return them dry because they are flat and hard, unfoldable, unrollable. I will have to wet and roll to fit back in the tube. They will most definitely arrive molded. I went round and round with the Amazon rep but the rep wouldn't hear anything of it, and didn't care what their site stated.Photo taken of flat, stiff, dried towel. Towel is being held still by one hand, not being waved around. When dried, it is light and stiff like a thin sponge sheet. Previous reviewers have likened it to cardboard. I'd agree.Don't expect wet towel to feel like a cotton towel. Imagine a thin, smooth, soft sheet of foam-like material.
