Keeps me cool!
Color: Blue/Grey/Green/Pink
These cooling towels are wonderful. I use them when I play pickleball. I get them really wet and then squeeze out any excess water. When I put one around my neck it is not dripping soaking through my shirt. I can use it to wipe my face and keep me cool. I can always add more water to it as needed. It is soft and the perfect size to wear around my nect.

Wet towels only
Color: Dark Grey/Grey/Brown/Black
Beware: these towels are supposed to be wet. They are meant to be soaked in water. If you soak them in water and then wrap them around your neck during indoor cycling, for example, they can cool down your neck and face perfectly.
They are still pretty good towels when dry, and they still cool the skin when dry. But they are not the best for wiping and absorbing sweat when dry. If you want something to absorb sweat, then cotton towels are better. You can still use this product for cool drying. However, this product shines when you wet it down and use it for cooling, rather than drying.
Overall, great product! Ivery soft and smooth on my skin.

Great cooling towel for the price!
Color: Blue/Grey/Royal Blue/Black, Color: Blue/Grey/Royal Blue/Black
This was a great find for outdoor running in Texas! The towel really kept me cool during my runs, and was very lightweight. It wasn’t too thick, but did dry fairly quickly, that’s the only reason I took a star off. I didn’t mind that much and just re-wet as needed! The price point is perfect and for that reason alone I would rebuy again! The colors were great, and the towel didn’t have any weird smell!

Sukeen [4 Pack] Cooling Towel (40"x12")
Color: Blue/Grey/Green/Pink
I recently purchased the Sukeen 4 Pack Cooling Towels, and they have quickly become an essential part of my fitness and outdoor activities. Here’s my detailed review of these cooling towels:
**Cooling Performance:**
These towels work incredibly well to keep you cool during intense activities. Simply wet the towel, wring it out, and snap it a few times to activate the cooling effect. The towels stay cool for a significant amount of time and provide instant relief from the heat.
**Material and Comfort:**
The towels are made from a soft and breathable microfiber material that feels comfortable against the skin. They are lightweight and don't feel heavy even when wet. The size (40"x12") is perfect for draping around your neck, over your shoulders, or across your head.
**Versatility:**
These cooling towels are incredibly versatile. I’ve used them during yoga sessions, running, gym workouts, hiking, and even while gardening. They are also great for cooling down after a hot day outdoors. The pack of four ensures I always have one ready to go, even if the others are in the wash.
**Durability:**
The towels have held up well after multiple uses and washes. The edges are well-stitched, and they show no signs of fraying or wear and tear. They maintain their cooling properties and softness wash after wash.
**Convenience:**
Each towel comes with a carrying pouch and a carabiner clip, making them easy to take along wherever you go. The pouches are compact and fit easily into gym bags or backpacks.
**Value for Money:**
This 4-pack is a great deal for the price. Having multiple towels is convenient, and they provide excellent value compared to buying single cooling towels.
**Overall:**
I highly recommend the Sukeen Cooling Towels for anyone looking to stay cool during workouts, outdoor activities, or hot weather. They are effective, comfortable, and durable, making them a fantastic addition to any fitness or travel gear.

Worth it if you’re going to be out in the heat for long periods of time!
Color: Blue/Grey/Green/Pink
These were a life saver during 90 degree heat for a golf outing event, being outside for 12 hours. They were a good size and versatile for the use—can be draped over the neck, tied around the head like a headband, etc. They stayed damp and cool for long periods of time but were easy to quickly cool again with a quick dip in some ice water. Definitely recommend!
