Perfect!
Color: Grey, Style: 2 Blocks
Perfect size and very stable and soft. This isn’t cheap and wobbly like some blocks — this is thick and my husband who is 220lbs uses it with no problem! Love it!

Good comfy product, good quality and aesthetic color
Color: Grey, Style: 2 Blocks
First yoga blocks I buy for home. Excellent texture and quality, they are really comfortable for support. The grey color is very aesthetic, I think the shade will be great for hiding any stains or dirt over time. They look expensive and I love that. I tried scratching them with my nails and the marks completely disappeared after a few minutes. The engraved logo is a nice plus. I love that they’re a bit taller than average blocks. The grip is good.

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.
