I wear a boonie hat + this when I'm out doing yard work. My neck has suffered too many burns over the years and I wanted a way to protect it better. This covers my neck pretty well and it does stay rather cool but only when contacting a breeze, i.e. walking, riding a mower, jogging, etc. If you're totaly still and not moving, it can feel "warm" since it's just sitting there on your skin.

It stays moist for a long time, about 2 hours. What I like most about it is it's versatility as shown in the ad. I like mowing with it and pulling it up over my face when I his ride over a dry soil or leaves as they kick up tons of dust.

Overall I really like the product, I wish it had a "tail" end that could tuck underneath a shirt for 100% neck protection but that's really nitpicking overall it's a solid buy on sale and helps protect me in a number of ways.
