These sheets have a fun design and after one wash are still fairly soft. I’m a hot sleeper and had no trouble with being over warm, just a nice snuggly, breathable warm. 
There are two things that take the review down a star, however, firstly  I ordered California King for my regular king bed and am so glad I did as they are a tight fit after just one washing. The mattress is pretty thick, so if you have a standard one you should be OK, otherwise I recommend buying a size up, especially if you like the sides to tuck under the mattress. 
Secondly the pillow cases are not opposing. If you care about the openings being on the outside of the bed, you’ll have to put up with the pattern being upside down on one. 
I cover my pillows so it doesn’t show, but it still bugs me a little.
