If you want US-made only bedding, I would stick with Supima cotton since that will be the highest quality cotton you can get from the US. I've noticed that many 'Made in America' brands that market their sheets tend to either only use long-staple cotton or just say it's high-quality premium cotton without saying that it's Supima or extra-long staple cottons. Generally, though, if you look around at most US-made brands the vast majority won't just come out and say 'this is Supima cotton' they merely imply it. Long-staple cotton is better than regular short-staple Upland cotton, sure, but ELS (or Supima) cottons are far superior and are what you will want to go with if you want the nicest, longest-lasting sheets that you can get. The only brand I managed to stumble on recently that outright says on their product pages 'Supima cotton' is Wright Bedding, so I would start there, honestly. Good luck! :) More on reddit.com

Macy’s Hotel Collection are amazing—Supima Cotton Percale Weave. I have slowly converted all my beds to them. More on reddit.com

Pottery barn has great sheets that I have recommended before. Not cheap, but mine have lasted 4 years so far and they have only gotten better with time. Mine are 400 count percale, but last time I looked they also had some 300 count organic cotton percale sheets that felt really nice. I sleep hot as well and they do a good job dissipating heat in my opinion. More on reddit.com

I have percale from Casaluna ($80 at Target). They're phenomenal and I adore them.

I've also enjoyed Stone Washed Percale from Tommy Bahama ($40 at Marshalls) and Cotton Percale from Threshold (around the same price, Target).

There is a noticable difference in how the Casaluna sheets have worn. They've maintained their stiffness while still being soft, while both of the cheaper sets wear into extreme softness after about a year. This isn't a bad thing, bit it's not what I personally look for with percale sheets.
