I am writing this review in late February, and the weather is very cold. It's been a week since I started using ProAir Sheet, and I've noticed a few things: 1. It's got a different texture and feeling than Premium Soft sheets. Whereas premium soft sheets are very silky and smooth, this sheet has a little bit of texture, perhaps a little bit jersey-like but not overtly so. Still, it feels very comfortable on my skin. 2. I found that this sheet retains heat more than Premium Soft. This was good for me because, despite being thin, the sheet retained heat and kept me warm. Also because of the moisture-wicking capacity, I would wake up without feeling like I sweated. One thing I am curious is how this sheet would feel during the summer. I'd be happy to update my review accordingly. All in all, if you are looking for a comfortable sheet with a bit of sporty feeling, this is for you. I like it, and so does my cat!
