Top stay-in-place fitted sheets from Nestwell

Hello everyone, I have been searching for a few durable bed linens recently. Someone mentioned the high quality fine fabric sheet sets by Nest Well, specifically their well-known fitted sheet lineup. I'm checking where to buy these Nestwell sheets for queen size or queen size these days.
 
In addition, is there any update on what happened to these Nestwell sheets or if Nest Well is still selling them? I really liked their True-Grip fitted sheet design where the sheet stays firmly in place without slipping. If you know where can I buy sheet sets that feature the True Grip fitted sheet, please let me know!
