Review on RTop Soft Silicone Controller Cover Skin with Anti-Slip Grip for Xbox Series X/S Controllers (Includes 8 Thumb Grip Caps) by Nate Edwards

I wasn't sure if I needed these, but now that I've got them, I won't go back. As a result of using this product, I found that my thumbs no longer slip around and mess up my gameplay. These silicone covers fit perfectly on my Xbox controllers and allow me to play for hours without hand cramps. The texture is perfect, too - not too sticky, not too slick. My only complaint is that they are a little pricey, but in the end, it's worth it for better video game performance.
