The case and zipper are very sturdy, and I appreciate how easy it is to adjust the thickness of the pillow by just removing or adding hulls.
I usually sleep on my back, and ended up removing about half of the hulls to find the pillow density that feels just right. As I removed the hulls, I was impressed by the uniform consistency/quality of the hulls themselves (same color/size, no shredded bits or dust).
This pillow feels much cooler than other types I’ve tried, so no more flipping the pillow in the middle of the night to try to find the cool side!
