The MOLECULE Gel Memory Foam is a comfortable pillow to sleep on. You can simply unzip the cover & remove or add shredded foam for a customized fill to fit your sleeping preference. How cool is that? They are pretty lightweight. Easy to travel  with as well. My favorite thing about this pillow is that it’s washable! I sleep with mine every single night. I noticed it helps me fall asleep faster. I highly recommend this this product.
