Excellent pillow. Already had the smaller Panda pillow but this hybrid is so much better. Only flaw is no removable cover so I can wash it!  Luckily my normal pillow cases fit. , but there was a removable cover for the smaller one so lovely and comfortable pillow  but why no cover with this one?  Especially as it cost at least double the other pillow. I assume you sell the hybrid Bamboo cover as an extra but no thank you, should have come with hybrid.  Having said that the pillow is great,  I now have no trouble  sleeaping
