I love these hybrid pillows better than the standard Casper which I also own. For side sleepers like me, the hybrid has substance and is also fluffy keeping a good neck alignment and happy ears.  Highly recommend this pillow. Getting great sleep and waking up without a sore neck or sore ears. 
They look great in my silk pillow cases and they never need to be fluffed as they maintain their beautiful shape. Kudos to Casper!
