Cabeau Evolution S3 Travel Neck Pillow

This pillow has a few unique attributes that make it perfect for an airplane; but the most obvious one is its strap. You can attach the strap around any chair or headrest to keep it comfortable and stable as you sleep. Additionally, the microfiber is breathable and cooling, and it also has a chin strap to help support those who sleep with their head forward. Another perk for the flier: It folds down to half the size into its included carrying case, and the case itself is made to fit snugly around suitcase handles.
