Long trips can be a pain. I personally prefer to sleep through them. You are going to need a travel pillow to do that comfortably. The HoodiePillow has you covered. It is an inflatable travel neck pillow for air travel, road trips, lunch break napping, or any time you want to get some rest.
The HoodiePillow has two drawstrings to adjust to head size and level of comfort. It has and inflatable neck pillow insert that can be deflated and folded for easy storage. You can get one of these for under $20.
