Colorado pack packing
I used to camp with just using a hoody as a pillow, I have since upgraded to this. It does its job fairly well. Ordered the small for myself but upon getting it I gifted it to my dad and ordered the medium! I am a picky sleeper so this helps me out a lot.
However the pillow does take up a lot of room inside of your pack, but if you still rock the external frame pack like I do just strap it to the outside or throw it inside your sleeping bag and compress it. One more thing I recommend not storing it compressed and definitely unpack it right away when you get to camp it likes to puff up slowly.
