Matador is a small business that creates innovative, durable, and long-lasting travel and outdoor products, and in fact, the Pocket Blanket was the first product they ever created.
I have this blanket and it really, truly fits in your pocket! When folded completely out, it fits two people lying down and would probably fit up to four people sitting. It’s super thin without being flimsy, and any water, dirt, or sand just rolls right off of it. I did get some sunscreen on my blanket the last time I used it, but I threw it in the washing machine when I got home and hung it to dry and it was as good as new. I took this to the beach this summer, and the stakes in the corner and the sand pockets were super helpful at keeping it from flying away in the wind. It also has a very subtle stitched guide on the blanket that you follow to fold it back up to pocket-sized. This blanket is so great and is a must for spontaneous hiking trips, beach days, or even a date in the park.
Get it from Matador for $34 (available in three colors).
