The beach is the one place we wouldn’t recommend that versatile, all-purpose blanket. The weather-resistant backing is good for sitting, but the fabric side is a problem. Once it’s wet, sand is challenging to remove from fibers like fleece. If you can wash it in the machine, most will come out eventually, but many weather-resistant materials can’t go in the washer. Instead, we recommend a lightweight polyester blanket. You can easily shake or wipe sand off this water-resistant material, so it’s ideal for sitting or lying at the shore. It won’t provide much padding or warmth, so if that’s a problem, bring a washable blanket to keep yourself warm and a yoga mat or other base to cushion the blanket.
