Buying Guide: How to Choose
-
Measure your usual group size
An 80x80 footprint comfortably fits a family or small group; solo trips may not need the extra size.
-
Check the waterproof backing material
A true waterproof layer, not just water-resistant, is what actually blocks dew and damp sand.
-
Confirm it's machine washable
Picnics get messy, so being able to toss it in the wash saves real effort afterward.

Can it fit a big group?
At 80x80 inches, it comfortably seats a family or small group, more than most standard picnic blankets.
