Grass is rarely as dry as it looks. This blanket has three layers: soft fleece on top, a little padding in the middle and a waterproof backing underneath, so damp ground and sand stay on the other side. Opened out it measures 200 × 200 cm, room for four adults and the picnic. It folds along its own lines into a neat roll with a flap, a strap and a carry handle. Shake off the sand, wipe the backing with a cloth and it's ready for next weekend. Good for beaches, parks, campsites and festival fields.
