Durable polyester fabric: made from polyester, this seat cushion is durable and tear resistant, washable, and lightweight for easy transport. Portable and easy to use: lightweight design folds compactly for carry in a backpack; provides a soft, dry place to sit and offers more convenience than a blanket or towel. Protects your clothing: helps keep your pants clean from dust and water when you sit down on ground surfaces after sport or outdoor activities. Waterproof and moisture resistant: the folding seat cushion is waterproof and moistureproof, helping to keep you dry and warm in damp or chilly conditions. Practical use scenarios: After a run or workout, sit on grass, track, or concrete without soiling your clothes. Take it on camping trips, picnics, or outdoor events where seating on the ground is common. Use during beach or park outings to stay dry and comfortable when resting between activities.
