Most swing covers advertise waterproof or water-repellent protection plus UV resistance (some specify UV30+), and general weather resistance to rain and snow. They also protect against dust, bird droppings, and tree sap. Manufacturers may enhance water performance with taped seams or PA/other coatings to reduce seepage.
Weights vary with size and material, ranging in the provided listings from about 1.5 pounds up to 13.67 pounds. Many common covers fall in the roughly 3–10 pound range depending on fabric density and additional features.
Common waterproofing treatments and linings include waterproof PVC linings, PE/plastic coatings, PA coatings on polyester, PE coatings on Oxford fabric, and taped seams to reduce water penetration.
Many covers are lightweight and designed to slip on and off easily. Typical care instructions in listings are spot cleaning or wiping with a damp cloth. Several products also note they fold compactly for convenient storage when not in use.
Some listings specify fabric ratings such as 600D Oxford and fabric weights like 180gsm polyester (often with PA coating). Other descriptions refer to 'high-density Oxford' or coated waterproof fabrics without providing additional numeric ratings—check individual product specs for exact values.
