Our Lounge bags are made of 100% Quality Nylon. Not Polyester. 

Nylon and polyester are both synthetic fabrics, but nylon production is more expensive, which results in a higher price for the consumer. Nylon also tends to be more durable and weather-resistant, which is why it is more likely to be used in outdoor apparel or gear. Both fabrics are flame retardant, but nylon is stronger, while polyester is more heat-resistant.
