Carefree's two piece fabric construction is superior to brands using a single piece, single weight fabric for the entire canopy. The final wrap of the awning in the rolled up position (the Weatherguard) must be strong enough to protect the canopy from the environment. That's why Carefree canopies feature two piece construction with the most durable vinyl specs in the industry. No other awning manufacturer provides this measure of quality and rugged dependability.
