Change your fabric to WHITE or BLACK Challenge Sailcloth's ULTRA weave fabric which is super tough, tear resistant and lightwight. Here's an excerpt form their website,
 
"ULTRA™ weave is constructed with an optimal blend of UHMWPE & high-tenacity polyester. The tight weave is laminated with an eco-friendly adhesive to our revolutionary Challenge RUV™ film. The result is a textile that is incredibly strong, lightweight, and waterproof to 200 psi. ULTRA™ performs in the harshest environments, in both sub-zero and tropical climates."
