sunproof (comparative more sunproof, superlative most sunproof)

1. impervious to the rays of the sun
   • 1606, John Marston, The Wonder of Women

     There once a charnel-house, now a vast cave,

     Throws out her heavy shade, the mouth thick arms
     Of darksome yew, sun-proof, for ever choke
