Trek Puerto Rico Racing 2023 Back Wall 10 x 10

Canopy back wall.   400D or Mesh . Printing faces inside.

The mesh picks up the light differently, and packs up smaller.  It is see through.  And lets the air through better than 400D.

You can see the difference in the photo... Bike House is mesh, SSB is 400D

The PEDAL Industries wall is also mesh.
