HANSSHOW Sunshade Glass Roof Sunshade Compatible with Rivian R1S, UV Blocking/Heat Insulation Cover Set Foldable Sun Shade Compatible with Rivian R1S 2022 2023 (1 pcs)(No Clips/Suctions Needed)

not that many options for sunshades for the R1S yet so was happy to find this one that fits in the glass sunroom for 2nd row. Rivian cabin often gets really hot from the radiating heat from the sun. You can tint it for a few hundred bucks but this is much cheaper and more effective solution.Comes folded in a bag but unfolds by itself. Better to do it inside the cabin since the thing is pretty big and barely fits in the door if unfolded. You basically unfold it and push the edges around the space between the glass and the trim of the car. It comes with a trim removable tool but I didn’t want to mess around with prying open trim. Also comes with plastic clips to keep it attached to the trim but I didn’t need them since once you get one edge in between the trim with your fingers, you can work the other sides into the glass and it fits well without the clips.After leaving it in the sun, definitely can feel the difference in the cabin temperature, less radiant heat for sure. It does block the visibility quite a bit but i guess that is the whole point of the sunshade. Will use this in the hot summer months and take it off during the winter months.

Made a significant improvement in cabin temperature when the sun is out. I only plan to keep it up during the spring/summar. It fits well but there is minor sagging which didn't bother me because of how much it helped with the temperature. Also no clips were included which I didn't need anyways. Well worth the money if you live in a warm and sunny area.

I was pleasantly surprised to see the package included a trim tool to make it easy to gently pull back the headliner and press the sunshade into place. I could tell immediately less heat is hitting my head, which was the main objective for me!
