I ordered a "heatshield" sunshade for my '15 Outback. It's lightweight and rolls up into a compact roll with a velcro tie. I thought it was extremely effective for my Outback. I just got an email from the company that they now have their Ascent version ready to go. The picture on their website doesn't show it but it has the cutouts for the Eyesight cameras and is custom fitted for the Ascent. Even though I have the Subaru OEM version, I will be purchasing this one. Easier to throw in the back, much lighter and less bulky to move and store.
