Safoner Waterproof RV Vent Insulator and Skylight Cover with Reflective Surface, Fits Standard RV Vents- 14x14 Inch (1 Pack)

It fits perfectly. It doesn't not come loose when traveling. It does a great job of keeping the heat out. It's easy to install and remove.

These work great so far. I have used this 2 pack in two of the four ceiling panels (the ones without the fan in it) and they have been working great in keeping out the cold. I think that these should keep the heat out during the Summer. These were very easy to install and they stay in perfectly.

Bought these (along with a shower skylight cover and two door covers) in hopes of avoiding the purchase of a second A/C unit. I wouldn't say that these are appealing to look at, but - so far - they're doing the job.Fit is decent and it has certainly stayed cooler in the bedroom than it was before. We'll know for sure as the summer continues to heat up!

Seem well made and blocks out the sun.

I like the change from the foil versions which as they age flake all over when taking out etc. I am not sure why there is a zipper and these seem to be slightly larger than other makers which certainly keeps them in place but also makes is seem like a less than perfect fit. So good for what I needed, not ideal for aesthetics,

This is the perfect option for rv vents. We have a vent right over our bed that let's in too much light early in the morning. This cover squeezes easily into the vent hole to help keep the light out. We also go camping when it's cold out and this helps to keep the heat in the camper. Highly recommend this cover!

Helps keep the heat out very very well. Here in South Texas we are concerned with keeping heat out - between this item and covering the windows in my travel trailer, I'm not longer fighting Mr. Sun.

Installing these kept camper so much cooler in the summer and no cold drafts in the winter
