Portable fenders

I sifted thru 200+ posts in this group and couldn't find anything on fenders. What plastic portable fenders has people used and how well do they work. I won't be flying anymore I doubt since I am retired but still might want the option of taking them off. I saw somebody suggest ass savers brand. On the rear probably looking for something that attaches to the seat post. A pic would be nice

 

Thanks

I haven't used these (actually they're not yet on the market) but the concept looks good:

That looks good for roadie bikes but looks a little bit tight for a gravel bike.

These come in wider sizes and seem to be in stock though it looks like they require stays:

Portland Design Works origami rear fenders are pretty good and don't slide back and forth as much as some I see other people running.  I've had the same one on my fat bike for almost 10 years.

Up front I like a mucky nutz thing just to keep stuff out of my mouth.

I've had a few Ass Savers because they fall off and I don't notice.

I've had good luck with the SKS X-TRA-DRY XL seatpost-mount rear fender.

 

The downside to a seatpost mount is that it doesn't protect the seatpost insertion point.

 

If your transport method allows something more permanent, the coverage of the Gravelhugger looks good:

Ass Saver fan here on my 2018 Diverge. I've not had them fall off but I am not riding a lot of really harsh gravel trails. They made it across Iowa this past summer no problem and are flat and were easy to throw in my duffle bag. they are pretty easy to take off and replace. 

I use the SKS Speedrockers, which are designed for gravel bikes.  Pretty easy to mount, adjust, and remove. Good for tires up to 42mm.
