I am in the process of making my own gravity water filter out of a platy big zip bag and think this would be a good option as a pre filter. Has anyone ever used the duda diesel 1 micron bag as a pre filter setup? If so how was the results or is there a better option?

If you can get your hands on the silk bag, it will be much lighter and less bulky. But, it's more costly. They work fine, once saturated.

Do they also make the silk ones? What's the micron size on them?

I have used the duda diesel as pre-filter for years and it works great

I've used the Duda Diesel filters for quite a while now but will often just take a small metal coffee filter when I know the water in the area will be running pretty clear. The Duda Diesel filters work well for me as well, however the dirt does stick in them, so I generally toss them out after a trip or two. I always cut mine down quite a bit (as shown in one of the links provided above) which makes them lighter and a bit easier to handle as they are quite large.
