We have not done an extensive test of fat bike fenders yet. However, we have gone through about a dozen fender options and landed on this setup below. We find it keeps about 90% of the mud and water off us. It's not as effective as “rainbow style” fenders that cover half the wheel and keep about 99% of the water and mud off you. However, we have not found that style fender that works for fat tires and is durable.
Our solution comes in three parts:
1 - Portland Design Works Dave's Mud Shovel - Front2 - Portland Design Works Dave's Mud Shovel - Rear
The combo runs about $50-60. Installation is easy and takes about 10 minutes. No tools are required, but scissors are useful for trimming zip ties.
We recently ordered the SKS models, which look similar. We will report back shortly on their performance compared to the Mud Shovels.
Most of the front tire is not covered. At low speeds, this is no problem. Once you are going above 10 mph, some water will fly back at you.

Portland Design Mud Shovel with the Fifty-Fifty does not give perfect protection. It sheds about 90% of mud and water.

The Mud Shovel cover about 1/6th of the wheel. Not perfect, but it does protect you from most flying water and mud.

The Mud Shovel gives good, but no perfect protection. It breaks away from the snaps in a crash or if you put your leg over it. This is a good thing as it protects the attachment system from snapping.
