actually this Lezyne is better for fat bikes
I have one of these pumps. I like it, but it is large & slightly heavy to carry on a bike packing trip. If you were inflating tires frequently it might be worth it or in a group & carried one pump. When travelling by truck with my fat bike, the Micro Floor Drive XL is the only pump I take - it's efficient enough to use in place of the floor pump I used to take on truck-based trips.
