Half frame bags are ideal for gravel and road bikes, but work well on mountain and fat bikes as well. In my opinion, it works best if your frame is large enough that the half frame bag will allow you to still use at least one water bottle cage. If your triangle isn't large enough to run a half frame bag and still use a water bottle, you might as well just get a full frame bag. When taking photos for me to make a template, it would be best if water bottles are in the cages so I can work around them.
