Fits 1-4 Flakes of hay.
2" Holes are great for bigger muzzles or for containment of your hay.
1.5" Holes to limit intake but still contain hay within the net, great for your average horse.
1" holes are great for trailering and to slow down intake even more.
Heavy Duty is the same great net just a heavier mesh, great for that horse who is a little "rougher" on things or who have figured out how to chew through other hay nets.
Fine for all size horses.
