I have the Rambo fly mask which has been brilliant for my mare.Had the last one 4 years before deciding I liked the newer design better - it really keeps the mesh away from their eyes.
I don't like any with elasticated noses, seen lots of horses with white marks where their masks have been too tight.
Absolutely without a doubt Equilibrium field relief hoods.
Not only do they protect from flies but UV aswell with for our uvietus sufferer is a life saver.
Ditto Equilibrium. Have never found the elastic too tight(4 horses on the yard have them) & find it makes a better 'seal' round the jaw than Horseware ones have with just Velcro. Expensive but last a long time&velcro v v
sticky!
