I love them but a determined horse will find the head easier to shift than a proper hood. I dont use the 'heads' for that reason as I have not found one that fits well enough to stay in place without a headcollar
For those who arent sure about the face covering I really like the necks they do too (there are two types - a neck and a neck with a bib and 'girth' type band, the latter is much better as its a stand alone item as opposed to needing to be fixed to a rug) the neck does up just behind the ears reasonably securely and keeps the horse pretty clean with just the face exposed
Very competitive prices and really quick service. They've got an outdoors one currently in production too apparently. They're on Facebook and seem to have loads of positive comments. Mine fits my mare so well and looks fab!
