fit, fittings, ease of use absolutely none
I work for a large UK stud, I bought one of these for my horse mostly because it was the cheapest I could find (!) am so pleased with it I have since bought a further 7 for the stallions I work with. Cannot recommend this vest highly enough.
fab - saves fine skinned tb's getting bald patches none really - washes well, does what it says
as above, cheaper than robbies, my boy has worn his every day since the temperature dropped, he has ripped it on something, but easily repairable. washes great :-)
