I only uses those sleezies for holding down a mane, after I have banded it for a show
I never have had a horse rubbed by a good fitted blanket, including one in slick show coat condition
I would not use a blanket with a wool or felt liner, as you will get friction, since it can't move freely. A good quilted well fitted blanket, with tough water proof outer shell works great for me, and I often have my horses turned out with them, in pastures that have trees. I do not like using any hoods on turned out horses, because even in stalls, at times, they get shifted around, so the horse can't see, and that includes those slinkies.
More than once, I have gone into the barn at a show,e arly in the morning, to find someone's horse 'blind' or have that eye hole moved, so the horse has one irritated eye
Yes, I don't want one with a face or neck part to it for those reasons as well, just the shoulder cover.
While I agree the wool can contribute to friction, we use them ever so rarely that I am not concerned at the moment. We also used them typically when the horse is already wet, and the wool worked wonders to wick that extra
moisture away to help the already cold horse get warm faster.
We also have used them for multiple days in a row in winter, and had no issues on friction. He just definitely has a very thin summer coat, and the wool catches it more than it would a winter coat.
If we find as time goes on that this gelding needs more frequent blanketing, then I likely will look into different materials. :)
I may have also had the front too tight, after having read some about blankets this morning. (He is newer to us, so I hadn't blanketed him ever before, and it seems to be a bit of a learning curve each time lol).
