Thanks @fourfillies I forgot about those! A client did have one a few years ago and it seemed great (but fit large if I recall correctly?)
@Simkie Her BR has the similar idea to the Vari-Layer, but a 500. Static guard is what my client uses, but I really hate spraying chemicals in the barn as I am chemical sensitive, but that is an option, and might be what I do. She has pretty much free choice hay when cold (unless it blows away), but she won’t always leave her shelter to eat, and I don’t want to feed her in the shelter as then I don’t think she will share the space with her buddy. I just want her to be warm enough the odd cold snap, that she will venture out. She and the other chestnut that come inside, have very little hair this year: I have no idea why and it is not normal for either of them, so maybe a 400 plus a liner for these odd cold snaps make sense?
I am not liking climate change.
