Zero fill, or max 100gm is all I need. My blankets are still good enough that I don’t want to spend $300+ to get new blankets, and I’m somehow missing a sheet, and I suspect all 3 horses will need some extra protection at some point this Winter, and I’ve often wished I had neck covers for them all at one point or another most Winters. Cold rain and sleet are the bigger issues over snow here, but snow here is also wet.
Detachable neck is a requirement, as there will be other times the sheet will be used where an attached neck will be too warm.
I’d also rather not spend $200+ on a sheet
