I personally actually like Shedrow blankets (well, not the second one you linked to, but most models). I think the sizing can run a bit inconsistent though, which can make for some disappointment.
I am a baker hater (gasp, oh no, I said it on a h/j forum. I will probably be tarred and feathered now). I find them to fit very few horses nicely in the shoulders and neck. The belly straps come undone all. the. time. And the heavy weight ones are the most shavings attractive thing everrrrrrrrrrrrrr (oooops, sorry that was all my rage coming out).
So when I needed something in that weight range I absolutely refused to buy a Baker (or, even have one given to me, as they also shrink, and the barns I work at would have had a big supply for my midget). I went with the Shedrow West Palm. It was a good blanket…not quite as warm as the Bakers, but definitely much warmer than a regular sheet. I used it both with his (again, Shedrow) sheet underneath, or on it’s own, no slipping or rubbing (caveat though, my guy was pretty narrow in front, it might not work as well on something big fronted). It definitely did not attract shavings…hooray!. It’s not a terrible option, especially as it sounds like you just need something for a bit. That said, I picked mine up at like half price…so I’m evaluating from that perspective.
This was all before they came out with the heavy plaid thing. I’ve seen them but haven’t had the experience of caring for a horse wearing one, so I can’t really review.
