Quality hide
Size: 2' x 3' (Oblong)
I've purchased 5 hides from different offerings on this platform. I keep coming back to these for my needs due to the quality and price. I also prefer the natural state these are in, compared to the dyed versions offered by others. Highly recommend by me someone who actually uses them for home bedding and camping bedroll purposes.
