What combination of factors makes the Boykin's coat a successful compromise for its historical workload in the humid South Carolina low country?

Answer

A coat that dries relatively quickly and doesn't snag excessively

The silky, medium-length coat is a successful compromise because it dries relatively quickly and avoids snagging excessively in dense underbrush, unlike a coat that is too thick or woolly.
