I have an Outback Outfitters Gore Tex ankle length riding rain coat from Stampede Tack in Cloverdale. It keeps me dry about an hour. It is light weight and dried in the barn overnight. I chose it over the heavy traditional waxed cotton raincoats.
An endurance rider friend once loaned me a great piece of gear for a rainy ride. It was a neoprene skirt that went on over your breeches and covered your thighs butt and saddle. Warm waterproof enough air flow you didnât sweat up, and stayed in place better than a raincoat. It was similar to a kayak skirt and nasty to walk around in but wonderful on the horse.
You can also put a keyhole rainsheet over horses butt saddle and your thighs.
Other than that in my experience morning rain will taper off mid afternoon and likeliest dry moments are just before sunset.
Trails under conifers stay drier.
Wool and some microfibers have wicking and warm when wet properties. Donât wear any cotton clothes or down jackets.
Get a wool cooler blanket for the horse. A wool cooler dries a wet cool horse better than fleece. Fleece is great for a wet hot horse.
