While they're meant to allow your horse to cool out at a more healthy rate after a workout, coolers also function well as an extra layer of warmth under a winter blanket. Anti-sweat sheets are great for days that aren't quite cold enough for a thicker fleece cooler. These sheets are mesh & allow air to move while your horse cools down and help the coat dry out quicker after a bath. Use an anti-sweat sheet underneath a thicker cooler for the most comfortable & dry combination for your horse on even the coldest days. They're not only for the winter, so explore all the options as your horse may benefit from the use of a cooler even in the spring & fall. While cooling down, be sure to add some soothing liniments to your training routine.
