Mountain Horse made its name in cold-weather riding boots, and that is still where most of the range sits. The Rimfrost III, Active Winter Rider, Snowy River and Arctica are insulated tall boots for riders who keep going through winter, and several come in wide calf and shorter heights. The Veganza line offers a synthetic field boot and zip paddock boot for riders who prefer to avoid leather.

The apparel side is lighter than the boots suggest. Tack of the Day carries Mountain Horse tech tops such as the Tindra and Magic, the Tate Tech Fleece, fuzzy hoodies and sweaters, plus Matrix Tech Tights and Estelle Cargo Breeches, often priced well below full retail. Stock rotates as Mountain Horse updates each season's colors.

When choosing a winter tall boot, try it with the sock you will actually wear in January, not a summer one, and check that the insulation leaves room to wiggle your toes. Cold feet in a boot are usually a sign that it fits too tightly, not that it is too thin.
