The Tack Trunk, the only horse apparel and tack shop in the greater East Hampton area, is on Main Street in Amagansett. The Tack Trunk has been in business for 16 years. Erica Walter, an East Hampton native who grew up riding in Amagansett, bought the business a few years back. This shop is fully stocked with items for equestrians to horse lovers, from brushes to riding jackets, jodhpurs to horse treats. It also carries a few luxury equestrian-inspired handbags, clogs and accessories.
