The Gap's attempt at a premium fitness brand was well executed but unfortunately, Hill City didn't take off as planned. The company announced it will be shutting down this month, offering 30% off sitewide. The brand's offerings mixed technical performance with minimalist design aesthetics while boasting features like four-way stretch and water-resistant fabrics. 
For the time being, the company plans to restock their popular styles as well as stock new styles before fully shutting down operations.
