Product Insights
The Soris Knit Polo by Theory offers a sophisticated minimalist alternative to a traditional polo, merging a cleaner fit and lightweight knit with tailored proportions that enable tucking and layering under a blazer, but demands cold-water washing with a mesh bag and flat drying to preserve its soft, draping fabric and prevent shrinkage or distortion.
