Why Many Brands Also Consider Manufacturing in Vietnam

In recent years, many apparel brands have shifted their production focus from Europe to Asia in search of competitive advantages such as cost efficiency, scalable capacity, and access to advanced manufacturing ecosystems. While China has long been the dominant manufacturing base, rising labor costs, trade tensions, and supply chain diversification strategies have driven brands to explore other Asian hubs that can offer both quality and flexibility.

Among these Asian alternatives, Vietnam has emerged as a strategically attractive choice for global apparel and activewear production. Several factors contribute to this trend. Vietnam’s participation in major free trade agreements  including the EU-Vietnam Free Trade Agreement (EVFTA) – helps reduce or eliminate tariffs on exports to key markets such as the European Union, making Vietnamese‑made garments more competitive internationally.

In addition to trade advantages, Vietnam offers a stable political environment and business‑friendly policies that support long‑term partnerships and investment in textile infrastructure. Its proximity to major raw material suppliers – especially from China and other Asian producers also helps reduce lead times and logistics costs compared with more distant manufacturing locations.

Besides, Vietnam’s garment industry is backed by a large, skilled workforce experienced in performance apparel and technical construction, capable of handling advanced techniques used in activewear production. Major global brands have already established significant production footprints in the country: for example, Nike produces a large portion of its global footwear and apparel in Vietnam, while Adidas, Lululemon, Under Armour, Puma, The North Face, and On Running also rely on Vietnamese factories for key parts of their collections.
