Beyond the UK: Considering Vietnam for Performance Apparel

For many brands, working with a UK or European clothing manufacturer can be highly beneficial, especially if your goal is speed to market, smaller batch production, and close collaboration on design and quality. Local manufacturers allow for easier communication, shorter shipping times, and hands-on involvement in sampling and fitting sessions. This setup is ideal for brands that prioritize flexibility, rapid iterations, and maintaining tight control over production while testing new collections or launching limited runs.

However, if your goals shift toward scaling production, reducing unit costs, or producing large-volume collections, it may be worth considering manufacturing in Asia. China is often the first country that comes to mind for mass production, but Vietnam is becoming an increasingly attractive alternative for brands concerned about political instability, rising labor costs, or supply chain risks in China. 

Vietnam offers a skilled labor force, competitive production costs, modern factories, strong expertise in activewear and casualwear, well-established export logistics, and preferential trade benefits under the EVFTA, which significantly reduce tariffs for goods exported to the EU, making it a compelling option for brands ready to scale while maintaining quality standards.
