Ensuring the safety of pharmaceutical workers and the integrity of products requires a sterile environment. We have developed oversleeves for pharmaceutical factory workers, which deal with these challenging conditions. Thus, this garment is fabricated from high-grade, breathable non-woven fabric that does not allow contaminant passage and is comfortable for extended usage. These oversleeves also come with elasticized cuffs that fit snugly over garments, allowing concentration on work without having to stress over the danger of contamination. These oversleeves will find use in cleanrooms, laboratories, and production lines – they are indispensable to any safety protocols in pharmaceuticals.
