Delta is the high-visibility T-shirt for businesses where being seen is part of being professional. It is made for teams working in logistics, transport, warehouses, construction support, delivery, maintenance, events, outdoor service, and operational environments where visibility, movement, and responsibility matter every day.
High-visibility clothing does more than make people noticeable. It gives order to a busy place. It shows who belongs to the team, who carries responsibility, and who is there to keep the work moving. Delta gives that signal clearly while staying light, breathable, and practical for active working conditions.
Made from 100% bird’s eye polyester at 130 gsm, Delta uses breathable technical fabric designed for comfort during movement. The short-sleeved design includes two reflective strips around the body and one reflective strip on each sleeve, helping the wearer remain visible from different angles. The collar is made from the same fabric and finished with a covered seam for a cleaner feel. Delta is available in plain and colour-blocked options and includes the Roly WRK label on the outside.
Delta is certified in accordance with EN ISO 13688:2013/A1:2021 and EN ISO 20471:2013/A1:2016. Colour-blocked combinations 55221, 55223, 52221, and 23221 meet Class I standards, while colours 221 and 223 meet Class II standards. It is available in sizes S to 4XL, with measurements from S at 48 cm by 71 cm, M at 51 cm by 72 cm, L at 54 cm by 73 cm, XL at 58 cm by 75 cm, 2XL at 62 cm by 77 cm, 3XL at 66 cm by 79 cm, and 4XL at 70 cm by 81 cm. The model shown is 179 cm tall. Delta is machine washable at 30°C and designed for over 25 wash cycles.
With Sofiaga, Delta becomes more than a high-visibility T-shirt. It becomes part of a uniform system built around safety, clarity, responsibility, and trust. Because in operational work, visibility is not only about being seen. It is about being recognised as part of the team that knows what it is doing.
