Professional cold weather vests, such as those from RAG Tailors, are designed with superior thermal insulation, more resistant materials and reinforced seams to withstand intensive use in demanding environments. They have technical features such as functional pockets, reflective elements and are often compatible with other workwear items. Casual vests, on the other hand, prioritize aesthetics, with more varied designs and colors, but generally offer less thermal protection. Professional models also comply with specific safety and thermal protection standards, essential for low-temperature work environments.
