This safety sweatshirt is specifically designed for outdoor workers, featuring a construction that combines **"high-visibility fluorescent fabric + high-brightness reflective strips + fleece lining"**:

**Main Fabric:** Features a color-block design with a fluorescent yellow upper section and a black lower section; the high-visibility fluorescent yellow ensures the garment is conspicuous and easily identifiable during the day.

**Reflective Design:** Incorporates 360-degree wraparound high-brightness reflective strips (located on the shoulders, chest, arms, and cuffs) that reflect light in low-light or nighttime conditions, thereby enhancing operational safety.

**Closure Design:** Features a 1/4-zip stand-up collar, allowing for easy donning and doffing as well as adjustable ventilation; the stand-up collar also provides wind protection and warmth.

**Functional Details:** Equipped with a zippered chest pocket and a kangaroo pocket—a dual-pocket configuration that offers convenient storage for tools and personal items; ribbed cuffs and hem provide wind resistance and thermal retention while ensuring a snug, comfortable fit.

**Interior Construction:** Features a fleece lining that effectively retains heat and locks in warmth, making it ideal for work environments with low temperatures during the autumn and winter seasons.
