Carhartt K122 is a versatile full-zip sweatshirt built for both work and everyday use. The fabric is a 10.5 oz (356 g/m²) midweight fleece in a cotton/polyester blend (50/50), providing good warmth without excessive weight. The full-length zip at the front makes the garment easy to put on and take off, and it works equally well as an outer layer on mild days or as a mid-layer under a jacket in cooler conditions.

The sweatshirt features a generous Loose Fit that allows freedom of movement. The adjustable three-piece hood with drawcord offers protection against the elements, while rib-knit cuffs and a hem reinforced with elastane retain their shape and keep out the cold.

At the front there are two hand warmer pockets and a full-length brass zip, with the Carhartt logo sewn onto the pocket. Triple-stitched main seams ensure the garment withstands heavy use over time.
