A sleek, modern windbreaker jacket from emerging streetwear label CHASANSUI, featuring a minimalist black shell with contrasting olive-green paneling on sleeves and side seams for subtle depth. Constructed from lightweight, water-resistant synthetic fabric with a high stand-up collar, full-length front zipper, and adjustable drawcords at hem for customizable fit. White piping accents along seam lines add clean graphic contrast, while the left chest displays a small embroidered 'BIVETLOCK' logo—a stylized wave motif with text—indicating a possible sub-line or collaborative identity. Two front zippered pockets ensure functionality, and elasticated cuffs enhance wind protection. Ideal for transitional weather, this piece blends utilitarian sportswear aesthetics with contemporary street style. Perfect for daily urban wear, layering in spring/fall, or casual outings where comfort and understated design are prioritized. The relaxed, slightly oversized silhouette offers versatility across body types, making it a unisex staple for modern minimalists seeking functional fashion.
