The collaboration features the iconic Needles tracksuit, the brand's most recognizable item and a testament to its unique style, in a special black and red colorway. The black track pants and jackets are adorned with red stripes, the signature butterfly motif, and a special One Block Down branded tag. Made from premium materials, the track pants and jackets offer a straight, regular fit. The collaboration also includes a black and yellow Mohair Cardigan, sporting a regular fit with two distinct patterns: a diamond checkered pattern on the front and a classic checkered pattern on the back.
