Dubbed the YZY KNIT RNR BT, the model iterates on its predecessor without straying far from the original concept. Its lower half is actually part-identical, the knitted, yellow-colored exterior simply improved with a ripple sole. The elastic collar, which has been given new 'WATERPROOF' and 'DESIGNED IN USA' text, then serves as a visual break between the aforementioned and the collar. Fastened by way of velcro, the latter resembles the quilting of the YZY NSLTD BT though a bit lighter and slightly less padded.
