Fashion brand Strellson Sportwear has announced plans to expand its cooperation with boxers Vitali and Wladimir Klitschko. The brand will equip the twins with 450 pieces per training and fight phase, including t-shirts, training pants, jackets, vests and socks. The collection was developed in partnership with the brothers with Wladimir’s portion dominated by the color red and the slogan “Failure is not an option,” while Vitali’s features black and the words “Nothing is impossible.” For the first time, Strellson has also designed a cape and shorts for the match. Furthermore, the official appearance training gear carries a hidden message: The lyrics to Hells Bells by ACDC and Can’t Stop by The Red Hot Chili Peppers, songs that are always played when Wladimir and Vitali enter the ring, have been printed on the t-shirt interiors.
