Sports World are part of the Lonsdale london Group who bought the karrimor name when they went out of business there are several threads on the topic.. PRI now make the karrimor packs but Lonsdale seem to have gotten a load of the old bags from before PRI took over production and are selling them in their stores to get rid of them, the plymouth one has run out and dont seem to be getting more in so i would say if your store has them get them while you can!
