Gresvig, the largest buying group in Norwegian sports retailing with the G-Sport, G-Max and Intersport banners, has lost yet another weighty outdoor supplier: Bergans decided not to renew its central purchasing agreement with its largest retail customer and will start dealing instead with XXL, another Norwegian retailer that is shaking up the market with large formats and cheap prices.

Norrøna already opted to sever ties with Gresvig two years ago, and Helly Hansen went the same way last year. Bergans told Dagens Næringsliv, a Norwegian newspaper, that the decision had been necessitated by disagreements with Gresvig on terms and conditions, as well as the opportunities offered by XXL's entry into Sweden last year.

The breakup with Bergans leaves Gresvig without three of the best-selling outerwear brands in Norway. Rolf Gullestad, the chief executive of Gresvig, was quoted as saying that the buying group had purchased Bergans products worth more than 150 million Norwegian kroner (€19.4m-$26.7m) this year.

This makes up a sizeable chunk of Bergans' sales in Norway, which reached NOK 520 million (€67.3m-$92.5m) on a turnover of NOK 645 million (€83.4m-$114.8m) last year. The brand will continue to deliver to Gresvig next year and start working with XXL from the following year.
