Private-equity firm Altor has remained coy on reports that it plans to put outdoor clothing brand Helly Hansen up for sale this week.

VF Corp, Jarden Corp, PPR and Columbia Sportswear have all expressed some kind of interest in the brand, Reuters reported, adding that the information memorandum is set to go out in a "few days".

Altor confirmed to just-style in December that it would be seeking more than NOK2bn for the brand. Swedish daily DN also reported in December that potential suitors could include big private-equity firms like Blackstone or the Carlyle Group.

Altor sold Helly Hansen Pro, a subsidiary focusing  on survival suits, boat canopies and textile-based products for agriculture, industry and health sectors, to Montagu Private Equity in December 2010.

An Altor spokesperson declined to comment on the "rumours".
