Marlow Blue Ocean® Doublebraid is the latest addition to their eco-conscious, sustainable Blue Ocean® product range.
The Blue Ocean® range is manufactured from 100% recycled rPET polyester sourced entirely from waste plastic bottles.
Please note the current advisory from Marlow:
Due to current global supply and material consistency issues with some rPET raw material, Marlow have unfortunately had to take the decision to substitute the coloured yarns for regular polyester yarn meaning that the rPET yarn in this product now accounts for 75% of the product instead of 100%.
