Sockwool by Opal Rainforest With the rainforest collections the manufacturer Opal has created a design, which is widely accepted and considered as unique and innovative. Not for nothing we are about to deliver the fourth edition. Unlike to previous collections the patterns and colour-combinations were not designed on a sterile drawing table but were inspired by inhabitants of the tropical rainforst, like butterflies, birds or frogs. Through this the yarns make one experience pure vitality and the little bit wanderlust one always needs to look forward the next holiday and the time which is to come, to pack ones suitcases, filled which yarns by Opal, of course!
