Leila wool is a hat made from the finest combination of 90 % merino wool and 10 % cashmere, which makes it super-soft. Leila is rib knitted at the bottom. Merino wool and cashmere are both higher quality of wools and known for the extreme softness, superior shine and great breathability. We recommend to wash this garment at 30 degrees using a gentle machine cycle and mild detergent soap (especially formulated for wool). To help keep your garment from pilling we recommend to wash it inside-out.
