Made from a blend of 85% organic merino wool, 13% polyamide, and 2% elastane, these rib knit tights combine the natural benefits of the soft merino wool with a small amount of synthetic fibre for added durability and excellent elasticity. The merino wool fibres will naturally breathe against your child's skin and help regulate your child's temperature throughout the day. The merino wool fibres will also absorb moisture and help prevent odour to build during and between use. They have a comfortable and flexible fit, allowing your child to run, explore, and play without feeling restricted. They also have an elasticated waist, so they are easy to get on and off - and won't slide down.
