A new Polartec fabric that minimises microfibre shedding whilst keeping you warm and comfortable. Sheds five times fewer than other Polartec fabrics. 100% recyclable and largely made of recycled materials. Works like bubble wrap, containing the fibres in pockets to maintain heat. Polartec Powerair aims to address issues with microfibres and plastics causing pollution. Available in mid-weight and lightweight versions. The lightweight version, the Houdini Monoair, doesn’t contain elastic and so is less stretchy.
