The 'IrelandsEye Polo Neck Aran Sweater | Navy' is crafted from 100% Merino Wool. This polo neck showcases traditional Aran cable patterns and features natural flexibility. If the garment feels snug initially, the fibers will loosen with a gentle stretch. It is designed with a regular fit, but for a more relaxed and generous fit, consider sizing up. For care, hand wash in lukewarm water, do not bleach or tumble dry, dry flat, reshape while damp, and store folded in a cool, dry place.
