Lambswool is the highest quality sheep's wool. It is coming from the first shearing of a sheep (lamb) at the age around 7 months. This is the highest quality of sheep's wool on the market. It's gathered from a lamb's first shearing, meaning the fibres are smoother, stronger and hold more elasticity than any other wool. The fleece is 50mm or shorter. It is exceptionally soft, slippery, resilient, elastic, and has supreme spinning properties. The unique crimps in the individual strands generate air pockets that retain heat while repelling moisture, keeping you warm when you're cool, and cool when you're warm. Along with being a naturally insulating, breathable and hypoallergenic textile, it's beautifully soft. Doesn't get much better than that.
