Nua is a blend of merino, yak, and linen. Each of these fibres contributes something special to create an amazing yarn blend.

Merino provides a soft, squishy, and versatile base. Yak adds a unique silkiness to the yarn that your fingers will simply love. Finally, linen adds strength and durability.
Nua is non-superwash, which creates a lighter yarn with a bit more bounce, making blocking easier and helping projects (especially garments) to hold their shape nicely.
 
Sport weight yarns are less common in Europe, but I think it is the perfect weight; it is light enough to do fine colour work and create lighter sweaters, but still knits up quickly enough that big projects don’t take too long.
