85% Superwash Extra fine Merino (19.5 micron) 15% Nylon Yarn (4/16Nm) The extra fine merino wool makes this yarn luxuriously soft and bouncy for next to skin comfort. A little nylon is added for extra durability. The main factor determining the quality of merino wool is its softness which depends upon the fineness of the fibres. We use extra fine merino (19.5 microns) which is some of the finest commercially available. This results in a super soft yarn that feels gentle against the skin. One of our best sellers. This yarn is so versatile and can be used for any next to skin project (scarves, jumpers etc) as well as items where a little more durability is required such as socks and gloves.
