MERINO and 'TRADITIONAL' WOOL
Compared to traditional wool, fine merino fibre is a fraction of the diameter, which is one of the reasons why wearwoolf doesn't itch. The surface of all wool has microscopic scales, but on fine Merino these are much less prominent, and this makes it much softer to the touch. wearwoolf Merino feels like quality cotton.

MERINO and SYNTHETICS
Synthetic fibres such as polypropylene or polyester have a much simpler structure. They are made from melting, extruding and setting a petrochemical-based product, similar to plastic. The fibres can't breathe, absorb or release moisture. When knitted into fabric, they are limited to one-way moisture movement, with limited breathability, and this creates a 'chill' zone against the skin where moisture sits on the inside edge of the fabric. wearwoolf Merino has the ability to absorb and release moisture, to cool or warm the body, thus regulating temperature. You'll warm up quickly but not overheat due to the exceptional breathability of the fabric.

One Merino sheep grows enough wool in a year to make wearwoolfs for about a dozen kids. With over 9,000 follicles in just a square centimetre of skin, each of their fleeces produces more than 100 million fibres! If you joined them all from end to end, just 5 Merinos would produce enough fibre to circumnavigate the world.

Merino has always been much finer than other wool, and in recent years woolgrowers have been able to improve the quality of Merino fleece more than ever before. Compared to synthetics, Merino is way more technically complex.  

Tiny overlapping scales case the fibre. They're hydrophobic (water resistant), like tiles on a roof. Inside however the fibre is highly absorbent. 

Merino is the most hydrophillic of all fibres - it can absorb and release 10 times more moisture than synthetics! Each fibre can absorb up to a third of its own weight in moisture without feeling clammy or wet to touch. Your wearwoolf releases moisture into the atmosphere, and that keeps you feeling warm and dry.

Wool fibre has evolved over 25,000 years to create a uniquely complex structure of interlocking protein molecules, surrounded by electrically charged lysine side chains. Through a natural process called 'hydrogen bonding', these side chains electrically attract water vapour molecules. The wool fibres actually pull the moisture vapour away from the skin. As so often with nature, it's incredibly complicated but extremely effective - and very hard to imitate. Because its layers of molecules are so much more complex than any synthetic, wool draws moisture vapour away from the skin faster.
