'nother pair of sox !

My most recent pair.  

Eyelets on the leg portion both front and back.

This yarn has an interesting component. 

It's called Outlast.  

I've pulled a couple of explanations off the web for ya.

Outlast^® technology, 

originally developed for NASA, 

utilizes phase change materials (PCM) that absorb, 

store and release heat for optimal thermal comfort.  

Outlast^® technology is comparable to ice in a drink; 

as it changes from solid to liquid, 

it absorbs heat and cools the drink, 

keeping that drink at the desired temperature for longer.

 Outlast^® phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell. 

We call microencapsulated phase change materials Thermocules™.

This encapsulation process makes the Thermocules™ exceptionally durable for many applications. 

These Thermocules™ can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat.  

This gives any product 

containing Outlast^® technology the ability to continually regulate skin’s microclimate. 

As the skin gets hot, the heat is absorbed, 

and as it cools, that heat is released.

Outlast^® technology is not wicking technology, 

which manages moisture by reacting to your sweat and pulling it away from the skin. 

Outlast^® technology will proactively manage heat while controlling the production of moisture before it begins. 

The Loopy Ewe has this to say:

"This sock weight yarn is made from 

superwash Merino, nylon and Outlast

Outlast, a fiber technology that interacts with

the body's microclimate to moderate temporature

to help from being too hot or too cold.

It's yarn with a built-in climate control !"

Anyhoo, they feel great on my feet and I love the colors.

What more could a gal ask for?
