Not too hot, not too cold, but just right!

outlast blogOne of the fibers used in Mrs. Crosby’s Train Case yarn is called “Outlast Viscose”.  The word Outlast is trademarked and we wanted to know more.  We know the yarn feels terrific but were curious about a fiber we had never heard of before.

It turns out to be a very interesting story.  Outlast technology enhances textiles by providing temperature regulation that manages heat and moisture.  It is a process that can be incorporated into fabrics and fibers that was first developed for NASA!

For those of us without a science background compare the Outlast technology to an ice cube in a drink.  As it melts, it can absorb heat while it cools the drink.  The Outlast process provides this benefit to the fibers.  It also has the capacity to absorb, store and release excess heat.  The claim is that any product containing Outlast technology “has the ability to continually regulate skin’s microclimate.  As the skin gets hot, the heat is absorbed, and as it cools, the heat is released.”  The intention, simply, is to keep you cool.

Outlast is not the same as wicking, which manages moisture by pulling it away from the skin.  Outlast is supposed to proactively manage heat while controlling the production of moisture.

While this may be more information than anyone needs in order to enjoy Mrs. Crosby’s yarn, it sure is pretty fun.  Plus, what a perfect yarn and technology for any garment – particularly that pair of socks for your favorite man.  You can tell him that the fiber has been “Tested in Space”.
