Rukka Outlast Underpants (long)

OUTLAST knitwear directly on the skin.
OUTLAST temperature control is able to compensate for body temperature fluctuations by absorbing, storing and releasing large amounts of heat. It makes sure

that the temperature is not too hot for the wearer ...
not too cold .... but is just right, and that over a wide range of outside temperature and degree of activity.
The OUTLAST underwear is very comfortable to wear
