As a photographer, much of my work is location-based. In the winter months, this means long 4 - 6 hour assignments in weather 35° and below.
I first tried the Jockey Smart Thermals in 2011, and was amazed at the way the garment responded to temperature changes. I felt comfortable in 30° the same as 65° when I went indoors the same day.
The orignal design used Outlast Viscose and worked pretty well, but Jockey improved this design for 2012 using Viloft fibers -- an incredible insulator that uses your own body heat to create a warming layer.
The new tops have thumbholes in the sleeves making it more functional and easier to wear under a long sleeve shirt. Additionally, the fit of the bottoms is greatly improved and retains its shape even after a long 9-hour day!
Thanks, Jockey, for bringing these back and making your best even better!
