Hi Dana

You can order both the Antarctica and the Arctic tartan from Ros Jones on the Isle of Mull at http://www.celtictartans.com/our_own_tartans.htm
The web site also has description of what the colors stand for. It's a nice weight for a lighter kilt (it's a D.C. Dalgiesh weave), and it also makes a swell heavier shirt. My husband's worn his Antarctica tartan shirt south of the Antarctic circle several times.

Cheers,

Barb
