About 5 years ago I bought a grey Woolerina long sleeve t-shirt during a fair in Canberra. I wore the shirt all over Australia while we lived there, took it with me to Europe, used it as a base layer during a backpacking trip in the Northwest USA, and am proud to say I wore it while sleeping under the clear skies in the Kalahari desert in Botswana Africa last week when the temperature was 10 degrees C.
It's a great garment, and I'm very glad I made the investment.
