Down in this part of the world [ Australia and New Zealand ] an interesting new line of wool survival products are making inroads into the high end of the expedition and adventure environments. The technology involves the use of the extremely fine Merino sheep wool to make a range of undergarments and clothing claimed to easily outperform the synthetics and wool blends. I personally have not tried them but have read enough testimonials from respected folks to certainly put them on my list of must-haves. There are two New Zealand brands, Icebreaker, and Everwarm.<br>Everwarm can be seen at <br>http://www.everwarm.co.nz/Merino_html/Merino_html_products.htm<br><br>IceBreaker has the same technology, but their product range is aimed more at what I would call the Patagucci [ leisure ] market.<br><br>I would be interested to hear if the Merino products have reached the US.<br><br>Cheers, Peter Rattenbury.
