this may be of interest in relation to this discussion- macpac has some new deals going for those of us that live in merino( or those that have been put off by some high prices.)
http://macpac.com.au/I'm a big believer in merino- I pretty much wear it everyday- to work, on the bike, on a run.. it just works for me. Anti odor, fire resistant, naturally renewable, bio-degradable, has the ability to regulate temperature (sorption) and dry feel against skin even when it has absorbed 30% of it's own weight in moisture. In all but the wettest of conditions I'll wear merino over a synthetic everytime. (but will choose a sportswool/ interwool as second choice- blend of merino and polyester)
the link will take you the Macpac website- click on the link in the banner to see New NZ made merino, in a wide range of weights (we will soon have 130gsm, 150gsm, 190 gsm, 230 gsm, 280 gsm, 390 gsm) and MWC members will have access to pricing that is pretty hard to beat for a quality product. (more styles added over next few weeks )
