When you say allergic to wool?  Does that apply to all wools?  I assume yes.  But, we know what assume can do.

Arc'teryx, Patagonia (as already mentioned) and REI all have some non-wool versions as well.  

Have you tried some Google searches (Bing or other searches)?  There are a few sites that do reviews of gear and apparel.  And, I noticed on the one site I use quite a bit that there are a good number of non-wool apparel items.  Socks might be a bit tougher.  That same site showed a couple of non-wool options (Wigwam and Wrightsock).
