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).
