I started hiking about a year ago in the Los Angeles area and have recently received a promotion / transfer to Northwest Indian, which will go into effect in late December of this year. Moving from a desert region to an area that I am guaranteed to see snow and cold temperatures, I have become increasingly concerned about my base layer for the winter. After reading these forums it seems that most lean towards merino wool for their base layer. Unfortunately, I’m allergic to wool; have been since I was a kid. I attempted using smartwool socks this year, hoping that there would be no adverse effects, and broke out in a rash all over my ankles and upper feet. I’ve tried the socks two times since then with the same results. I switched to a synthetic blend socks and have had no issues with rashes since the switch. I’ve never had issues with wearing a sweater in the winter but I’ve also never worn wool for any athletic type of activity. I even wore wool socks through my first years in the Navy and never witnessed any problems. However, during those years I always switched to cotton socks for PT. I’m at a loss as to why a blend would cause such an adverse reaction when other wool products have not. Either way, I’m not going to put money into buying wool items if there is any chance of a reaction.
I’ll be traveling between NWI and LA between every 1-3 months and with family in NJ, my hiking conditions will vary from desert, to wet and damp woods, to lake-effect snow. My concern right now is primarily cold weather hiking. To top off my clothing issues, I’m 6’2”, 240lbs so unless the company makes XXL clothing, they’re not even an option for me. Can anyone point me in the direction of reputable companies that have non-wool based options? From what I’ve read, I’m guessing that GoLite and Patagonia may be good starting points.
