It's taken me a month but I finally purchased a couple of wool jerseys and so far I am very happy. Both jerseys were purchased on eBay where I avoided the sometimes ridiculous cost of super fancy wool. The first is a short sleeved retro jersey by Sombrio which includes a shifty looking dirtbag with every purchase.
"Our fine clothing is made from the pubic hair of freaky man/sheep centaur things we find wandering around middle earth, I mean New Zealand"It's been too warm to really give them the proper going over. I did wear the long sleeve Icebreaker all last week where the temperature ranged form 45° to 70°. In the mornings I had to wear my vest to block the wind as that seems to be the only thing merino wool can't do. The wool regulates temperature extremely well. I was warm at 45° and warm, not roasting at 70°.
The 260 weight wool is not ideal at 70° but it's doable and I can't say that for a thicker synthetic. For additional versatility I got the short sleeved lighter weight Sombrio jersey. On warmer fall days I can wear it combined with my wool arm warmers if they're needed.
As a bike commuter this flexibility is priceless, (almost). This time of year I usually have to stuff my bag with additional jerseys and arm/knee warmers to combat the temperature fluctuation. With the wool at least I can leave the extra jersey and arm warmers at home.
The best part is, after a week of commuting in the same jersey it didn't smell... really. Merino wool has broken The Great Stink Cycle! This makes me, my co-workers and most importantly my wife very happy.
I am pretty pleased with merino wool and excited about adding it to my commuting arsenal.
he he... arse...
