Icebreaker merino stuff

I'm not the sort of person who gets addicted to things, but I am a little obsessed with Icebreaker merino wool clothes these days. I'm trying to remember what got me started... I think I needed a warm layer for Eastern Sierra trips, and I picked up a coral pink long sleeve crew-cut 260. Icebreaker gear is rated by the weight of the wool per square ... foot? I think it's foot, but you can check the website (www.icebreaker.com) to confirm. So far I have:
* the original 260 long sleeve crew
* a 200 short sleeve crew -- more about this one in a bit...
* a black 200 long sleeve zip neck ("Mako")
* a black 190 tank top
* a dark gray 190 tee with a cool as all hell print of a wave on it
* a light brown 190 vee-neck tee -- just bought this one, we'll see how I like it
Merino is simply superior to cotton! I have enough of these at this point that I probably don't need to wear any of my cotton t-shirts most of the time, and I just don't. Merino doesn't smell, so you can wear it many days before you need to wash it, it doesn't need ironing, it's washed in cold water, which is more environmentally correct, and it's more comfortable.
These are expensive clothes, but once I knew I was hooked, I started buying them heavily discounted at sierratradingpost.com, which is outstanding. Real story: I wore the 200 short sleeve, which was powder blue when I bought it, nonstop throughout the J/24 South European championship. Because you can only wash wool in cold water, it developed some serious pit-stains (foredeck on a J/24 is no laughing matter!). I didn't want to retire the shirt, but I couldn't very well wear it like that, so I dyed it! I picked up some midnight blue dye, soaked it for an hour, rinsed it in cold water, washed it and wore it on my trip to Bryce Canyon this past weekend. The color is definitely fast, and I didn't have any skin reactions to the dye. Bottom line, this icebreaker stuff is the shit!
