No more polypro for cold weather climbs.

I first tried the 150 Atlas on my recent winter expedition as a base layer under the Icebreaker GT 220 jacket/shirt. I was a little hesitant to change from polypro on such an important trip, and brought my regular base laters just in case- but after the first few climbs up the mountain I was really impressed and never looked back. I am 6'2 190lbs but used the large size to ensure a snug fit- which not only improves layering but is warmer and helps with muscle support during activity. I was told that merino wool would stretch but the Atlas top held its shape (mostly), even after weeks of constant wear, and then it returned to a snug fit after each hand wash. The wicking ability of this shirt is really amazing. Downside: I felt a little itchy at times, but this is a small price to pay for such major improvements in my base layer performance.
