When you'll be climbing, running, hiking, or traveling for weeks without doing laundry, the Patagonia Men's Merino 1 Silkweight T-Shirt will keep you comfortable and stink-free. The merino wool in this short-sleeve shirt naturally breathes and resists odors from building up over days of wear, and the soft fabric regulates your body temperature if you're too hot or too cold. Polyester was added to this baselayer for durability, dry times, and moisture transfer that will keep you dry during your entire hike in the hot sun.

  • Blending merino wool with polyester results in a breathable shirt that naturally controls odor, that's durable, and that wicks moisture
  • Slim fit allows easy layering if you want a windbreaker when you top out on multipitch routes
  • Side seams prevent bulking and uncomfortable rubbing and chafing
  • Set-in sleeves give you a natural freedom of movement

awesome shirt

  • Familiarity: I've used it several times
  • Fit: True to size

    Size Purchased: Medium

i decided to go with a wool shirt because when out on road trips, washing can be inconvenient. I've worn this shirt for days straight and can't believe there is no smell! The fabric is soft, yet pretty durable. I've been out bouldering on sandstone and despite a few sketchy mantles, there is no visible damage to the shirt. 5'9 135ish and went with the M and found it fits a bit tighter than Icebreaker's wool shirts, but not skin tight (exactly what I was looking for).

Sure, it's expensive, but it's the best t-shirt I've ever bought. On a 7 day fishing trip in the backcountry, this is the only t-shirt I would bring. And no odor whatsoever---this smells exactly the same after several days of non-stop hiking.
