  • Good base layer choice
    Reviewed by Kenny A from Brooklyn, NY on Saturday, March 15, 2014
    Be happy Sierra scooped up these light weight merino tops from a reputable company. The quality control is excellent and the fit is true to size. Soft, itch free and warm enough for extended outdoor activity under a good shirt or sweater or by itself around the house. A great purchase. And merino has long term wearablity going for it. You needn't wash after every wear but when you do use a good wool wash product like the Nik-Wax product also sold at Sierra. Follow the instructions and these will last quite a while.
  • Lightweight comfortable wool
    Reviewed by aud the shopper from Lagunitas, CA on Tuesday, March 4, 2014
    I bought this for my husband.he was surprised it was wool because it was so soft. I know it runs a bit small because I have one too so I got one size bigger.

  • very lightweight, warmer than you'd expect!

    I really like this top. It has instantly replaced the synthetic tops I had been using (happily) for years. Machine wash, hang dry. In a pinch you can machine dry low heat if you remove promptly. It doesn't get stinky like the synthetics. I am a cyclist, and I can easily use this for several rides without washing. When I layer with this and other merino wool tops, the feeling I get when out riding in the cold is as if I have grown fur. I feel warm while still knowing that its cold, and when I get hot I am still comfortable and can hardly tell I'm sweating.
  • Great undershirt!
    Reviewed by Jessica from Richmond VA on Tuesday, January 7, 2014
    It really does not stink after repeated wearings. It is a good underlayer for cold weather outside, but also feels good indoors. Not itchy at all. The only complaint is really long sleeves, but I have learned to fold them up before I put on my dress shirt.

About Icebreaker

Crafted using only the finest merino wool grown in New Zealand’s Southern Alps, Icebreaker clothing is known around the globe for its incredible comfort and performance. Unlike synthetic fabrics developed in a lab, Icebreaker merino wool is grown, cultivated and field-tested in the mountains. Designed to offer exceptional comfort during a range of outdoor sports, Icebreaker underwear and apparel naturally resists odors, regulates body temperature, wicks moisture and dries quickly. Superfine New Zealand merino wool is also much softer than traditional sheep’s wool, which means no itch. Icebreaker socks, long underwear and base layers also come in a selection of weights to keep you warm without overheating. Ready to join the merino revolution?
