"The Merino 200 weight has held up great. I’ve been wearing it multiple days every week for months at work and no runs or holes like the Merino 150 weight Tech lite gets. It’s not to heavy to wear in the summer even when you are working hard. . I will certainly order more and highly recommend it"

"Love these shirts, I own short and long sleeve ones. Very soft and warm, can wear for days without washing. Only thing is they run small so I had to go up a size"

"My partner lives in icebreaker tees and hoodies. Great quality. The slim fit fits him like a glove. I love options of different colors beyond blue/grey/black."

"My go-to Tees. Comfortable, wonderful materials and construction . Have been a customer for many years."

"Would be a great product, except for the care tag, which is printed on a hard and sharp nylon (?). It digs into the skin and causes irritation. It can't be fully cut out—my best efforts don't work."
— Ben (1/5)
"What an awful first experience after a big hype-up about Icebreaker. Fabric seems good quality but cuts are not aligned with size guide (which is a written contract between vendor and customer and constitute false advertising when not reflective of the product). have contacted multiple times, they can't find the order, they never made me an account (wth) which makes it even harder to do the return, they say they've authorized the return but then the label never shows up. I finally had to create dispute in my card and publicly list the ACTUAL dollar figure details on social media publicly just to get a response. UNACCEPTABLE. To spend Neiman Marcus $ and be treated worse than at a dollar store, they should be ashamed of themselves. And btw fix the cuts of your products to fit actual humans."
