If you want to travel light in cool weather this is almost magic. You can go 2 to 3 more day without washing than any shirt. Amazing body warmth management: warm when you need it but cool enough when you don't. This was the most important item a 10 day Scotland in April with one small backpack 17x12x8.
I wore it and washed it 2 times. Please look at the picture and tell me that this is okay. Absolutely dissapointed. My REI merinos never developed such holes as Icebreaker did. This is my first and last Icebreaker purchase, considering the high price, I will no longer take the risks.
Just arrived! The Icebreaker Oasis top and bottom are great. Perfect fit, high quality and keeps the cold at bay. As a ski patroller, I’m out all day and Icebreaker keeps me comfortable. Tip - order you normal clothing size (seems obvious) and you will love the perfect fit!
The fabric feels amazingly soft. It was very form fitting and I was excited that it was worth paying the extra for until I realized every time I reached up the air it completely rose up to my belly button. It felt like it had already been shrunk in the dryer or something. The shirt was tight and form fitting in most places but down by my waist it wasn’t long enough or snug enough to stay in place. Someone else had a similar complaint. I buy arcteryx gear because they fit so well even though they’re expensive. But I’ve learned not to settle. I got this on a closeout and still will be returning.
Getting rid of all cotton shirts and switching to merino from the synthetic garments. Can get more wear without the synthetic stink, and it dries relatively quickly. Great travel shirt.
I've slowly been replacing most of my t-shirts, base and mid layers with wool. this a great addition love Icebreaker and all their products. Fits well and super comfortable.
The shirts are too short I am not able to tuck them into my pants.
I have purchased and worn Icebreaker for 20 years and it never disappoints!
