One Shirt for so Many Conditions
[This review was collected as part of a promotion.] Icebreaker US gave me this free product to try and I enjoyed wearing it while exploring Telluride on the mountain bike during leaf peeping season. At the start of the ride at the base it was on the warmer side and the Oasis 200 did a great job of moisture management and keeping me comfortable during my nearly 90 minute climb. Cresting at around 11,200 feet it was much cooler and quite windy but the Oasis 200 kept me comfortable and warm especially at the start of the descent. The fabric dries incredibly fast, and was basically dry by the time I came off the descent, which still had some aerobic efforts in it. Like other reviewers I found the shirt to be a little on the shorter side, but for riding I appreciated the shorter length as it really layered well with my hydration pack and shorts. I’m 5’10 and around 170 lbs and the size large is perfect for me. Could have easily sized down to a medium though for a more compression fit.

Love the fit and softness
These guys make great merino. The fit and softness are top notch. I love wearing this as a base layer in the outdoors. I recently took it on an Alaska moose hunt where we saw rain every day for two weeks straight, in fact, we only saw the sun twice in that time period. Even after getting wet, it stays warm and doesn't stink.

Exactly what I need!
[This review was collected as part of a promotion.] 200 weight is perfect for a winter base garment! It fits true to size with the sleeves a bit long, which I like. The neck fit is not too tight and the body length stays tucked in, even during repeated moves from standing to crouch.

Good product, but small
It is a very comfortable fabric, and so far durable over the first 3 months. It keeps warmth well, and does a great job of not developing an odor. I use it to work out in the morning, and while I don't get real sweaty, I can easily use it over a month before I even consider washing it. The one downside is the size. I'm 6'1", 190 lbs with long arms. I got a large, and the sleeve length is adequate, but is very short on the torso. Other than that, would recommend.

Wanted to love it!
[This review was collected as part of a promotion.] I wear Icebreaker boxer briefs everyday so I was really hopeful this would be the last set of long thermals I'd ever have to buy. Unfortunately I found the fabric to be too scratchy and uncomfortable on my skin. They look like quality pieces, just not for me.
