Artwrote a review of Icebreaker 200 Oasis LS Crew Top - Men's on November 17, 2018
Familiarity: I've used it several times
Fit: True to size
I was given this product from Backcountry, but this review is my personal opinion. I want the reader to be aware, as part of the testing program Backcountry wants honest reviews, the good, the bad, and the ugly. With that being said, I've worn multiple brands of base layers over the years and the Icebreaker Men's BodyFit 200 Oasis is now my go to. I have the 1/2 zip version of the top.
I'll start with sizing. I am 5'11", 165 lbs., waist 32", chest 40". I tested a size medium top and medium bottom. The fit for my build was spot on to the sizing chart. I have included a photo so you can see the fit on my frame. The fit of the top around the waist and chest are not compression tight to the body like Under Armour but it is a tailored, athletic fit. If you want the top layer to be tight against your entire body like Under Armour you may want to order a size smaller. Personally I like the fit.
Transitioning to performance. This product hits all cylinders. I've had the Icebreaker Oasis 200 for about a month now and have worn it about ten times. I used it running, mountain biking, hiking, and working outside, still lacking the snow coverage to test it while skiing.
I'll start with the good. You know you are going to sweat during aerobic activities. The Oasis transfers the sweat away from your body well and dries quickly. A huge bonus is that compared to my other synthetic base layers this one shines in the smell department. Usually after a day of use my other base layers ripen. I was amazed that after a run I let it hang dry without washing and it smelled fine the next day, and the next, and the next. To me this a huge bonus for multi-day trips when space and weight are key. The warmth to weight ratio is great. I have wet suits lined with merino wool and the Icebreaker Men's BodyFit 200 Oasis reinforces why. As I previously stated you know you are going to sweat during aerobic activity, this base layer seems to do a better job keeping you warm while it dries. Another bonus is the 1/2 zip looks nice enough to wear as is when you grab a bite after playing.
Regarding durability, the jury is still out on this. I have only had the Oasis 200 for about a month; however, so far there are no issues. The quality looks good for its intended use. I have a front-loading washing machine and I hang dry so I have not tested it against an agitator or heat.
The ugly: it's not inexpensive; however, based on its performance it's worth the cost.
