Icebreaker BodyFit 200 Mondo 1/4-Zip Top - Men's

First, I should say I own several comparable shirts from Pata_nia & Sm_rt Wo_ol. I'm 6'1" & 170 lbs and this one fit's me very well in a large (medium was tiny, not even close), better than the SW one which is a little short and large in the body for a large. I wanted to love it, however the deal-breaker for me is that it is the itchiest of the three by far. To be fair, the Pat. one is 20% polyester, but the SW one (which is 100% merino) is by far the softest of them all. Ended up returning this as I felt I wouldn't wear it when I have others which are more comfortable.

Perfect weight for fall temps. (40s-50s). Under a wind shell a great combination for hiking, maybe a little warm for running. Icebreaker merino is super soft. Doesn't hold odor. Wicks well and dries fast and doesn't feel clammy even when drenched in sweat. Cut is very athletic, as in skin tight, so if you like something looser, go with Smart Wool. It's stretchy though, so not uncomfortably tight. I just wouldn't wear it around town. A little too revealing for that. Slim is good work working out though. The collar height is nice, not so high that the zipper rubs under the chin. I like the raglan sleeves too (i.e. no seams, flat or not, on shoulders to chafe under pack straps). The zip could be maybe and inch or two deeper for more venting.

This is a gift to my husband and he loves it. The 200 weight is thicker so it is not torn easily and it is warmer.

I have this top in Camo and really like it a lot. The fit is great, close to the body without being too small looking or tight feeling, and yet allows great mobility during activities. I use mine for running, biking, hiking and it looks good enough to just wear around. The zipper is great for ventilation if you start to feel warm. Only thing is you really need to follow the care instructions to make it last and continue to look good.

I bought two of these shirts in winter 2008/2009. I loved them. I soon after bought Altitude crew shirts, superfine t-shirts, and leggings. I became a merino wool slut. Unfortunately, the durability on the Icebreaker products is terrible. Both of my BodyFit200 shirts have half a dozen very small random holes after just one ski season. We followed the instructions not to over-wash them and never put them in a dryer. This was our third Icebreaker product to do this (my wife's Nature Lite shirt and Altitude zip-top previously did this), while none of my other merino wool products have done this (DC, SmartWool, Ibex, ExOfficio). Icebreaker refused to replace them under any kind of warranty. Net-net: these things are awesome while they last, but at these premium prices, they should last a helluva lot longer.

Second favorite icebreaker shirt behind the oasis crew. Very versatile and the zipper provides good ventilation. I have had no problem with quality, have more than 10 shirts and only one have a small hole on the elbow. Icebreaker is expensive, but it does a great job managing moisture and controlling body odor.

Like my IceBreaker leg thermals this top is equally as excellent.

During a lengthy excursion in Banff, AB, Canada in conditions with wind-chill as low as -36° F I was kept warm at the skin protected by a fleece layer and a good Northern Face guide jacket.

In warmer conditions the product worked equally well during a full day of play in temps between 16° F and 28° F.

I found the product fit well, stretched and moved with my body as needed and was easy to put on and later remove.

Overall in the conditions described above I rate the product a 10 of 10.

I have used this top twice while backpacking. The first time was a day hike in about 60-65F weather. The breeze cut thorugh it and kept me just the right temp. When I stopped my back was a little wet from the backpack and sweating, but I was very comfortable while lounging and enjoying the scenery. The second trip it was 40-50F. This time I had a full 50 lb pack for a quick overnighter. While hiking it was perfect. The zip allowed me to control my temp and I never overheated, but felt comfortable. When making camp I was fine and when the wind kicked up added a MH Power Stretch and hat. I couldn't believe I was still warm. I needed nothing else. I am 6', 170#, 33 in waist, and the large is perfect. I have worn it in public on the way to hiking and was at first a little self conscious, but as I get older I don't give a rat's A$$ anymore. My wife says it just shows that I am fit and will even be seen with me, so it must be fine. I also bought a 260 and assorted leggings based on my great experience with the 200. It hasn't been cold enough to wear them out, although I did wear the lightweight leggings for PJs and I was very warm. I'm sold on icebreaker.

This thing does exactly what it's supposed to... I just wore it every day on a 5 day backpacking trip and it kept me dry on the way up, and warm on the way down and at night. Its comfortable and the zip top is key for releasing heat on a tough climb. At night or on the slopes it's great as a base layer. Can't say enough about this thing... After 5 days in the wilderness, I come home and my wife says it smells clean. Pretty amazing!

Been great for snowboarding, rock-climbing, walking around being a tourist!
