Icebreaker GT150 Velocity 1/4-Zip Shirt - Long-Sleeve - Men's - 2009 BCS

Great top to wear all day if you expect temps ranging from 60 to 85+. I have the all black version and it was just fine in direct sunlight at 87 degrees. The important bits - it breathes very well, particularly in the waffled sweat zones and keeps you from feeling hot and damp. With a light breeze, it cools fantastically. At the cooler end of the scale, I had expected the fantastic breathing ability to work against it, but, strangely, it didn't - it stays comfortably warm. If you're going to be doing more than a casual walk, I would expect that this top would be comfortable on its own at even lower temps.

Fit and finish - buy your normal size if you want it to be more form-fitting. Size up if you want it a little more casual fit (I'm 6', 205lbs - XXL is a casual, not sloppy, fit for me). Fabric is soft, very slightly scaly, but on the balance is far more comfy than cotton. Logos and zipper are reflective.

This is the usal icebreaker quality pullover in a super light fine wool. Athletic fit - very breathable- and feels as light as a long sleeve tee shirt - good to about 50 degrees with short sleeve baselayer.

Having made the wool migration several years ago, I've always wanted more breathability, and now I have it. These tops have body mapping fabric that is more porous in the "sweat zones". Used skiing and winter running and been very impressed.

The GT 150 Velocity 1/4-Zip LS shirt is now the only 3 season (west coast) cycling shirt I will use now and in the future. I'm 6'1", 165 lbs., 41" chest, 34" sleeve and the large fits me perfectly. All the positive reviews I have read are consonant with my experience. Finally, I can't say enough about Backcountry's quality service.

This L/S baselayer is just what I was looking for. Lightweight, breathable, doesn't retain odor. Great fit and love the looks. They go great with my IB 150 bottoms for snow skiing and I even use them in TX when playing winter golf where the highs might be near 55/60. I'm 5'10" 170, 42" chest and went with an L. Can usually wear M, but I think L was best, non-binding and long enough sleeves.

This shirt is amazing! I wore it for 6 days before I had to wash it. I went biking and running in it every day in 70 degree weather. It wicked away the moisture and protected my skin against the sun. Best of all, the shirt didn’t smell once I was done. Icebreaker GT is my new favorite active wear.
