This is my 4th icebreaker shirt and it certainly hasn't let me down. A comfy slim but not quite spandex fit that goes well under everything from dress shirts to ski parkas.…

I love my woolens. I've got quite a lot of Icebreaker clothing and wear them all winter long. I got myself a couple of Icebreaker Apollo short sleave shirts a while back and…

It was my first Icebreaker garment. They advertise on the odor free characteristic of merino wool, but I wanted to know by myself. I wore it for 2 weeks day and night... and b…

One pair of socks converted me to the merino wool world. These pushed me over the edge, keeps everything cool and dry when out running in a pair of workout pants.…

These are very comfortable, light, and soft. However with alot of movement, they will tend to ride up some, slightly annoying but still love them.…

I'm 6'3" 180lbs 32" waist with long arms and the large fits me great. It isn't ridiculously skin tight on my stick figure, but form fitting enough that it layers perfectly un…

Its true what they say. This is my first Merino wool item, and it does cool me down when im hot, and warm me up when im cold. The quality of this product for something so thin…

I have quite a few icebreakers, but this one does not top the list. It isn't as soft as the others, and I prefer the ones that zip down lower. It's an icebreaker, so it's good…

This shirt is ok, but I prefer the the higher weight shirts. Plus, the zip on this is far less functional than the 3/4 zips available on some of their other products.…

Really like the feel of it, thin, tight to the body. Put it through the stink test - wore for most of 3 days, slept in it for 2 nights. Didn't exactly smell like a rose gard…

It was hard to believe while I was wearing this shirt that a fabric that you can see through can be wind resistant and as warm as it was. I was out running in the mid 50's an…

I bought shirt for running and it's kept me warm down to about 35 degrees. I get cold easy, so your mileage may vary. I run 30-35 miles a week mostly on the pavement. This is…

I love merino wool, and this has all the great advantages that merino offers, in a nice winter-base-layer weight top. Maybe it's just me not matching the proportions of the la…

A lot of friends would probably stare in disbelief if I told them my lightest, most breatheable pair of boxers were wool. Having just weighed everything to pack for my vacatio…

These are my preferred baselayer for warm weather performance activities. The fit is a bit tight compared to other manufacturers, so consider ordering a size up.…

If you like the classic fit then this is an awesome sweater. However be forewarned, it hangs a little boxier than some of the new icebreaker jams. And it runs a little looser…
