So, I have been using this shirt for about a week (I have two and have used & laundered both), but haven't truly put it through the paces until this morning. I did the Crossfit workout "Murph", which lasted just under an hour and let me experience the pro's and con's of the Breathe 90 material.

My recurring thought is that the material is fairly analogous to merino, but lighter. The lightness of the shirt can't be overstated. It's a "barely there" material that feels great and is really smooth. Similar to merino, it breathes well until the point of saturation, then simply "holds" moisture and becomes heavy/ceases to breathe. In fact, it became so saturated this morning that I removed the shirt until the workout was over due to the "heaviness" of the garment.

As to fit, I'm 6'5" and 200lbs and the shirt fits perfectly, slim but not formfitting. I especially like the little bit of extra length in back for when I'm riding my bike.

For me, nothing on the market can beat Patagonia's Capilene 1 material for wicking performance. I have used them in the heat and humidity of GA summers and they continually perform like a champ. The only downside is in the cost of a capilene garment. That is where the Stoic Breathe shirt kills it - if you find it on sale/SAC, it's a deal you can't pass up.

So, for the TLDR'ers out there:
PROs - extremely light, great fit, price is right, works well for many different applications
CONs - reaches sweat saturation fairly quickly (YMMV)

Good job Stoic!

So i lusted for this jacket for quite a while. I wanted the Arc'teryx Atom LT but the price was too much - and I went w/ the Thermawrap BC after getting a deal. Plus, the orange is an awesome color and looks even better in person. I agree w/ the below reviewers on two main points: 1) the fit is not as advertised and 2) the stretchy material at the sleeves and sides degrades fairly quickly. I ended up sending this back and going with the Atom LT, as I should have done in the first place.

For reference, I am a lean 6'5", 190 lbs, and the Atom LT fits like a second skin.

So I am currently using the 12 in version to keep my pants out of my bike chain. Just one of the many daily uses I get outta this piece of gear. Keep it on you at all times, and you will continue to find uses for it. Good, solid stuff.

Ideally, this strap would have a TINY bit more elasticity, but I'm guessing that would compromise it's strength, which is substantial. So that's why only 4 stars, but at this price w/ so many uses, you shouldn't hesitate to purchase.

Three reasons this garment is worth the price:
1. No stink - you could wear this for a few weeks and never know it didn't come right out of the laundry.
2. The fit - nice and tight, very performance oriented cut. It looks great under a button down and all by itself. You get so much value out of this shirt because you can wear it with anything, rock it just with jeans, or lounge around in it at home. Plus, since you don't have to wait for it to make it out of the hamper, you get that much more wear out of it. Hands-down a terrific value.
3. The length - nice and long, even on me (I'm 6'5"). Long enough that I can tuck it in and it will stay put. Also, when I wear the shirt by itself, I don't have to worry about it coming up too short.

It easy to see why these have almost sold out. One last thought - even though it's a thin, fine grade of wool, it's very warm and will keep you toasty even by itself.

The only reason why I do not give 5 stars is becuase my shirt was mis-sewn - the seams are not symmetrical and it bugs the hell out of me. It just wears funny, plus it doesn't look as nice.

Great job Icebreaker!

Power Stretch is a great material and this shirt uses it well. Ideal uses for this sweater are coming out of the gym, you've been sweating, it's cold and you're going for a run. This fleece will wick that sweat away plus keep you warm and toasty. A major factor that keeps me from loving it though is the fit. Cloudveil stuff just fits funky - this top is too short for taller guys, even though it fits me perfectly in the body. Other items from Cloudveil are too big yet too short for me. So if you are a thin guy shorter than 6' you will fit this.

I spent a few months tracking down this jacket back in '06 and it was more than worth it. At around $175, you are getting a steal. Everything that made the Gamma MX famous is done better in this softshell. The fit is perfect for larger folks - I'm 6'5" with a wiry build and this trim, tailored piece fits me like a glove (size L). Very warm, enough to throw on over a cotton t and not feel the cold down to about 40-50 degrees. Throw a fleece under it, like the Delta AR zip and you won't ever feel cold. Blocks 90% of the wind out there. Super durable - you can climb and snowboard and bike in it, and I have yet to see it look like anything but new. Plus it's super stretchy, so you never feel constricted. Put it in the wash when it gets stinky and you are good to go. Westcomb is a badass compnay - all their gear is designed and manufactured in Canada and the quality shows. This is as core as it gets - buy with confidence!

Use this fleece for what it was designed for and you will never need another. It's worked it's way to the top of my gear pile for 3 simple reasons:
1. Weight - 11.7 oz. On your body, unnoticeable.
2. Warmth - By itself, wonderful is mild weather or around the house. Under a shell, all you need to stay warm and keep moving.
3. Breathability - Somehow the folks at Arc'teryx have designed the grid fleece pattern in a way that keeps you warm but never sweaty/clammy.

I had a cotton t and this fleece on when I got stuck 4-wheeling off of Jack's Cabin cutoff in CO during August. I had to hike out as the sun was going down, and from the start to finish, this fleece kept my temperature perfectly regulated. I truly didn't need another piece of gear; it kept me warm and yet cool because it breathes so well. What makes it killer is that it looks great for casual wear too! Don't think - just buy.

A 4 star piece, because nothing can ever compare to the latest and greatest fabric in my life, merino wool. 4 stars becuase it's better to sweat in than cotton (but not better than Cap 1), feels really nice and comfy, and even my wife just HAD to know what "beater" meant. Thanks for including the explanation card BC!

Flat-out these are the best workout shirts that exist. They breathe and wick better than anything I have ever tried, even merino (although they still get quite stinky after use!). I live in Georgia and in the summer heat/humidity your activities are limited - the best thing I can say about this shirt is that they enable me to work harder, longer. Plus the fit is like it was made for my tall lanky self - in other words, perfect. If you see them for $20-$25, don't think - just buy. You will get more than your money's worth.

Make no mistake, I get as much enjoyment out of these socks just walking around my house and picking stuff up w/ my toes as I do using them to run in!

That said, they are great for running/lifting/biking/whatevs. The first thing I noticed was that my shoes seemed bigger, because these socks fit so thin and light. Second, you begin to realize how much you use your toes for support while running because they can move so freely. Lastly, they breathe really well and seem to be holding up nicely.

Try 'em out, at the very least you can wear flips w/ them!

I'm 6'5" and wiry and this shirt fits me absolutely perfectly. I'd love to know who makes these because the length and fit are amazing for us tall folk. If you are skinny/athletic build your normal size will fit. Order a few because you will be wearing these out.
