The shirt is a great fit for the gym or the streets. It's very well fitting, so it looks good wearing around, and feels very durable so far, so I'm not worried about ruining it. While it fits well, it is not too tight or restrictive, so of course it makes for a fantastic climbing shirt. I have not tried it outside, but so far it performs in any environment and it hasn't had any problems grazing against gym walls. Most importantly, I love the gray color and the great fit, the shirt makes me feel very confident, which is not something I usually say since I normally don't care about my clothes :)
My only complaint is that while most things including the famous magdust are fairly priced considering their exceptional quality, and this is a very high quality shirt, I still think it is hard to justify 65$. Even comparing to Rungne jackets that are only slightly more money or other higher end athletic shirts, and Rungne pants that go about the same range as a good pair of jeans or higher quality pants, it just seems a bit pricey compared to other Rungne products and equivalents. None the less, It did make for a fantastic Christmas present, and is a 5 star shirt for sure. I'm definitely interested in dipping into more Runge apparel in the future if this shirt gives any good signs.
