I've worn this t and a crew neck travelling to and from Scotland to Botswana with some long layovers, and I wore it during my riding holiday, no odour. It's comfortable and attractive to wear, washes and dries quickly. I've also worn them whilst walking in the midi-pyrenees, much more comfortable than an ordinary t, wicking away sweat but not feeling chilly when a wind picks up. When you do need to remove a layer they fold into a neat package you can store in a pocket and any wrinkles fall out quickly so that it's ready to wear to go out in the evening. The lack of odour is amazing. Expensive, yes, but well worth it.
