Great product, however, little odd sizing, long arms but far from it is a great product. To bad it is made in China. I have the Stinger pants and the jacket and they are made in Canada = GOOD quality, the chines are far off when it comes to quality, that's why TNF is not as good any longer.......and I know I have jackets and pants from the good old times, = made in USA and they are still good.
I have the Icebreaker Tech-Top 260 to compare with The Arcteryx Zip top....The Iceabreaker is great too, but the arms too short, the neck is very high and that is good, but one can get a feeling of someone is strangle you, the body could be little longer, the Arcteryx has long arms and the body is long too but the neck slightly too short.....with a longer neck and the Arcteryx will be optimal.
No smell, well I am not sure if you guys are sitting in front of the fire! I am out skiing, biking in sub zero temperatures in Sweden and both sweaters keeps me warm but I also sweet a lot and a wet merino wool sweater smells like a wet dog, but no smell when it is dry again.
