I noticed the same thing about Ibex and Icebreaker pieces. The Ibex seems much better made and holds up better. Most of the Ibex is made in the US while the Icebreaker is made overseas. I have a few full zip Shaks and I wear them all the time. They never seem to get smelly or dirty, so don't need washing very often. They are very durable also. The norgie crew and zepher are other great Ibex pieces.
My next purchase may be a pair of el fito knickers for biking. What is the experience of those who have them? Thanks for the input.
