I too like that most of Ibex's things are made in USA from New Zealand merino.
I have Ibex lightwt woolie base layer top and also Smartwool lightwt base layer top. I've been wearing both for months, washed both quite a few times.
They both seem the same weight. The Ibex ones have raglan shoulder seams and long cuffs, whereas the SW sleeves have regular shoulder seams and a simple hem at the ends of the sleeves.
The SW ones have had two little holes where my fingers actually went right through the fabric when pulling them on (i've repaired them). Plus the SW ones have a problem with the hem stitching unraveling here and there. The Ibex base layers have not had either problem so far.
Still, they are small annoyances and I still like my Smartwool things a lot for other reasons.
