Merino Clothing (base layers, etc)

Aside from Helly Hansen, I'm finding it difficult to find which brands have polypropylene base layers rather than simple poly ones. They all rebrand and give it a naf name; uberdry etc.

Anyone recommend brands they use that have decent synthetic (polypropylene) base layers?

According to wiki, the new generation of polyesters give better performance than polypro, with less of the high heaven stinkage.
For what it's worth.
