Go-Lite makes nice stuff. I have a pair of synthetic pants I got online a few years ago when they were phasing out that particular model-they are full zip and really warm and if I remember right, weren't all that expensive, so at half off, whatever they have is likely a pretty good bargain even if the retail price seems a bit much. Priced Patagonia lately? Half off there is still pretty expensive. However, their Capilene stuff lasts forever if you take care of it.
