I like the COSTCO Paradox poly and Merino blend zip neck tees and long johns. I find for the $20 Canadian price for the tops and less for the bottoms that they are 1/5 the cost of KUU merino tops and they last 5 times longer and dry 5 times faster. I back pack hunt, cross country ski, hike etc and the Paradox stuff works way better than Merino for me. The exception being that I love the COSTCO Merino wool socks and Ice Breaker Merino boxer shorts.
