I have used everything from patagonia, lifa, ice breaker, smart wool , ski doo, columbia, mountain hardwear and tons of others and the best for the money is Helly Hansen Lifa, the reason is that the material will not axcept water so it wicks it away from your skin, keeping you dry. Layer is the best. I live in bc and use a short sleeve lifa with a long sleeve over top then my shell, perfect in every condition except when it gets really cold minus 20 then use a warm layer under shell. Lifa is also the cheapest with ice breaker being the most and I find with wool it gets heavier and does hold moisture...it feels nice though.
