Adding my 2 cents. Ordered the Aclima woolnet top and leggings last year from Varuste based on feedback from this forum. Process was simple and shipping was reasonably fast. Top has been fantastic. Used 6-10 times across hunts, ice fishing, and back country ski trips, in temps from 32 to -4F. As warm or warmer than any of the merino base layers I've ever tried, and sweat dries out SOOO much faster than with a solid base layer. Comfortable, not stinky like synthetics, and always draws comments from the peanut gallery. Highly recommend.
The leggings, on the other hand, I'm less impressed with. Not sure if I ever noticed them being any better than other solid wool/synthetic leggings in my closet (sweat less through my legs?). But the big thing is they started coming apart on me after the first use. First the cuff on one leg, and then maybe 3 uses/washes later the cuff on the other leg detached. I understand you can't expect fishnet to be super robust, but I'm pretty careful and don't abuse my gear, so I was disappointed, especially considering the tops have held up just fine so far.
