I paired it with the light merino wool bottoms and was very pleased. Weight to warmth is amazing.

Great product!! I was skeptical of all the hype about merino wool... but it is all true. These were extremely lightweight, but did a great job with maintaining body temperatures. Used during September early archery elk hunt. Did 6 days strait of hunting/hiking. Temperatures ranged from 30-70 and we hiked anywhere from 10-20 miles daily with about 3k elevation changes. I was never uncomfortable, wore either the ascent shirt, apex hoodie, and sometimes the kelvin light down jacket (no longer being made) with it depending on how the temperatures were looking. Even more impressive to me was that the base layers really did not smell at all. Im sold on it, will highly recommend to everyone. I hope Sitka will continue to produce more merino wool products, such as a t-shirt and more mid layers.

I think Sitka is really onto something with the Nylon/Wool combo. The quick drying property of nylon and the odor resistant property of wool work really well together. BUT no thumbholes for a $140 baselayer?
