Rated 5 out of 5 by from First in class base layer Sitka gear has taken outdoor clothing to a new level. I have purchased a number of their systems for waterfowl hunting which is the worst of conditions for any hunting or fishing experiences and I have not been left uncomfortable since. The optifade patterns are revolutionary and while quite costly is worth the added cost as it will not leave you cold. This merino base layer was enough to keep me comfortable with only the base layer and a light down vest is 25 degree weather. It is soft and comfortable as a base layer even being merino wool as it has a layer on the inside that keeps it soft. Despite it being merino, even the outside is very soft and subtle. Sitka puts so much thought and design into everything that they leave nothing to be desired with their clothes. They take customer input and change things when a better design feature is suggested. You simply can’t go wrong with them.

Rated 5 out of 5 by from Comfortable, Warm and Good Quality Under Garment This is a great warm under garment for layering up for cold weather coyote hunting. I was in freezing whether with just one additional layer and never got cold. It was just what I needed.

Rated 5 out of 5 by from Sitka makes another great next to skin product. I used my newly purchased Sitka merino heavy weight wool bottoms and tops last weekend. Coupled with the Sitka gradient pants and tops. Completely warm with less bulk. Orvis has a fantastic customer service department. Was shipped out the next day. There’s nothing out there better then Sitka gear. And trust me, I’ve used them all over the past 30 years of waterfowling.

Rated 5 out of 5 by from Very warm. Great quality. I was looking for a warm under garment for layering up for cold weather deer hunting. It was the perfect choice. Next year I’ll add the matching pants.
