Jim Rahtz reviewed Brynje’s Wool Thermo Base Layers (shirt and longs) on a cold overnight backpacking trip. See what he had to say:
They continue to perform as promised: solid warmth in the cold and I stay comfortably dry while exerting myself. As with other wool garments, I don’t feel like I’m immediately overheating when I get back inside. Despite construction that’s 20% manmade material they still seem to have the other benefit of wool in that they tend to smell better than polyester clothes after a long wear.
