"My new favorite! Thick and cozy."
— Sean P. (5/5)
"Good quality clothing, fast delivery, warm and cosy"
— Al (5/5)
"I was really looking for a heavy base layer and purchased these top & bottoms immediately. The quality is still obvious. Warm, but still breathable, the Size medium is just a bit snug on my 6'0"" frame but still fine. I just completed a cold weather exercise the military where it was -15C to -23C. This is what I wore all weekend."
— Sarge (5/5)

"V soft for merino - lovely and warm … perhaps a little shorter in the body than o had hoped but I have a very long back - would definitely buy another … if I could afford it !"

"This was purchased to replace an icebreaker that was in shreds from wearing teaching skiing. It is noticeably warmer than my other thermal tops. A definite must in the sigle digit temperatures."
