Wonderful cold weather base layer

I'm almost always a size M, and I purchased this in a M as well. It fits great and I don't have issues fitting it under most of my fleece and puffy layers. It's a little too bulky to fit under fleeces that fit very slim. I didn't like the NTS 250 under a Patagonia R1 (M), but it fits well under an R3 (M). The sleeves are more than long enough for comfort, but I would have liked thumbholes. The zip neck is deep enough to allow for some serious ventilation. I've worn it quite a few times biking/hiking hard and sweating a lot and it never really smells bad like synthetics quickly do. One thing to watch out for (as with all merino) is VELCRO. It latches onto this fabric and is very difficult to remove without pulling a lot of the threads out. There are a few spots on my sleeves where this has happened and it's easy to see the damage caused.
