SmartwoolMen's Merino 150 Long Sleeve Baselayer(Return to Product Page)

Great design and execution for this base layer, comfortable and warm - perfect for temps in the 50s with a good jersey. For the colder months I would rather use 250 weight fabric but I've layered with this one on 35 degree days and stayed warm enough.

I wore this under a long sleeve during cold weather. I was a great base layer and I would not hesitate to get another if I needed one. My cycling buddy always raves about wool and now I know why!

While technically this is a base layer, I wear this as a top. It is comfortable and just the right thickness to take the cool edge off.

If it's in the 50's or low 60's, this is an ideal weight. You can roll the sleeves up or down and that can keep you at the ideal temperature.
