I sweat more than most, it seems. So I have been looking for a base layer that excels at moisture transfer and has the benefits of Merino wool. This item has exceeded my expectations and is by far the best base layer I have used (and I’ve tried synthetic, Merino and Merino/synthetic blends) for strenuous back packing in mild winter conditions. My only wish is that it was an inch or so longer for my longer back (I typically wear tall shirts). I think it runs a little smaller than many other brands so if you think you are between sizes or not very trim you might consider sizing up a size from what you typically wear.
