Best baselayer - Smartwool Merino 250 Baselayer 1/4 Zip - Men's

I love this top so much! I have been using the product for more than a month. This was an amazingly warm base layer, needing only a light down jacket layer and of course a windproof jacket when stopped. The half zip was good at adjusting body temps during steep ascents. Great mid layer and warm. Great price and value. Subjectively great product and worth the product.
