One of Smartwools best selling, and warmest, baselayer, just got a little more refined with an improved fit, chafe-free seam construction and panels that offer more comfort with a pack.
Care – Machine Wash Warm Gentle Cycle. Do Not Bleach. Tumble Dry Low. Iron Low. Dry Clean.
Mid 250 – Our warmest baselayer. Works as a single layer in cool weather or as a baselayer in cold weather
Best use as a baselayer on the long distance trails. This adds the most warmth and can double as a long sleeve shirt. I wore this the entire Appalachian Trial, even into some summer nights when it cooled down. I found it worked well in rainy weather, and would be the first one of my shirts to dry.
Pros – Warm base layer, light weight, can be doubled as a pillow long sleeve town shirt, came in handy during winter months in the higher elevations, dries easily, smell resistant
Cons – Could be considered unnecessary for true “Ultra-lighters”. Pricey! I honestly don't have many cons about this other than those, and I have used this on every single backpacking trip since the Appalachian Trail. It's my dinner shirt, when the night starts to cool, and the sun starts to set.
