Great base layer for sleeping or cool mornings - Smartwool Merino 250 Baselayer 1/4 Zip - Men's

purchased this top with the Smartwool Merino 250 Baselayer Bottom - Men's for a baselayer for cool nights camping/sleeping. They are very soft and comfortable wearing them around the house. Decided to try them out first - setting out on the patio for my morning coffee at 36°F while reading a book - with only the baselayer top and bottoms and some Smartwool socks. Still nice and comfortable after 30 minutes outside. Cannot wait to use these while out camping. Was concerned about the sizing given I am 6'3" and 190lbs, 34" waist - and typically require larger sizes due to larger shoulders and longer arms. Went with the sizes recommended on the Smartwool sizing chart and they are a prefect fit.
