I've got about five of these Smartwool tees in both long and short sleeves and they are great. They are perfect for casual workouts and travel and wear well. I buy one anytime they are on sale.
Smartwool makes a tshirt that will last a good 5 years of consistent wearing. It's light and soft and there is no reason to ever wear anything else.
Wears well. After 40 mile ride still does not smell and dries quickly. 6'2, 210 am wearing XL and fits nicely
