Montbell Merino Wool Plus Light Long Sleeve T-shirt Men's M size Blue Green Purchased about a year ago and used daily. I am selling it because I no longer need it. I do not plan to lower the price any further at this time. The following is taken from the Montbell website: This T-shirt uses thin Merino Wool Plus™, which combines the warmth of wool and the excellent quick-drying properties of polyester. It is useful for a wide range of purposes, such as an inner layer in winter or as an outer layer for trekking in cool seasons.
