DESCRIPTION

The most brilliant fall colors only last for a week or two out of the year, so make sure you have the I/O Bio Merino Women's Signature Long-Sleeve T-Shirt for those must-hike days. The warm merino wool insulates you as you start crunching along the trail in the morning. Since the naturally replenishing fabric absorbs the moisture off your skin, you don't have to worry about a sweaty mid-day turning into a bone-chilling afternoon.
