As A lot as you like your silky baselayers, there's not A lot heat retention for those cool climbing, skiing, backpacking, snowshoeing excursions in the middle of winter. If your internal thermostat tends to run a little on the warm side, microfleece layering can be a bit stifling on extended trips. The Ibex Woolies Crew is a natural alternative to technical layering, but it doesn't rub you the wrong way when you wear it against your skin. This Woolies Crew is made with Ibex's proven 18.5 micron Merino wool fabric, a great lightweight rib material that's machine washable and incredibly soft. Unlike some fabrics that are chemically treated to facilitate moisture transfer, Merino wool is naturally moisture wicking, so you never lose the performance no matter how many times you launder. The cut is contoured to hug your torso without hindering your winter layering possibilities. Find out what hikers, climbers and anglers have known for several years--this Ibex Woolies Crew has a nice Merino fiber that's anything but baa-a-a-a-d.
