Basis Stretch Merino results from our quest for the ideal extension to our well-loved Basis baselayer program. Just a bit lighter than our Basis Power Dry® Zip Neck at 200g/m2, this midweight top fits close to the body without being tight and is the perfect layering tool for ripping runs in-bounds or working up a sweat in the side and backcountry. At 18.5 micron, the merino fibers of this top are super fine, making it a year round, next-to-skin performance layer that wicks moisture, regulates body temp and stays odor-free. And with the addition of 5% spandex, you’ll appreciate the benefits of stretch and long-lasting durability.
