Perfect for hikes in our favorite National Parks, the Capilene Midweight Baselayer Set is our go-to first layer of defense for our little ones because it supplies the attention to detail that we’ve come to expect from Patagonia. The HeiQ anti-odor technology keeps funky smells to a minimum, while the breathable synthetic fabric layup is comprised of 100% recycled polyester to limit the garment’s impact on the environment.
