Soft and stretchable, the heavyweight Bamboo Performance Technology™ fabric offers a second skin fit for added support and comfort. Beyond sublime comfort, this amazing material offers natural temperature regulation, moisture wicking, anti-odor properties for extended wear and UPF 50+ protection. A wide waist band and flat seams will make these a dangerously comfortable bottom layer, whether riding across county, across town, or just hanging out around the house.
