10% of your purchase from items in our Breast Cancer Awareness collection marked with a pink ribbon will go to the Breast Cancer Alliance, a national foundation that has awarded more than $37 million to breast cancer research, fellowships, and screenings for underserved communities. Naturally warm, moisture wicking, odor resistant and temperature regulating, all thanks to the use of Merino wool. We designed the Thermo Merino Jersey for those who prefer a natural fiber with the performance attributes of their most technical pieces. Quarter-zip ventilation releases heat when needed while a merino/poly blend works to retain it at your core, making sure you’re always riding at the right temp. The 2-inch collar plays defense against draft and a dropped back hem provides extra coverage and warmth on chilly rides. Simply styled with a single rear zippered pocket for easy layering and made with long-lasting quality, you'll reach for this jersey season after season. Semi-fitted.
