Shirt Sizing
Member T-shirts cannot be exchanged or returned, so please carefully consult the size guide before selecting your membership gift. To compare measurements, place a shirt that fits you well on a flat surface and measure it across the chest, from armpit to armpit. Compare that number to our size guide for the best fit.
Note that this year’s women’s shirts are NOT the same style as previous years. While they remain more fitted than unisex shirts, they are not as fitted as the previous style. We recommend carefully consulting the size guide when making your shirt selection.
Please allow 6-8 weeks for domestic (U.S.) shipping and 7-9 weeks for international shipping.
