I think they are pretty slick looking, and I kind of wish I could justify buying a the hoodie. The gray shirt also comes in a women's and youth as well.
Me and my son are going to STARRCADE in December so I may look at picking up a t-shirt then.
Here's a video about the partnership.
I also meant to share the fine print on the donation aspect:
WWE will donate 20% of the Sales Price (before applicable sales taxes) of Roman Reigns “We Believe” and "Tougher Than Cancer" apparel and 100% of the Net Proceeds* from sales of “Believe in the Fight” Bracelets sold on www.wweshop.com to The Leukemia & Lymphoma Society, an organization whose mission is to cure Leukemia, Lymphoma, Hodgkin’s disease and Myeloma, and improve the quality of life of patients and their families. For more information about The Leukemia & Lymphoma Society go to www.lls.org. While supplies last. This purchase is not tax-deductible.
* Net Proceeds means all revenue received from the sale of bracelets, less the cost of merchandise, fulfillment fees and any applicable credit card processing fees.
