The release says that it is inspired/designed by Dan Lanning's wife Sauphia who is a surviver of bone cancer, and she and her boys helped design the uniform.
Quoting Phil Hecken at Uni-watch:
Helmet: The helmet is matte black, with silver wings on either side. The nose bumper features Oregon’s trademark “O” logo incorporated with a yellow ribbon, which was based the concept sketched by Sauphia Lanning. The bumper also multi-colored stripes, each representing a different form of cancer. The same pattern with the words “STOMP OUT CANCER” is featured on the neck bumper.
Jersey: The jersey is yellow, and features several “harkback” elements from previous Ducks’ uniforms. The feather design is black with some gray/anthracite, while there is also some silver/gray diamondplate pattern below the wings. The base color is yellow, in acknowledgment of Sauphia’s battle with osteosarcoma, but the helmet, cleats, gloves and sleeve patches all feature a multi-color panel acknowledging victims of all cancers. Numbers are black in Oregon’s bespoke font. On the right sleeve is a “FLIGHT +FIGHT” logo patch, which has Sauphia’s “O”/ribbon concept. This was done at the urging of the Lannings’ middle son, Kniles. The patch also features silver wings on either side of the “O” logo. According to the team, “Sauphia’s original sketch of the “O” with a ribbon included the phrase “Take Flight + Fight.” She purposely utilized a plus sign, rather than the word “and” or an ampersand, because it mimics the sign of the cross that is an international symbol for health care providers. One sleeve of the uniform has a “Flight + Fight” patch, while the other has one reading “Stomp Out Cancer” under the image of a bell, which cancer victims ceremonially ring to mark the end of their treatment.” On the opposite sleeve is a similar logo, featuring a yellow bell with the words “STOMP OUT CANCER” beneath.
In his concept uniform, the Lanning’s oldest son, Caden, suggested the use of an ice cream cone. This can be seen, along with the formula for one of the chemotherapy drugs Sauphia took during treatment, on the compression sleeves available to the players.
Pants: The uniform pants are yellow and stripeless. The final Lanning touch comes on the cleats, which feature a multi-color panel on the tip, suggested by the Lanning’s youngest son Titan.
