The Seattle Mariners look has survived coaching changes, roster turns and uniform tweaks. This alternate jersey carries it forward with Colt Emerson named on the back.
Shoulders are set for movement rather than for the mannequin. The mesh body hangs flat instead of bunching at the waist.
The design follows the Seattle Mariners alternate look — team colours, Colt Emerson name and number on the back, and the same silhouette worn in the stands. It ships with the name and number already applied — nothing to iron or assemble on arrival. Machine wash cold, tumble dry low, and it is ready to wear again the next morning.
It reads as Seattle Mariners gear anywhere, but the palette points straight back to Seattle, Washington and T-Mobile Park.
How to Wear It
Summer ballparks, 9-inning breathability, and the walk to the car after extra innings.
Care Guide
Machine wash cold inside out with a mild detergent, then tumble dry low. Skip fabric softener and high heat, and do not iron directly over the lettering.

How do I wash a Seattle Mariners jersey without damaging the numbers?
