Some fan gear is about this season. This Utah Mammoth breakaway jersey is about the whole run — JJ Peterka, the colours, and a silhouette that has not needed reinventing.
This is the breakaway build rather than match-worn kit: the same Utah Mammoth look, a fan-weight mesh body, and a cut that layers over a tee. Sizes run men's S–3XL on the US scale. Machine wash cold, tumble dry low, and it is ready to wear again the next morning.
It reads as Utah Mammoth gear anywhere, but the palette points straight back to Salt Lake City, Utah and Delta Center.
The cut is relaxed through the chest with room left for a hoodie underneath. Mesh panels run the side seams to move air.

Frequently asked questions
What if the jersey does not fit when it arrives?
You are covered by our 30-day hassle-free guarantee with zero restocking fees. If the fit is not ideal, contact our support team and your first size exchange is completely free.
Will the hem ride up when I sit or reach for my drink?
Side splits at the waist hem keep the jersey from riding up when you sit, lean, or raise your arms.
Does the Utah Mammoth name and number come already applied?
Yes. The jersey ships with JJ Peterka name and number already heat-sealed in place — no ironing or assembly on arrival.
Is the fabric warm enough for cold rinks?
The jersey itself is breathable mesh; it is intended to be layered. Wear it over a long-sleeve tee or hoodie and you are set for cold rinksides.
