Utah Mammoth Home Breakaway Custom Jersey - Black

Win or lose, loyalty doesn't take a week off. This Utah Mammoth home jersey is how you wear that loyalty where everyone can see it.

Product Overview & Specifications+
This is a fan-version jersey — cut for comfort, priced for real fans, and made to survive everything from stadium seats to backyard watch parties.

Comfort That Lasts All Matchday

Lightweight, breathable fabric keeps air moving on warm afternoons, whether you're in the stands or pacing the living room through extra time.

This Season’s Look

This this season version keeps the look current while staying true to what fans love about Utah Mammoth.

Style That Reads from the Parking Lot

The Black colorway stands out in a crowd without trying too hard.

A Fit for Real Fans

Standard fan cut with easy room in the shoulders and chest — built for all-day wear, not just the ninety minutes.

Built to Hold Up

Printed details are finished to survive the washing machine, not just the product photo.

What makes it stand out: We want fans to celebrate their fandom by customizing and personalizing certain products. For these customizable products, including jerseys, we invite customers to tell us how they would like their preferred name or other text to appear by typing that text into the field indicated.
Product Highlights & Craftsmanship+

Game night, gym session, or a casual Friday at work — it fits the day, whatever the day brings. Pack it for away trips — nothing beats spotting a fellow Utah Mammoth fan in a foreign city.

Surprise a fellow supporter with their team's colors — add their name and it becomes a keepsake.

Shop with Confidence+
  • Style: fan-version breakaway jersey with the home look of Utah Mammoth.
  • Fit: men's sizing; check the size chart for exact chest measurements.
  • Customization: Add your name and number at checkout for a truly personal piece.

When in doubt between two sizes, most fans size up for extra comfort over long matchdays.

Frequently Asked Questions+

Ordering is simple and secure. If anything needs a second look, email us at jerseyhelp@hotmail.com and we'll sort it out. What you see is what you get — clear photos, honest sizing, and a fan version described exactly as it is.

Keep it fresh: machine wash cold, inside out, and skip the iron on printed areas.

Need help? Email jerseyhelp@hotmail.com

Does it fit over a hoodie or base layer?+
Yes — the fan cut has room to layer, which is the usual game-day setup at colder arenas.
Is the color exactly as shown?+
We photograph every piece in natural light to keep colors true. Slight differences between screens are normal.
Are the crest details built to last?+
The team crest and markings are finished to hold up through wear and washing — wash cold, inside out, and air dry.
What fabric is this made of?+
It's a lightweight polyester-blend knit with a breathable, quick-drying feel — comfortable for warm days and easy to care for.

Show up, stand out, cheer loud — this Utah Mammoth jersey is one click away.
