JJ Peterka Utah Mammoth Women's Home Breakaway Jersey - Black

The stands are loudest when the whole crowd is dressed as one. Slip into this Utah Mammoth jersey and you're not just attending the game — you're part of it.

Product Overview & Specifications+
A straightforward fan jersey with the details that matter: clean team markings, breathable fabric, and a fit that works all day.

Comfort That Lasts All Matchday

Soft-touch fabric that feels broken-in from the first wear — no stiff, scratchy first weeks.

A Fit for Real Fans

Cut with a slightly tapered waist for a fit that flatters without sacrificing comfort — made with women's sizing in mind.

Built to Hold Up

Attention to the small stuff — even stitching, smooth collar line, and a print that doesn't crack after a few wears.

This Season’s Look

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

Product Highlights & Craftsmanship+

Perfect for stadium Saturdays, sports-bar Sundays, and every watch party in between. Pairs as easily with jeans and sneakers as it does with face paint and flags.

Whether it's Father's Day, a graduation, or just a 'thanks for being a fan' — this one lands.

Shop with Confidence+
  • Style: fan-version breakaway jersey with the home look of Utah Mammoth.
  • Fit: women's sizing; check the size chart for exact chest measurements.

True to size for most fans; if you prefer a looser, game-day layering fit, consider going one size up.

Frequently Asked Questions+

What you see is what you get — clear photos, honest sizing, and a fan version described exactly as it is. Every size option is listed on the product page, so you can pick with confidence before checkout.

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.
Which season is this jersey from?+
This design belongs to the this season campaign, bringing the current crest and colorway of the team's look.
Does it run small or large?+
It's built true to standard sizing. If you're between sizes, most fans take the larger one for comfort on long matchdays.
What's the difference between this fan version and the on-field version?+
This is a fan-version jersey inspired by the on-field look — same visual identity, with a comfortable everyday cut and a much friendlier price. It's designed for wearing, not just displaying.

Make it yours today — pick your size, hit the checkout, and get ready for kickoff.
