JJ Peterka Utah Mammoth Home Breakaway Jersey - Black

Every NHL season writes a new story, and Utah Mammoth fans know better than anyone how quickly legends are made. Be part of it in this this season home look.

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

Quick-drying weave made for long matchdays — comfortable from the tailgate to the final whistle.

A Fit for Real Fans

Relaxed through the body with clean lines, so it layers neatly over a tee or under a hoodie when the evening cools off.

Style That Reads from the Parking Lot

Modern, streamlined, and unmistakably Utah Mammoth — it reads from across the parking lot.

Built to Hold Up

Clean team markings, tidy stitching at the seams, and a collar that holds its shape wash after wash.

Refresh your Utah Mammoth gear with this JJ Peterka Home Breakaway jersey from Prosportskit. Its eye-catching replica design is inspired by the uniform your Utah Mammoth wear on the ice.
Product Highlights & Craftsmanship+

From the tailgate to the grocery store, it quietly announces your allegiance without saying a word. 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: men'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.

Is this the same as what the players wear?+
It's the fan version of the on-ice look — same identity, made for comfort and everyday wear rather than the pro cut.
Is this jersey unisex?+
Yes, the cut works for everyone — most fans simply choose their usual size. Women may prefer sizing down for a closer fit.
How should I wash and care for it?+
Machine wash cold with like colors, turn it inside out, and air dry or tumble on low. Avoid high heat and ironing directly on printed details.

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