Clayton Keller Utah Mammoth Away Breakaway Player Jersey - White

Matchday isn't a date on the calendar — it's a state of mind. Throw on this Utah Mammoth jersey and you're already halfway to the stadium.

Product Overview & Specifications+
Designed to echo the on-field look without the on-field price tag, it delivers the pro-style aesthetic in a relaxed everyday fit.

Style That Reads from the Parking Lot

A classic look that won't date — clean colors, recognizable team markings, nothing fussy.

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

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

This Season’s Look

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

Built to Hold Up

Reinforced hems and colorfast graphics keep it looking sharp season after season.

Product Highlights & Craftsmanship+

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

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 away 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+

Ordering is simple and secure. If anything needs a second look, email us at jerseyhelp@hotmail.com and we'll sort it out. Every size option is listed on the product page, so you can pick with confidence before checkout.

A little care goes a long way — cold wash, air dry, and this jersey stays game-day ready for years.

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.
Does it come in other colors?+
This product page shows one colorway, but the team's home, away, and third looks are available across the store — check the collection for more options.
Is it a good gift for a sports fan?+
It's one of the safest bets in fan gear — a jersey is worn, seen, and appreciated. Customizing the name makes it a personal keepsake.

Your spot in the stands is ready — grab this Utah Mammoth jersey before your size is gone.
