Size Guide

FANGEAR PRO SIZE GUIDE

The right size, the first time. All charts below use international standard body measurements — in inches and centimeters — covering jerseys, shorts, jackets, hoodies, and pants across NFL, NBA, MLB, NHL, NCAA, and Soccer.

1. HOW TO MEASURE

Take these measurements over a thin t-shirt (never bulky outerwear), standing relaxed. Use a soft measuring tape.

1. Chest (Most Important)

Measure around the fullest part of your chest, directly under the armpits. Keep the tape level with the floor and do not puff your chest out.

2. Waist

Measure around your natural waistline — the narrowest part of your torso, typically above the belly button. Key for shorts and pants.

3. Hips

Stand with feet together and measure around the fullest part of your hips and glutes. Crucial for track pants and basketball shorts.

4. Body Length

Measure from the highest point of your shoulder (beside the collar) straight down to where you prefer the bottom hem to rest.

5. Sleeve Length

For long-sleeve kits, windbreakers, and jackets: measure from the shoulder seam down to your wrist with your arm slightly bent.

6. Inseam (Pants)

Measure from the crotch point straight down to your ankle bone along the inner leg seam to find your ideal pant length.

2. FIT BY LEAGUE (OVERVIEW)

Each major sports league designs jerseys with its own distinct traditional silhouette.

League	Cut Style	How It Should Feel & Sizing Advice
Soccer	Athletic / Supporter Slim	Close to the body. If you are between sizes or prefer a loose Blokecore streetwear look over t-shirts, size up one.
NBA Basketball	Standard / Elongated	Relaxed through chest and torso with an extended back hem. True to size; size up if layering over hoodies.
NFL Football	Roomy / Boxy Tailgate Cut	Classic oversized game-day cut with broader shoulders. Plenty of room for hoodies. Order true size or size down for a tailored look.
MLB Baseball	Full / Button-Front	Relaxed traditional baseball profile with curved droptail hem and extra chest room. True to size; fits easily over base layers.
NHL Hockey	Very Loose / Generous	The roomiest cut of all leagues. Wide across the torso with wide sleeves. Never size up; order your normal t-shirt size.

14. FREQUENTLY ASKED QUESTIONS ABOUT SIZING

What if I'm not sure which size to order?

Order the size you think fits best, then simply send your height, weight, and chest measurements via email to fangearprohelp@outlook.com. Our specialists will check your physical stock measurements before dispatch and calibrate your size if needed.

I am between two sizes — which should I choose?

When in doubt, always size up. A slightly roomier jersey provides better airflow, supreme matchday comfort, and allows effortless layering over t-shirts or hoodies. A jersey that is too tight rarely gets worn.

Do the jerseys shrink after washing?

No. Our jerseys are crafted from premium technical polyester mesh that is dimensionally stable and pre-shrunk. As long as you wash in cold water (30°C / 85°F) and air dry naturally, shrinkage is under 1%.

Can I wear an NFL or NHL jersey over a hoodie?

Yes! NFL and NHL jerseys are traditionally cut roomy and boxy specifically for cold-weather layering. Your normal t-shirt size will easily accommodate a standard hoodie. If you wear an extra-heavyweight fleece hoodie, consider stepping up one size.

Product Overview

Built for cold rooms, the construction balances warmth with enough give to move in. From the season opener to the playoff push, the jersey is standard wear.

Replica means the look without the compression: a roomier torso, a softer hand, and a drape that suits everyday wear. In summer it breathes well enough to wear on its own, and it does not sit heavy once the sun drops.

Micro-perforated mesh panels move air across the torso, so heat has somewhere to go.
Pre-shrunk fabric stays true to size after a cold wash and a natural dry.
A structured shoulder line that keeps its silhouette on a hanger and on the body.
Flatlock stitching in high-friction areas cuts down on chafing under a backpack or in the stands.
Moisture-wicking knit pulls sweat away from the skin and dries quickly afterwards.

Edition & Printing Details

Supplied with Clayton Keller's name and number pre-applied in the team's league typeface, ready to wear straight from the bag. This listing does not include custom name-and-number printing; the shirt arrives exactly as pictured.

Frequently Asked Questions

How does this jersey fit? +

Youth sizing maps to age bands, and the cut leaves room to grow without looking oversized. For the longest wear, match the chest measurement rather than the age label.

What is the best way to wash and care for this shirt? +

To protect the graphics and the fabric structure, machine wash inside out on a gentle cold cycle, or hand wash. Air dry naturally and avoid tumble drying or ironing directly on the graphics.

What are the shipping and return terms? +

Standard shipping is tracked and insured and normally lands within 7-15 business days. Free shipping applies to orders of $57 or more (a flat $7 fee below that). You have 30 days for a return or a free size swap, with no restocking fees.

What if the jersey does not fit? +

If the sizing misses, we offer free exchanges and full returns for 30 days, with no restocking or handling charges.
