      1. How to Measure

      Take these measurements over a thin t-shirt (never 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 parallel to the floor and don't puff your chest out.

      2. Waist

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

      3. Hips

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

      4. Body Length

      Measure from the highest point of your shoulder (next to the collar) straight down to where you want the hem to sit.

      5. Sleeve Length

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

      6. Inseam (Pants)

      Measure from your crotch straight down to your ankle bone along the inside of your leg to find your ideal pant length.

      2. Fit by League (Overview)

      Each major sports league designs jerseys with a distinct traditional silhouette.

      League Cut Style How It Should Feel & Fit Advice
      Soccer Athletic / Slim Close to the body. If you are between sizes or prefer a streetwear look over t-shirts, size up.
      NBA Basketball Standard / Long Relaxed through chest and shoulders with an elongated hem. True to size; size up if layering over hoodies.
      NFL Football Roomy / Boxy Classic oversized game-day cut with broad shoulders. Plenty of room for hoodies. Order true size or size down for tailored fit.
      MLB Baseball Full / Button-Front Relaxed traditional baseball cut with extra room in chest. True to size; fits comfortably over casual layers.
      NHL Hockey Very Loose / Generous The loosest cut of all leagues. Wide through body with extra-long sleeves. Never size up; order true 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 us your height, chest, and waist measurements via email to jerseycare@outlook.com. Our specialists will check your dimensions before dispatch and ensure you receive the right fit.
      I am between two sizes — which should I choose?
      When in doubt, always size up. A slightly roomier jersey is comfortable, breathable, and easy to layer over t-shirts or hoodies. A jersey that is too tight rarely gets worn.
      Do jerseys shrink after washing?
      No. Our jerseys are made of premium recycled technical polyester mesh which is dimensionally stable and pre-shrunk. As long as you wash in cold water (30°C) and hang dry, shrinkage is less than 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 this game-day look. Your normal t-shirt size will easily accommodate a standard hoodie. If you wear an extra-thick fleece hoodie, consider going up one size.

      12s Seattle Seahawks Home Jersey (Navy Edition)

      There is a particular moment when a new jersey stops being merchandise and starts being yours. For most 12s Seattle Seahawks supporters, that happens somewhere between the first wash and the first matchday.

      Someone on our team has worn this to a match, a wedding after-party, and a flight. It survived all three.

      Why supporters pick this one
      • Opacity tested: not see-through under stadium lighting
      • Creased? It falls flat on a hanger without ironing
      • Sizing consistent across the full NFL range
      • Ships in plain packaging — suitable for gifting
      • Official 12s Seattle Seahawks crest with NFL colourway and trim detailing

      Before you choose a size

      The single most common reason for a return is expecting a player-issue fit. This is the fan cut: comfortable, forgiving, and designed to be worn for hours rather than ninety minutes.

      It will not shrink meaningfully. The recycled polyester is pre-shrunk and dimensionally stable, so a cold wash and natural dry change the fit by less than one percent.

      Custom printing & personalisation

      Delivered blank, so you can add your own name and number through any standard league lettering service, or wear it exactly as it is.

      Design accents: Navy base colourway

      How it fits and feels

      The fit is consistent across the size range — no sudden jumps between medium and large the way some replica cuts have.

      Smooth on the outside, lightly textured on the inside. The contrast helps it sit off the skin rather than against it.

      The crest is heat-applied rather than embroidered, which keeps it flat against the body and stops it scratching under a jacket.

      Where you will wear it

      Works as a top layer in autumn and a base layer under a coat in January.

      A safe gift for the 12s Seattle Seahawks supporter who already owns everything, largely because it is the home version they probably do not.

      Care and washing

      Wash with the collar buttoned and the shirt turned inside out. It reduces stress on the placket and protects the crest.

      Shipping, sizing and returns

      Free shipping on orders over $57 · Flat $7 shipping below $57 · Dispatched in 7-15 business days · 30-day free returns

      Sizing is consistent across the NFL range, so if you already own a 12s Seattle Seahawks jersey you know your size. Exact measurements are in the size guide.

      Common questions
      Does the crest peel off after washing?

      It should not. Stitched tackle-twill numbering & crest is applied under pressure rather than simply ironed on. Avoid tumble drying and it will outlast the season comfortably.

      Does the price include taxes or duties?

      Product price excludes local import duties, which vary by destination and are handled by the carrier.

      What detergent should I use?

      Mild liquid detergent, nothing more. Skip softener entirely; it clogs the mesh and cuts airflow.

      From our team to yours
