      Size Guide

      Size Guide

      The complete fit handbook for Gridiron Kit jerseys — measured to the inch and the centimeter so you order the right size with total confidence.

      Quick rule: Not sure between two sizes? For a game-day, loose fit size up. Every jersey is covered by our 30-day return policy if the fit isn't right.

      1 · How To Measure

      Wear minimal clothing and stand relaxed. Use a soft (cloth) tape measure, keep it level and snug but not tight. All our size charts use body measurements, not garment measurements — so measure your body, not a shirt you own.

      Chest widest part, arms down Body Length shoulder → hem Waist natural waist / navel Hips widest seat Inseam crotch → ankle Sleeve shoulder → cuff
      1

      Chest

      Wrap the tape around the fullest part of your chest, arms relaxed at your sides. Keep it level across the back.

      2

      Waist

      Measure at your natural waistline, roughly level with your navel. Don't suck in.

      3

      Body Length

      From the highest point of the shoulder (near the neck) straight down to the hem.

      4

      Sleeve

      From the shoulder seam out to the cuff — most relevant for jerseys.

      5

      Hips

      Around the widest part of your hips/seat, feet together. Useful if layering bottoms under pads.

      6

      Inseam

      From the crotch seam down the inner leg to the ankle. Reference for padded-game layering.

      Units: 1 inch = 2.54 cm. Our charts show both — inches first, centimeters in small gray text. When between numbers on the chart, round up to the larger size for a comfortable fit.

      2 · Men's Jerseys

      Body measurements in inches (and cm). "Fit" describes how the cut sits relative to your body.

      Pro tip: our men's jerseys are cut to layer over shoulder pads, so they run slightly roomy. For an off-field, body-skimming fit, consider sizing down one.

      3 · Women's Jerseys

      Tailored through the torso with a slightly tapered waist. Measurements in inches (and cm).

      SizeBustWaistHipsBody Length

      Women's jerseys run true to the chart. If you're between sizes and prefer a relaxed game-day look, size up; for a fitted look, stay true.

      4 · Youth Jerseys

      Chest measurement with recommended height and age range. Measurements in inches (and cm).

      YXL41"104 cm60–64"152–163 cm14–16
      Tip for growing kids: If your child is between sizes or near the top of a range, size up — jerseys layer easily and they'll get another season of wear. A YXL often bridges nicely into adult Small.

      5 · Height & Weight Fit Finder

      The fastest way to pick a size if you don't have a tape measure. These are starting points — athletic/wide builds should size up.

      Men

      5'9"+180–200 lb2XL

      Weight is only a guide — a 185 lb powerlifter and a 185 lb runner need different sizes. Always trust your chest measurement over the scale.

      6 · Big & Tall Jerseys

      For broader builds and longer torsos. "Tall" adds ~2" to body length and ~1.5" to sleeves; Big adds chest/waist room.

      8 · Authentic vs. Replica — Which Fit?

      Authentic (Game Fit)

      Cut to layer over pads, like the pros wear on the field.

      • Slightly loose through the body and sleeves
      • Longer sleeves for pad coverage
      • Stitched, durable numbers & names
      • Best for: game day, layering, true fan look
      • Size down if you want a snug, off-field fit

      Replica / Throwback (Tailored)

      Everyday fan wear, closer to the body.

      • More tailored through the torso
      • Shorter, lighter sleeves
      • Applied numbers suited to casual wear
      • Best for: casual wear, gifting, youth
      • True to the chart — order your normal size
      Custom name & number jerseys are made to order in your selected size. Authentic custom runs about one size larger in feel than Replica custom. Double-check the measurements before ordering — personalized items follow the standard return rules only if defective.

      9 · Between Sizes? Decide Here

      Use your build and how you'll wear it to break the tie.

      Athletic / broad shoulders

      Chest is the priority. Size up so the chest isn't tight; the waist will be a touch loose but looks intentional.

      Slim build

      Stay true to the chart, or size down one for a sharper silhouette (Replica especially).

      Wearing pads / layers

      Size up at least one from your tee size — Authentic jerseys are already cut for this.

      Gift, unknown size

      Pick the recipient's usual tee size; our 30-day return covers exchanges if needed.

      Long torso

      Go Tall (LT/XLT/2XLT) or simply size up — body length grows with the size.

      Prefer loose / oversized

      Size up one to two for the relaxed streetwear look.

      10 · Jersey Fabric & Feel

      • Authentic Game Jerseys: 100% polyester breathable mesh — wicks sweat, holds its shape, lightweight for all-season wear on the field or in the stands.
      • Replica / Throwback Jerseys: lighter poly-blend performance knit with a softer hand — built for everyday fan wear and all-day comfort.
      • Custom Name & Number Jerseys: made on the same Authentic or Replica body you choose; numbers are stitched (Authentic) or applied (Replica) for lasting wear.

      11 · Jersey Care

      • Turn the jersey inside out before washing.
      • Machine wash cold on a gentle cycle; mild detergent only.
      • Hang dry — avoid tumble dryers and direct high heat.
      • Do not bleach, iron directly on numbers, or dry-clean.
      • Store flat or on a wide hanger to preserve shoulder shape.

      Following these steps keeps stitched numbers and prints intact season after season — and protects your 365-day warranty coverage.

      12 · Fit FAQ

      Do your jerseys run true to size?

      Replica jerseys run true to the size chart. Authentic jerseys are cut roomier to fit over pads, so they feel about one size larger than a standard shirt — size down if you want a fitted look.

      Will the jersey shrink after washing?

      Our polyester mesh and knit fabrics are pre-shrunk and resist shrinkage. Following the cold-wash, hang-dry care instructions, you should see no noticeable shrinkage.

      I'm between two sizes — which should I pick?

      For a relaxed game-day fit, size up. For a tailored everyday look, size down (Replica) or stay true (Authentic). See section 9 for build-specific guidance.

      Can I wear shoulder pads under a Replica jersey?

      You can, but it'll be snug. Authentic jerseys are designed for pads; for padded wear we recommend Authentic or sizing up in Replica.

      What if the size I ordered doesn't fit?

      Unworn jerseys with tags can be returned within 30 days for an exchange or refund. See our Return Policy. Custom name/number jerseys are returnable only if defective.

      Do women's jerseys run small?

      No — they follow the women's chart in section 3 and run true. If you're between sizes and want a looser fit, size up; for a fitted look, stay true.

      How do I get a longer length if I'm tall?

      Choose our Tall sizes (LT, XLT, 2XLT) which add about 2" of body length and 1.5" of sleeve, or simply size up.

      NFL Football Fan Jersey

      Jaxon Smith-Njigba Seattle Seahawks Youth Game Jersey - College Navy

      Game | Navy

      Pulling on Seattle Seahawks colors changes the whole mood of a game day. That is really the point of this jersey.

      The Seattle Seahawks Game Jersey in Navy is a fan game built for people who actually watch the games. It keeps the on-field look fans know - team colourway, clean lettering, familiar number placement - while staying light and easy enough for a full day of wear.

      Which club

      This one is all Seattle Seahawks. The team colourway, the lettering and the number placement all point back to the club, so nobody has to ask who you support.

      VersionGame fan build

      SizesMultiple sizes available - see the size options on this page

      This listing is the Youth (kids) version, cut and graded for kids and teenagers.

      Who it is for

      The NFL buyer is usually buying for a reason rather than browsing: Sunday fixtures, a tailgate, a gift for someone who already has three. What settles the choice is whether the shirt looks right on the body and survives regular washing, not a long specification list.

      Details that matter when choosing this Seattle Seahawks jersey

      Start from the Seattle Seahawks Game jersey and the rest of the choice narrows quickly: Seattle Seahawks colours, team styling, and a cut that works with jeans as easily as with shorts.

      The Seattle Seahawks jersey is the base piece of the Seahawks range: the same team colourway, number placement and lettering fans expect, cut in a shape you can wear all day.

      Shoppers filtering by NFL football jersey will find this alongside every other NFL football top we stock, in the same sizes and the same fit.

      Seahawks match day jersey searches usually come down to two questions - does it fit, and is it the right shirt for the occasion. This Navy game answers both: kids and teenagers sizing, a lightweight knit, and a colourway that reads clearly without being loud.

      The Jaxon Smith-Njigba jersey is the version supporters pick when they want the Jaxon Smith-Njigba look without the player-issue cut - same name and number placement, much easier to wear.

      Gifting notes

      It is the present that gets worn immediately rather than put in a drawer.

      Build quality

      The collar keeps its shape instead of stretching out after a few wears.

      Comfort first

      The hand feel is soft rather than slick - closer to a well-worn tee than to a technical shell.

      Questions people ask about this Seattle Seahawks jersey

      How should I care for the Seattle Seahawks jersey?
      Cold machine wash inside out, hang to dry, and skip the tumble dryer - heat is what cracks printed lettering.
      Where does the Seattle Seahawks jersey ship from and can I return it?
      It ships from the warehouse listed on this page, and unworn items in the condition they arrived in can be returned within the stated return window.
      Why do people buy Seattle Seahawks shirts as gifts?
      Football is the easiest league to buy for someone else: the colours are widely recognised, so the size and fit matter far more than picking the right model. This game is cut for kids and teenagers - check the size options on this page before ordering. Supporters who watch together tend to buy more than once, so the first shirt is judged on whether it will still look right a year later.
      What is the Seattle Seahawks game jersey?
      It is a navy Seattle Seahawks game in the colourway, made as a supporter game for kids and teenagers.
      Which sport and league does the Seattle Seahawks jersey belong to?
      The Seattle Seahawks jersey is NFL football - it is listed under NFL and cut for football rather than for general training wear.
      What exactly is the Seattle Seahawks Game Jersey in Navy?
      It is a fan-version football jersey inspired by the Seattle Seahawks on-field look, offered in the navy team colourway. It is made for supporters to wear on game day, at training or as casual clothing, not as match-worn kit.
      Is this a match-worn or player-issue jersey?
      No. This is a game made for supporters: a relaxed cut and everyday comfort rather than the heavy technical build players wear. It follows the Seattle Seahawks look in colour and layout, but it is not on-field kit.
