Size Charts

Sizing is the single biggest reason people end up disappointed with printed apparel, and because everything here is made to order, we can't take a shirt back because it came up small. So spend two minutes here. It is the difference between a shirt you live in and a shirt in a drawer.

The fastest way to get this right

Forget your t-shirt size. Every brand lies differently. Do this instead:

1. Find a shirt you already own that fits you the way you want this one to fit.
2. Lay it flat on a table, front up, and smooth it out.
3. Measure straight across the chest, one inch below the armhole, seam to seam.
4. Find that number in the Chest column below. That is your size.

That works because the Chest column is the same measurement — garment laid flat, one inch under the arm, seam to seam. You are comparing like to like.

No tape measure? Use the chest range table below instead — measure around the fullest part of your chest, arms down, tape level. Or just email us what you normally wear and we will tell you which way to go.

Every measurement on this page is the garment laid flat, not your body, unless the table says otherwise. Manufacturing tolerance is about an inch either way — that is normal for cut-and-sew apparel, not a defect.

The charts

Classic cotton tee

I Don't Do Heights I Own Them · My Office Has a 500 Foot Commute · Closer to God Than Your Cubicle

Premium ring-spun tee

American Flag Tee · Distressed Flag Tee · Blue Flag Tee · High Risk Higher Pay — Premium

Cut slightly trimmer through the body than the classic cotton tee, and lighter on the shoulder.

Triblend tee

Tower Hand Tee — Triblend

The softest and lightest of the tees. Drapes closer to the body than the cotton styles.

Performance tee

Safety First Tee

Polyester, not cotton. Cut with a little more room through the chest and it does not shrink.

Long sleeve tee

Tower Logo Long Sleeve · Classic Logo Long Sleeve · Climb High Long Sleeve · We The People Long Sleeve

Sleeve is measured from the centre of your back, across the shoulder and down to the cuff — not from the shoulder seam.

Heavy hoodie

Classic Logo Hoodie

Roomy on purpose — cut to go over a shirt.

Midweight hoodie

Safety First Hoodie — Midweight

Lighter and softer than the heavy hoodie, cut about an inch longer in the body.

Tank

Classic Logo Tank · Classic Logo Tank — Premium

If you would rather measure yourself

Measure around the fullest part of your chest, arms down, tape horizontal. Then:

Between two sizes? Go up. Nobody in this trade has ever complained a shirt had too much room in the shoulders.

Fit notes worth knowing

• The rash guard runs small and is meant to be tight. Order a size up unless compression is what you are after.
• All-over-print jerseys run in their own sizing — 2XS through 6XL. If you are ordering one, email us and we will send the numbers for that specific piece.
• Hats are one size with an adjustable closure. The truckers and snapbacks fit roughly 21⅝″–23⅝″ around.
• Cotton shrinks a little on the first hot wash. Ours are pre-shrunk, so it is minimal — but wash cold and you will not find out.
• Heather colors contain polyester. They run true but feel a touch lighter.

Still not sure? Ask. Email sales@altitudeiron.com with the shirt brand and size you normally wear and we will tell you which one to pick. That costs us nothing and saves you a shirt you can't return.
