Trust the exact chart.
A Large from one manufacturer is not automatically a Large from another. Product-specific manufacturer data wins over generic sizing advice.
MR POCKET FIELDWEAR & GOODS / FIT PROTOCOL
FIT IS A MEASUREMENT.
NOT A GUESS.
A logo can be standardized. Bodies cannot. Buy the exact garment, not the letter on the tag: use the product-specific manufacturer chart, compare it to something you already wear, then decide.
Four rules before checkout.
Decorated-to-order gear deserves thirty seconds of measurement before it deserves a place in your cart.
Measure a favorite.
Lay flat a garment that already fits the way you want. Compare chest, body length and sleeve measurements to the listed base item.
Account for the job.
Outerwear needs room for layers. Hot-weather tees may be worn looser. Athletic or trim cuts need more attention than a standard fit.
Custom means commit.
Personalized and decorated-to-order goods may have restricted return eligibility once production begins. Confirm size first.
Quick measurement protocol.
Use a soft tape when measuring your body. When comparing a garment, keep it flat and unstretched.
Chest / width
For a flat garment, measure straight across from armpit to armpit. If the manufacturer chart uses body circumference instead, follow that chart’s method.
Body length
Measure from the high point of the shoulder down to the bottom hem. Compare like-for-like garment styles.
Sleeve
Use the manufacturer’s stated measurement method; sleeve charts can begin at center back, shoulder seam or another reference point.
Layering allowance
If the garment will sit over a hoodie, thermal or work shirt, measure the combination you actually expect to wear.
MR POCKET rule: if this guide and the exact product manufacturer chart disagree, the product-specific manufacturer chart controls.
