Sizing & Measuring
Measure once. Order right.
FR garments fit a little differently than standard workwear — they’re built to hang off the body for an insulating air gap. Use the charts below to size in. All measurements are in inches.
Step by step
How to measure.
- 1
Chest / Bust
Measure around the fullest part, keeping the tape level and snug — not tight.
- 2
Waist
Measure around your natural waistline (above the hip bones, below the rib cage).
- 3
Hip
Measure around the fullest part of your hips and seat.
- 4
Inseam
Measure from the crotch seam down to the bottom of the ankle.
- 5
Sleeve
From the center back of the neck, across the shoulder, down to the wrist with arm slightly bent.
- 6
Neck
Measure around the base of the neck where a collar sits.
Use a soft tape measure.
A cloth tailor’s tape gives the most accurate read. If you only have a steel tape, measure carefully and keep it flush to the body.
Measure over a base layer.
FR garments are designed to be worn over a light cotton or FR base layer. Measure that way for an accurate result.
Between sizes? Size up.
FR protection depends on a small air gap between the garment and skin. A slightly looser fit is safer and more comfortable.

Fit notes
A few things to know before you order.
Coveralls allow room over a base layer and tool belt — they are not slim-fit.
Cotton FR styles may shrink 3–5% after first industrial wash. Inherent blend FR shrinks less than 2%.
Hi-Viz styles meet ANSI 107 Class 2 when sized to fit per the chart — do not over-size hi-viz.
For program orders, request a sizing kit. We send one of each size for crew try-on.
Sleeve and inseam alterations are available on volume orders.
Returns: unworn, untagged items can be returned within 30 days. See Return Policy.
