Getting the right size matters — especially with flame-resistant workwear that needs to fit comfortably over base layers while allowing full range of motion. Use the chart below to match your measurements to the correct UR Shield size.
| Size | Chest (in) | Waist (in) | Sleeve (in) |
|---|---|---|---|
| S | 34–36 | 28–30 | 32.5–33 |
| M | 38–40 | 32–34 | 33.5–34 |
| L | 42–44 | 36–38 | 34.5–35 |
| XL | 46–48 | 40–42 | 35.5–36 |
| 2XL | 50–52 | 44–46 | 36.5–37 |
| 3XL | 54–56 | 48–50 | 37.5–38 |
How to Measure
- Chest: Measure around the fullest part of your chest, keeping the tape level under your arms and across your shoulder blades.
- Waist: Measure around your natural waistline — the narrowest point above your hips.
- Sleeve: With your arm slightly bent, measure from the center back of your neck, across the shoulder, and down to your wrist.
If your measurements fall between sizes, we generally recommend sizing up for a more comfortable fit — especially if you plan to layer underneath. Welding aprons and gloves follow standard sizing; refer to individual product pages for specific fit details.

Getting the right size is one of the most important steps when purchasing flame-resistant workwear. Unlike everyday clothing, FR garments need to fit comfortably over base layers while still allowing a full range of motion for tasks like welding, grinding, and electrical work. A shirt that is too tight can restrict movement and reduce the protective air gap between layers, while one that is too loose may catch on equipment or leave gaps in coverage. Taking a few minutes to measure yourself properly ensures that your protective gear performs exactly as it should when you need it most.
When measuring for your FR clothing, always use a soft measuring tape and wear the type of underlayer you would normally wear on the job. For chest measurements, wrap the tape around the fullest part of your chest, keeping it level under your arms and across your shoulder blades. For your waist, measure around your natural waistline where your pants typically sit. Sleeve measurements should be taken from the center of your back, across the shoulder, and down to your wrist bone. These simple steps make all the difference in finding a comfortable, functional fit.
UR Shield designs its flame-resistant shirts with real-world work in mind. Whether you are an electrician, a welder, a griller, or someone who spends time on woodworking projects, your clothing needs to move with you. The sizing chart accounts for the fact that FR garments are often worn over thermal layers in cooler months or over a simple tee in warmer weather. Choosing a size that accommodates those layers without being baggy is the key to staying safe, comfortable, and productive throughout your entire shift.
Beyond the shirts themselves, proper sizing applies to all the protective gear in the UR Shield lineup. Welding aprons, leather sleeves, and gloves all need to fit correctly to provide genuine protection. An apron that is too short leaves your chest exposed, and sleeves that are too tight can cut off circulation during long work sessions. Taking the time to reference the size chart for each product you order helps ensure that every piece of gear works together as a complete protective system, giving you confidence on every job.
If you are between sizes or uncertain about which option to choose, it is generally recommended to size up rather than down for flame-resistant workwear. A slightly roomier fit is safer and more comfortable for extended wear, and it allows for layering during colder seasons. UR Shield is committed to producing quality protective clothing at an affordable price, and part of that commitment is helping customers find the right fit the first time. With accurate measurements and a clear understanding of the charts, you can shop with confidence and get back to work.
