How to measure
- Chest: wrap a tape measure around the fullest part of your chest, under your arms, keeping the tape level. Don't puff up — breathe normally.
- Waist: measure around your natural waistline, where you'd wear your belt.
- Length: from the top of the shoulder (next to the collar) straight down. The Zip-Polo is cut to end mid-fly — long enough to stay put, short enough to wear untucked.
- No tape measure? Measure a shirt that fits you well, laid flat, and double the chest number.
How the fit runs
The Zip-Polo is a tailored athletic fit: trim through the body with room in the shoulders and chest. The 4-way stretch knit gives you more range than the numbers suggest — it moves with you rather than restricting you.
Between sizes? Size up. You'll keep the clean line and gain a more
relaxed drape. Most customers who sit on a boundary prefer the larger size
for all-day wear.
