How to find your size
-
1. Get measured
Before you order, grab a tape measure and get your key stats
- Men: Measure your chest and belly at their widest points
- Women: Measure your bust, waist, and hips at their widest points
Accuracy now = better fit later

2. Pick your key measurement
- Men: If your belly is bigger than your chest, use your belly measurement
- Women: When it comes to bottoms, hip measurement is your most important one.
Between sizes? It's usually better to size down for bottoms. For tops, choose based on whether you prefer a snug or looser fit
-
3. Height matters
Men: Under 5'10"? A smaller size may fit better. Over 6'4"? You may want to size up
Women: Under 5'6"? Consider sizing down. Over 6'3"? A larger size might be comfier
