Kairos Singlet Size Finder
Find your Kairos singlet size
How we suggest a size: weight gives a starting point, height checks whether that size may be short, and your fit preference makes the final adjustment. These are estimates; compare the measurements and choose the fit your wrestler prefers.

*Weight guide: These ranges are Kairos estimates for a starting size, not manufacturer weight recommendations. “—” means no estimated weight band is available; compare garment measurements and contact Kairos for help.
How to measure: Chest and waist are approximate singlet circumferences measured flat and doubled; they are not body measurements. Body length runs from shoulder to leg hem. Stretch and body proportions affect fit.
Choosing a size: Height and torso length can call for a larger size even when weight points smaller. For example, at 5′10″ and 130 lb, an adult Medium can provide needed length. At 5′6″ and 126 lb, an adult Small can suit a snug fit, while a longer torso or roomier preference can favor Medium. Choose the fit your wrestler likes.
