Question 1 of 4

Quick Reference Guide

Day vs. Night

Daytime errands or workouts? Pull-ups are your go-to. Overnight peace-of-mind? Tab-style briefs win.

Fit & Feel

Pull-ups look/feel like regular underwear for discretion. Tab-style briefs offer adjustable tabs for a tighter seal.

Absorbency at a Glance

Pull-ups: up to ~8 cups. Tab-style briefs: up to ~10 cups. Choose based on how often and when leaks happen.

Quick Size Guide

Sizing affects your seal (and leaks!). Measure the widest point of your waist or hips and use the largest number to choose a size. If you’re between sizes, most shoppers prefer sizing up for comfort with a snug seal.

M: 31–47” L: 43–59” XL: 47–67”
