Sizing Guide

Krakatoa is designed to be flushed with your skin. There is no need to buy a size larger, as the front pouch eliminates "The Squeeze", and the 3-way stretch fabric conforms gently around your body. You want it snug, not loose, for maximum comfort.

Measure your waist size:
Wrap a measuring tape around your navel, at the narrowest part of your torso. Place a finger in between the tape and your body, for a comfortable fit.

*One thing to note, our XL is a bit larger, covering much of XL and XXL sizes.

In Between Sizes?
Krakatoa has a front pouch that conforms with your anatomy, so even if the undies feel snug around your legs and butt, your package is still comfy, so go for a smaller size for a snug fit. If you don't like it or the size was not correct, no worries, we will send you another pair on your correct size at no cost to you.
