Men's Size Guide

Kaikuna size and measuring guide

Help! How do I figure out which size I should purchase?

Kaikuna pieces fit like most other active wear brands. You will find that the stretchy nature of the fabrics we use allows for some flexibility in sizing and is comfortable for varying body shapes. 

If you would like to have a looser fit, or feel you are between two sizes, order the larger of the two choices.

What if it doesn't fit once I receive it?

Remember, you want to feel good in your garment! Kaikuna will exchange sizes free of shipping charges. Send us an email at We will send you a shipping label that you can then use to return it to us. We only ask that you keep the tags attached, and do not wear it, within 30 days of purchase with instructions for us on how to make it better for you.

Measuring yourself for Sizing:

When measuring around the body, use a cloth tape measure and fit it comfortably around the area you are measuring. Make sure the tape measure is even and level all the way around your body. Stand straight with your feet  2 - 3 inches apart.

Chest - measure under your arms around the fullest part of your chest while relaxed.

Waist - measure around the narrowest part of your waist, approximately 2 inches above your navel.
