3-Pack: Crossfly IKON 6" Boxer - Green Marle

Fit tips

We recommend you go down a size in this style if you sit in-between sizes to get a more contoured fit as the modal fabric is very stretchy. (Ie: if normally a S/M, please opt for S)

Small pouch / fly to hard to get over

They say to go one size smaller, they do fit pretty good, pouch is very small and I did not like them, I will be sending back also the fly is very hard to get over. I have some underwear with the "H" fly and they work great but not this one.

Extremely soft but big

Extremely soft and comfortable but they run large. As a 32-33 waist the mediums were loose. Waiting to hear from customer service about trying a small. Compaired to all others I’ve tried, These are the most comfortable, form fitting, moisture wicking even after daily 5 mile walks, I have ever worn. Need to try a small to compare fitting

Just too big.

I took the advice of others and ordered a smaller size but they are still too big.
