Great Fit

One of the better underwater I have ever owned

John Milner

It sucks that this product is made in CHINA

Hi John, thanks for taking the time to write a review. Our manufacturers are indeed based in China. We've chosen to work with them due their consistent high quality in service and products they make. They also meet requirements which are important to us as a business - These not only include certificates that manufacturers must have and abide by but also methods in which they deal with recycling which go beyond a standard manufacturer. Best wishes, Crossfly.

My grandson was delighted with the underpants.

Extra room

The cross fly boxers do offer the up front room needed to keep you junk from being smashed and separation to keep things from sticking.

M Sadler
Better but not best!

The material is quite soft and comfortable and the fit is perfect however I was expecting a better design for the pouch. Design does not perform how it is described and just amounts to some extra material in the region to get bunched up, which it does get bunched up. Better than the general market offerings but not the best available.
