Very nice.
My junk has never felt better. These underwear are just superb. I threw all my other pair away and replaced them with Sheath underwear.

Worth it
Great customer service and an awesome product to switch to.

So comfortable!
These are the best! The dual pouch is nice, and I actually like the material on these better than the material on the 4.0 - So soft!

Great
Very comfortable and loving the double pocket. I think i prefer the 4.0 though due to the waist band. If you have bad love handles like me the waist band twists on these, thats why its 4 stars. Otherwise very good for work and movement and inspired me to get more pairs of different kinds.

What a fit
Amazing it’s just that I hang to the right so my man hood like to peak or the side of the opening but over all awesome.
