I just want to share my recent purchases (last couple of months).
finally I have been able to find golberg jockstraps in UK and literally are exactly the same as a FR jockstrap.
I have made an interesting comparison about sizes. Having in this mix from M to L to XL but definetely not aligned because a Jockmail XL is tighter than a golberg medium.
also I found recently from jockmail the jock briefs and are super comfy, nice feeling when you want your ass covered.
thanks to
