Good news! I found very good jockstraps! Let me give some feedback
First one and the best jockstrap ever is the bike, modern, nice and I love the 2 inch waistband. Pouch is roomy but very supportive
As in UK is not that easy to find jockstraps I ordered some from amazon (golberg is not available here). I ordered a karen space and FR one (both Arjen Kroos shop). For the ones that dont know it Karen space is a chinese brand that also has acquired others like seobean, fr, arjen kroos, etc
they sell very affordable (11£ each, approx. $13) and honestly is a 5 star purchase! Very true to size, amazing pouch, waistband, the design! Honestly I fall in love with them and will buy more for sure (they have a FR swimmer jock that I want to buy too!)
I can say that these jocks are the closest that I could find to a bike jockstrap (and saying it is a big statement!).
I have attached some pics for your reference!
