They are great. Good quality


Jonah (United States)
Suuuuuper Comfy

I love this thing, my ass looks great, and its really supportive in the front if you catch my drift. It feels really high quality, I definitely plan on getting another soon!

Wish I could hate this.

I love making fun of things, but I just can’t. This jock is excellent quality and withstands rough treatment. Yes, the sizes run small. With my 34” waist, I’m a Medium in Gap and a Large (or XL) in Pump. I will come back for more. Wish there more colours.

Nice look, Very Fitting!

It’s a very nice jock, but a little tight around the crotch area. Would probably recommend a size up.

Party in the Back

Love PUMP! underwear and Circuit Jock was sporty looking briefs in front but open in the back. Quality and fresh looking is 1 reason I keep coming back to buy on this site. Love it
