The gym classic, soft enough for Sundays.
A jockstrap doesn't have to feel like equipment. The Core Jock keeps the classic cut — support up front, open in back — and softens the whole thing in breathable 100% cotton you'll forget you're we...

Core Jock Black.
I'm a big guy. Bear type of body. C-IN2 Jockstraps are just fantastic. There made with such good quality & fit so well. There are so many brands of Jockstraps out here for purchase including some old school brands. I wear many brands of Jockstraps but by far C-IN2 is at the very top of my list.

A Special Jock Revisited
There's just something special about this jock. I first got the white one, and had to have more. Grey heather and, of course, this black one. While I don't usually like wide waistbands, this one was different. That waistband just felt so good and so different I loved it straight away. Combined with the equally good feeling of the very soft, snug, and supportive pouch, it is certainly a winner. Name the activity, and this jock is right for it. Of course, I love the way it looks as well - and black is always cool.

Comfortable, well-made
A quality product, and comfortable, unlike many of these being sold. Soft cotton, generous sized pouch is comfortable for all day wearing. Does not dig into the legs and you forget it's even there. Holding up to several wearings/washes so far. Size chart for this size is accurate--follow the chart. XXXL fits a 42" waist (though I wear an XXL for most clothing). May not be as suitable for strenuous sports... but for running, lifting, lounging and walking it's great.
