Big-and-tall shoppers are often an afterthought in men's underwear, but the OXBALLS SLINGJOCK comes in XX-Large in every colour, and this Black Iron version is a full-feature jockstrap for a 44–46 inch waist. You get the same slider-strap pouch, padded waistband, hip pocket and built-in lifter as the smaller sizes, scaled up, not simplified.
Measure where the waistband will actually sit. For many larger guys that's under the belly rather than at the navel, and the number can differ by a couple of inches. Use that lower figure. XX-Large covers 44 to 46; if you're at 42 or 43, the X-Large (40–42) may hold better. Above 46, this jock will feel tight at the band, and there's no larger size in the range.
Two parts of a jock matter more as the body gets bigger: the waistband and the rear straps. A soft band tends to roll under a belly and creep down. The SLINGJOCK's band is deliberately firm, with a plush inside layer so the stiffness doesn't rub, and it's built to stay flat. At the back, the flat-tube elastic straps have rounded edges. On fuller thighs and a wider seat, thin cord straps can dig in; flat ones spread the pressure.
The slider design helps too. Because the leg straps can move along the pouch, walking or climbing stairs doesn't pull the pouch to one side. On a fixed-strap jock that sideways drag is what makes you adjust all day.
Sitting is the other test. Long drives, desk days and flights all put pressure on the rear straps and the band. Because the seat is open and the straps are wide, there's less fabric bunching under you than with briefs, and the plush lining keeps the waistband from leaving a ridge after a few hours in a chair.
Dark colours are the safe choice if you want the jock to look sleek, and black doesn't show through dark jeans or work trousers. It's also the easiest colour to pair with a harness, a leather vest or a plain T-shirt. If you'd like something brighter, the same XX-Large size is available in Pink Sky, Pool, Red Hot and White Snow.
Inside the pouch is a BUNGEE elastic that OXBALLS uses as a cock-ring lifter, raising and bringing the package forward. A JOKFIT rubber cock ring comes in the box. You can wear either, both or neither. Many people just enjoy the support of the pouch day to day and keep the ring for nights out. If you're curious about rings, read our cock ring sizes guide; since the JOKFIT's dimensions aren't published, it's useful to know your own fit.
Cold water and no heat. Hand wash or use the gentle setting, no bleach, and air-dry on a hanger or flat. Tumble drying, ironing or dry cleaning will shorten the life of the elastic and the 3-D rubber logo.

Helpful answers about OXBALLS SLINGJOCK Upthrust Slider-Strap Jock – Black Iron / XX-Large.
Yes. XX-Large is the largest size and fits a 44–46 inch waist. It's available in all five colours, with the same features as the smaller sizes.
Measure where the band will sit, which for many people is below the belly rather than at the navel. Use a soft tape, keep it level, and don't pull it tight. That figure is what the sizing is based on.
It's designed not to. The band is firmer than a typical underwear waistband, with a soft lining so the stiffness doesn't chafe. Choosing the right size matters: a band that's too tight is more likely to fold.
They're flat-tube elastic with rounded edges rather than thin cords, which spreads the pressure. If the straps leave deep marks after a few hours, the jock is probably a size too small.
OXBALLS doesn't publish the JOKFIT's measurements, only that it's a stretchy rubber ring. Try it and remove it straight away if it feels tight. You don't need to use it to wear the jock.
No. Heat breaks down the elastic and can lift the raised rubber logo. Hang it up or lay it flat to air-dry after a cold, gentle wash.
