Pool is the SLINGJOCK's blue colourway, and despite the name, this OXBALLS SLINGJOCK in Large is a cotton jockstrap, not swimwear. It's cut for a 36–38 inch waist and brings the full OXJOK set-up: a soft-rib pouch that holds you up and forward, leg straps that slide as you move, wide flat elastic at the back and a firm band with a pocket.

Not swimwear, despite the name

The fabric is 94% cotton with 6% spandex. That's great for breathability on land, but cotton soaks up water, sags and takes a long time to dry, and chlorine and salt will fade the colour and degrade the elastic and the rubber logo. Wear it under shorts on a beach day, by all means; just don't swim in it. Think of Pool as a summer colour, not a summer fabric.

How blue wears

Blue is the easy middle ground of the range: brighter than black, less of a statement than red or pink. It pairs naturally with white, navy and grey, and looks good under light-wash denim or with a white tee. If you're building a small rotation, Pool alongside Black Iron covers most outfits. Blue also hides light sweat marks better than white, which is handy on hot days.

Fitting the Large jockstrap

Large is OXBALLS' 36–38 inch waist. Measure at the height where the band will rest, usually a little below the navel. The leg straps are elastic, so muscular thighs or a full seat don't usually push you up a size; the waist decides it. If you're at 39 or like a relaxed band, the X-Large fits 40–42. At 34 or 35, the Medium is closer.

What's built in

The slider straps are the headline. Instead of being sewn to one point, the leg straps travel along the pouch edge, so when you squat, step up or twist, the pouch stays where it should and the straps follow your hips. The firm band won't fold over and has a plush inside layer. On the hip, a small STASH pocket takes a locker key or folded cash. Inside the pouch, an elastic BUNGEE loop works as what OXBALLS calls a cock-ring lifter, for a more lifted front, and a JOKFIT rubber ring is included in the box. The lifter and ring are optional extras; leave them out and it's a supportive everyday jock.

Care

Wash cold, either by hand or on a gentle cycle, without bleach. Hang it to dry or lay it flat. Keep it away from the dryer and the iron: heat loosens the elastic and the 3-D rubber logo. Rinse it after a sweaty day in the sun rather than leaving it in a bag. Sunscreen and after-sun lotions can mark cotton, so let them sink in before you dress, and wash the jock soon if they do transfer. Drying it in shade rather than strong direct sun also helps the blue keep its depth.

Helpful Information

Frequently Asked Questions

Helpful answers about OXBALLS SLINGJOCK Upthrust Slider-Strap Jock – Pool / Large.

Can I swim in the Pool SLINGJOCK?

No. It's 94% cotton, which absorbs water and sags when wet, and chlorine or salt water will fade the colour and wear out the elastic. Wear it under shorts on a beach day, but change into swimwear for the water.

What colour is Pool?

Pool is the blue colourway of the SLINGJOCK. Retailers list it simply as blue. Check the product photos for the exact shade, as screens vary.

Does muscular legs mean I should size up?

Usually not. The leg and rear straps are elastic, and the pouch fit doesn't change with thigh size. The SLINGJOCK is sized by waist, so a 36–38 inch waist fits Large even with big legs.

What's the difference between the lifter and the cock ring?

The BUNGEE lifter is an elastic loop sewn inside the pouch. The JOKFIT is a separate rubber ring in the box. OXBALLS designed the lifter to raise a ring and bring things forward, but you can use either on its own.

Will a blue jockstrap show under light trousers?

Under white or very pale, thin fabric, a mid blue can show slightly. Under denim, khaki or darker colours it won't. The raised OXJOK logo may show its outline through tight trousers.

How do I wash it after a hot day?

Rinse or wash it the same day rather than leaving it damp in a bag. Use cold water on a gentle cycle, no bleach, and hang it up to dry out of direct heat.
