7 Popular Penis Packer Swim Trunks to Take a Plunge in


If your packer’s non-porous, which most are, then it can be submerged in water for prolonged periods of time, as can silicone ones, so if you’re in the water regularly, a pair of penis packer swim trunks can really help for comfort and peace of mind.

Long term packer exposure however to chlorine will degrade it faster. Sea water and fresh water are no problem.

One FTM store ran a three day test on their non-silicone packers and all were reported unscathed after being submerged for this length of time.

Their weight was also measured and all came back no heavier, so promising there – but the challenge with swimming while packing lies more in eliminating any chance of your packer popping out than the wear and tear.

Therefore, a pair of trunks that will hold your penis packer securely is your best bet to stop old Dilbert wriggling free.

The chances of your conventional swimwear holding your packer in place are slim, so it would be wise to invest in some water friendly FTM trunks that you can wear as your swimwear or under it, that won’t stretch disproportionally when doing laps and are primarily comfortable.

So what get the thumbs up?

The following 7 penis packer swim trunks and underwear stand out firstly as reliable swimming attire online, plus comfort and design also get a firm nod.

Note: If you are doing vigorous workouts, then a packing strap (with no leather parts) will come in handy underwater.

Material: Nylon, Spandex, Jersey
Size: 28″ to 50″

The Pete Freestyle trunks are perfect for any aqua recreation. Essentially, they’re really a pair of jocks and a harness in one.

Perfect for a short or long dip, Pete’s freestyle packing trunks are firstly soft and comfortable against your skin.

Made of light weight Nylon, Spandex and Jersey material, the Nylon and Spandex help Pedro breathe, while extracting moisture away from your body, allowing you to keep cooler and dryer.

The Pete Freestyle trunks are V shaped and contoured at the front and can be easily worn alone or beneath your swimwear.

Peter’s secure fit, allows for free movement with zero worry of your packer escaping and bubbling up to the surface.

  • Option for shaft to sit outside via opening through front side
  • Good for wide leg motions, steps, restroom, demanding activities & swimming

2. Budgie Boxer Briefs – Packer Swim trunks + Quick Drying Underwear by Transthetics

Transthetics Budgie Boxer Briefs with inbuilt pouch and elastic loop.


Tailored specifically to be used with Transthetics play packers and STP products such as the Joysyick and the EZP Junior respectively, these budgie smugglers should also fit a number of other packers which have similar measurements to these devices.

So if your packer weighs around 110g, and is roughly 15cm or 6″ in length and has a cup length (if it’s an STP packer) of 3″(8cm) and a width of 2.4″(6cm), then they should be a snug fit.

Suitable for both women and trans guys, they can be worn as briefs and as boxer briefs, plus they have a reinforced crotch seam and an attachment loop for use with the Joystick packer by Transthetics – a harness free realistic FTM play packer which is a carrot shaped Joystick which sits inside the Joystick sheath and can perform ejaculation, urination, vibrations along the shaft as well as at the base, plus there are additional addons.

It’s quite a piece of kit and is better explained by Transhetics here, but with the loop built in to these FTM swimming trunks, they essentially have the potential to harness other packers.


  • Boxer cut holds everything nicely in place
  • Suitable for women and trans guys
  • Reinforced crotch seam
  • Inbuilt loop to attach around packer or Joystick


  • Joystick works slightly better with briefs than boxer briefs
  • Transthetic’s prosthetics in chlorinated water do not fare so well – salt and fresh water are fine

On design alone, these third pair of Jockmail swimming packing trunks have to be included.

Not specifically created for swimming per se, but even those advertised here with a front opening are advised by their manufacturers for you to wear an outer pair or swimming trunks for extra precaution, plus it’s nice not to have your packer too close to your skin when swimming so as to avoid chaffing – so these boxers get the thumbs up for water sports.

Designed for workouts, as they’re both 92% cotton and 8% spandex, they’re made for sweating and all different terrains.

Additionally, being 92% cotton, they’re mercerized which is a textile used for finishing a garment which improves dye uptake, tear strength and reduces potential fabric shrinkage, while imparting a “silk-like luster”.

So they bind well without pinching.

Tip for transforming normal briefs into penis packer swimming trunks

You can transform most budgie briefs into a snug fitting pair of trunks by sewing an elastic loop into the appropriate location (if your packer can be lassoed so to speak).
