How to put it together
- 1
Put on lightweight, breathable base clothes like a t-shirt and shorts to stay cool inside the suit.
- 2
Insert fresh AA batteries into the costume's fan battery pack and clip it to your inner pocket or waistband.
- 3
Step into the leg openings of the inflatable suit and pull it up over your torso.
- 4
Slip your arms through the designated armholes and ensure the elastic bands fit snugly to trap air.
- 5
Pull the hood over your head, positioning your face clearly in the sheer viewing panel.
- 6
Switch on the fan and allow the suit to fully inflate around you, which takes about one to two minutes.
- 7
Adjust the elastic drawstrings at the neck, wrists, and ankles to prevent air from escaping.
Makeup & hair
No specific makeup or hair styling is required, as your head and hair will be completely covered by the costume's built-in hood and face panel.
Penis for couples, groups, kids & more
- couples
- Pair this with a giant condom costume or a retro 'birds and the bees' outfit for a funny duo.
- group
- Have a group wear various inflatable novelty suits like sperm, anatomical parts, or giant baby costumes.
- kids
- This costume is strictly for adults and is not suitable or available in kids' sizes.
- Plus size
- The inflatable design is naturally oversized and highly accommodating for plus-size body types.
Tips
- Always carry a set of spare AA batteries in your pocket, as the fan must run continuously to keep the costume inflated.
- Navigate doorways and tight spaces sideways, as the costume is significantly taller and wider than your normal frame.
- Drink plenty of water before putting the suit on, as the polyester material can trap body heat quickly.
- Make sure the elastic seals at your wrists and ankles are tight to maintain maximum inflation.
Penis costume FAQ
- How do you breathe inside the inflatable penis costume?
- The costume features a built-in sheer mesh face panel that allows you to breathe easily and see clearly while keeping your face partially obscured.
- How long do the batteries last in the inflation fan?
- A fresh set of standard AA batteries will keep the fan running and the costume fully inflated for about 4 hours.
- Can you sit down while wearing this costume?
- Yes, but it requires care. You can gently sit down as the air-filled suit will compress, but it is easiest to stand or walk around.
Did you know? Inflatable costumes rely on a small, continuous-flow fan that draws in outside air, meaning the suit stays inflated even if it suffers a small puncture or tear.
