  • Honestly I've tried so many methods to enhance what I've got for nearly 10 years, finally found a product that's doing the business for me.
  • I just made my second purchase, I must say it is an ingenius design and concept. Now I have an underwear bulge I can be proud of!
  • Stealth feels awesome, I just adjusted my package and it feels heavy and thick!... cash your check, the Stealth is well worth the money!
  • What I like best is that you can wear it to achieve an enhanced but naturally looking bulge. A great product to increase girth, length and soft size.

Measuring Instructions


To measure length: In the flaccid (soft) condition, clamp your penis head using your thumb and finger. Fully extend your penis to a comfortable stretch. Lightly press the ruler slightly (1/2" only) into the fat pad towards the pubic bone. Measure along your shaft without including your penis head.


To measure girth: Once again, fully extend your penis to a comfortable stretch. Use a measuring tape to measure the circumference of your shaft right behind the penis head. If you do not have a measuring tape, wrap a strip of paper behind your penis head. Mark the strip of paper and then measure the distance on a ruler.


After you’ve measured yourself and double-checked for accuracy, enter your length and girth into the drop-down menus. Our calculator will automatically choose the most suitable size for you. The size code will be shown in the display box for your reference. You may manually adjust it, if needed.

Noticable growth :)

I have been an innerwear and corkscrew user since 2015. I started as a B-28 and and up to a B-32 — this stuff works. No, you’re not going to grow a pornstar package in a few months, but there will be noticeable length and girth improvement with consistent, continued use. I have always been “one of those guys” who has struggled with his grower, not shower, status, Stealth has improved my confidence in that area ten-fold. It’s nice to catch the occasional glimpse every now and then.
I could not recommend Stealth products enough. In addition to what they do for your physically, the company is great. They’ve responded to every concern I’ve ever had quickly and always make everything right.

Caring company

First time I saw the product and how it works I thought it looks like a good idea, and after trying it I can say that this is a great idea, because it works. This is really confortable, you don’t feel you are wearing it. It isn’t like other super complex devices where you feel you have to hide it. You can wear it with confidence. It is well made, the materials are first quality. It is clean and stealthy. It is cheap, they got a good price for it. If you doubt about it, just try it. Measure your penish carefully, to choose the right one. A bit tight is better, because the gland could move inside. The customer service is really good and nice, they want you to be glad with the product. They really care

Best undergarment product

I highly recommend stealth products for men. I have purchased the innerwear and the cyberskin. I love how it enhances my package. It is comfortable and prevents turtling. Best undergarment purchase I have ever made.

Best male enhancement

Stealth for men is the best male enhancement product I have ever purchased. It keeps everything compact but increases the bulge hugely. I wear it every day and really need to get a new one as it is almost worn out. All in all it is a purchase you will never regret.

Hope this will prevent my shaft from turtling. Ordering soon.
