Introducing the new SIliSleev Duro Penis Sleeve called the DuroSleev. The DuroSleev is formulated for hanging heavier weight and adding extreme tension with the SiliStretcher. The DuroSleev was engineered for intense stretching sessions, anti-turtling and penis pumping to help reduce fluid retention.

The new DuroSleevs are semi transparent for better monitoring of your penis during your PE sessions. They have less stretch than the original SiliSleevs and are a bit more restrictive yet extremely durable and customizable to fit. 



Measure your stretched flaccid penis circumference at the thickest part of your mid shaft. 

If your stretched flaccid girth circumference is 3" or below, order the .75" (19mm) DuroSleev. 

If your stretched flaccid girth is 3" or over, order the 1" (25mm) DuroSleev.

DuroSleevs inside diameters are available in .75" (19mm) and 1" (25mm) and stretch a little over two times the original size.


The diameters of the DuroSleevs can be custom formed to size by user. One method is to slide the DuroSleev over a thicker diameter pipe and let set overnight. Another method is by using a hair dryer with low heat to slightly soften and form to required diameter.


Stretch your flaccid penis and measure from your pelvic bone to below your glans. Order the closest length that is right above your flaccid stretched length.

The DuroSleev increases penis length by comfortably keeping a constant stretch on penis ligaments and tissue as the microscopic tears from exercise heals, this process is completely pain free. 

As these tears heal along the course of your SiliSleev2 sessions, your body will recognize the gaps created in the penis tissue. As a form of healing, your penis will begin to repair itself in this extended state by going through a process known as "mitosis" followed by "cytokenesis". 

Mitosis occurs when cells within the existing penis tissue begin to divide, known as cellular division, where one cell divides into two. The penis tissue cells will divide over and over again to fill in the gaps (tears) caused by the penile tension process. Enlargement can be noticed in both length and girth (thickness).

In the simplest sense, the nucleus of a cell divides within itself then splits in two, each containing a mirror image of the original nucleus. The splitting of the two cells, once the nucleus has divided, is called cytokinesis, the final stages of cell division and tissue growth. 

The cells will rapidly divide over the course of the treatment and will create new tissue for a longer and larger penis.


What does the SiliSleev2 do?

SiliSleev2s have multiple uses for penis enlargement and tissue healing. 

1) Use a SiliSleev2 to cement penis gains after exercise by keeping the penis in an extended state as your tissue heals. 

2) Use a SiliSleev2 to reduce fluid retention and bruising while using vacuum or hydro penis pumps . Fluid retention causes un-wanted deformities of the penis such as a donut effect and the SiliSleev2 applies even pressure across the entire shaft.

3) Use a SiliSleev2 as a gripping wrap to protect and de-sensitize the penis while using exercise devices such as penis extenders, penis hangers, vacuum belt extenders the lengthMaster , etc.

Can I use SiliSleev2 for manual penis stretching?

Yes, they can be used for manual stretching for better grip and reduce sensitivity to the penis. 


Can I use SiliSleev2 for penis jelqing?

The SiliSleev2 can be used with water-based lube to reduce wear on hands and penis as it slides up and down the shaft during jelqing sessions. With the addition of a SiliRing or DuroRing, blood will remain trapped in the penis for girth expansion.

Do I need additional wraps when using the SiliSleev2 as a wrap?

In most cases the SiliSleev2 can be used as a stand alone wrapping method.

What is the SiliCap2 and when should I use it?

The SiliCap2 is used to protect and compress the head and shaft of your penis while vacuum pumping with vacuum extenders and penis pumps. The SiliCap2 should only be used for exercise sessions, not as an all day cap.

What size is the SiliCap?

The SiliCap2 is 7/8" (2.2mm) diameter x 8.25" (21cm) length (one size fits all) in most case

What size SiliSleev2 do I need?

The most commonly purchased SIliSleev2 is the 7/8" (2.2cm) diameter. This is the sweet spot for most men regardless of their girth. Being that the SIliSleev2 stretches up to four times its' original size, it will accommodate just about every girth.

Sizes include two diameters, 7/8" (2.2cm) & 1-1/8" (2.8cm).
The 7/8" (2.2cm) diameter is for a penis with a flaccid girth of 4” and under.
The 1-1/8" (2.8cm) diameter is for a penis with a flaccid girth of 4” larger.

The SiliSleev2 currently comes in two different diameters and one length.

We recommend cutting the long SIliSleev2 down to 4" when intended to be used with exercise devices such as penis traction stretchers, penis hangers, vacuum belt extenders and can also be used for manual stretching. 

The long SiliSleev2 is intended to be used for cementing penis gains and used for penis pumping but can also be moderately used for everything else when it comes to exercise devices or manual stretching and jelqing.

The smaller diameter SiliSleev2 stretches up to four times its original size, so it can accommodate larger girths as well but will be tighter.

What side does the ridge (thicker end) go on?

When using the SiliSleev2 to cement gains, the ridge of the SiliSleev2 should point towards the tip of your penis below the head. The same goes for penis traction extenders (vacuum as well). The ridge acts as a gripping point to lock the SiliSleev2 to the extender strap or around the vacuum bell.

When using the SiliSleev2 with your penis pump, the ridge goes towards the bottom of your penis, against the pelvic to act as as restriction ring to trap blood in the penis for expansion while pumping.

How long do I wear the SiliSleev2?

As long as you want, it depends on you. Many people wear them all day at work or sleep in them at home once they get accustomed to them.

Does the SiliSleev2 stop circulation to the penis?

No. The SiliSleev2 is very stretchy like a condom and will not cause any discomfort. In the rare case you order a sleeve that is too tight, you can stretch it over a pipe over night to stretch out or use a hair dryer to warm up while stretched.

Can I wear the SiliSleev2 to sleep and to work?

Yes and Yes. The SiliSleev2 was designed so you can wear as an all-day/all-night stretcher. We recommend first getting accustomed to wearing it before you sleep in it.

Can I use lube with the SiliSleev2?

Not while stretching, only use lube when jelqing. Lube will cause the SiliSleev2 to slip off when stretching. Before stretching with the SiliSleev2, make sure your penis is completely clean and dry before your stretch session. You can also use MOSGrip on your penis for extra grip. A little gripping powder will help but not required.

How do you clean the SiliSleev2?

A gentle dish detergent works best such as Ivory or Dawn and warm water. Once washed, air dry, and then powder with MOSGrip or a baby powder to keep fresh.

How do you store the SiliSleev2 when not in use?

Get a zip-lock plastic bag, add some MOSGRip or baby powder and they will stay fresh forever.

How do I put the SiliSleev2 on and take it off?

Roll it up like a condom , stretch over the tip of your penis, and then unroll while you are stretching your penis in an erect state.

Does the SiliSleev2 work for uncircumcised penises?

Yes. It is suitable for both uncut and cut guys. Uncut penis, pull the foreskin back and apply or pull the foreskin forward and tape with micro-porous tape.

What is the SiliSleev2 made of?

A hypoallergenic silicone formula.

Is the SiliSleev2 sticky?


Is the SiliSleev2 durable?

Yes, it is very durable and should last a long time if you properly take care of it. They do not tear easily. However, just like any elastic product, they do tend to stretch 10-15% over time.

How does the SiliSleev2 compare to the Phallosan condom/sleeve?

The SiliSleev2 is much more durable and elastic and will last much longer.

How much does the SiliSleev2 stretch?

They stretch up to five times its original size.

Can I mix and match SiliSleev2 sizes?

Yes. SiliSleev2s can be purchased individually or in sets.

Is the SiliSleev2 packaging discrete?

Yes. They ship in a plain white bubble wrap envelope with the return address saying PPC Corp.

Is the SiliSleev2 covered under the MOS Lifetime warranty?



Make sure your entire penis is shaved clean of hairs

Hairs can create loss of grip with DuroSleev

Make sure your penis is clean, dry and free of oil

If you put lotion on your skin, this will cause loss of grip. Your skin also has a natural oil that can cause loss of grip and you want to maximize grip.

We strongly recommend cleaning and drying your penis then using MOSGrip to remove all the natural oils of your skin and create a tack for maximum grip. Sweat causes slippage as well, MOSgrip also helps eliminate sweat under the DuroSleev.

Make sure your DUROSLEEVS are clean, dried and powdered with MOSGrip

Dirty oily DuroSleevs with pubic hairs in them will cause loss of grip . Make sure your DuroSleevs are clean, dried and powdered before each use.
