The Jack grip is a penis sleeve that can be used for solo or partner play. This is a open ended sleeve with finger grips on the outside and a ribbed inside for the man's pleasure. More on that later.

The box says "The masturbator that's perfectly fit to your hand and perfectly fit over your cock". Well lets just see....

The Jack Grip is made of Sil-a-gel. There is a small bit-o-smell to it, kinda fruity (can't quit put a name to the smell) but not unpleasant by any means. The material is similar to Jelly or TPR in that it is kinda sticky, which makes every hair and dust bunny stick to it. I do not have a problem with it but you could dust with corn starch before storage to help with that.

This sleeve is textured inside and provides some good stimulation to the penis. Some may find it to big but I find it to be right on. If you want tight just grip harder.

I have a pic of it here https://www.flickr.com/photos/dwtim/4803827034/

The outside is a smooth oval shape that has three finger grips on one side. The finish is almost like real skin, soft and smooth. The inside has ribs and little bead like bumps in between. The entry hole and exit (depending on how you use) measure 1 1/8" and 7/8", over all length is 3 1/2". I can stretch this to fit over my hand with ease.

As far as a "perfect fit". My hand is 7 1/2" from finger tip to wrist and 4" wide. I can only get three fingers on it and there is about 3/4" between my thumb and middle finger. My wife's hand fit the finger grips but could not hold it with one hand due to the circumference, about 10". This makes for some fun holding on to it, especially when "Jack'n" (sorry) fast or when the lube gets on you hand.

O.K. That is the only problem with this toy: the size. After you get over that this is the best feeling sleeve that I have felt yet. By far the closest to the real thing I have tried.
I really like the fit and the open end design. I was even able to put in my penis in soft and stroke from start to incredible climax with no problem. With my eyes closed it feels like a real vagina without the tight entrance.

Is it discreet, lets see grip for your hand, textured hole, soft skin like feel, I do not think I will put in my carry-on. But as it is small you could just put it in a zip-lock and stick in your pocket.

This material is completely anti-bacterial, non-toxic, Phthalate, Latex and Cadmium free. This is the first toy material that I have seen that is anti-bacterial. This is something I hope we see more of, anything to keep things safer.

Because this is a new material to me, I will still recommend safe toy habits: wash with toy cleaner or a mild soap before and after use, dry off before storage, and use a condom if your friend wants to borrow it or you have a new man in you bed.

With Sil-a-Gel you can use water or silicone based lubes. For easy clean up use water based, for shower/tub play use silicone.

The Jack Grip come in a cardboard box with a picture of the sleeve. On the back there is their sales pitch about how perfect the fit is and that this toy is made in the U.S.A., and that it is sold for novelty only.

Inside you will find the sleeve wrapped in a plastic bag. (The bag is about three sizes too big)
You can use the box and plastic bag for storage.

There are no instructions but I don't think that they are required. There are care instructions though.

We find it best to grip this sleeve when it is clean and be sparing with the lube. When there is too much, it will come out the top and go all over, making it hard to hold. We also started to keep a wet wash cloth handy for our hands, this help when you get lube all over.

After we figured out how best to Grip Jack the experience was the best I have had with a sleeve. The wife likes to slid this on me and poke the head out the end then give me oral. With some jack'n she brought me to climax in half the time it takes her without an aid. Big plus for her jaw muscles.

Just for fun I turned it inside out and used it that way, obviously the texture is not there but the finger grips do provide some interesting stimulation.
